More chapters please

A-freaking-dorable. Daddy Dia. Didn't think I'd say that, but okay! Love it!

This was adorable. I loved the interactions between the two of them. I will be honest, I know nothing of the Harry Potter universe, but still, this story intrigues me! Great work so far!

Please continue this story and update soon!

This is sweet. Hope we see more

This is so precious! When's the next update?! Oh ma gosh! Diarmuid is my 2nd fav lancer!

I love the idea of little Fem!Harry having a mystical knight respond to her plea for aid.
Diarmuid seems like a very good choice (not as intimidating/overwhelming as Alexander, not a battle addict like lancer Cú Chulainn, not as pro-martyr as Arthur, or as intense as Medusa), simply a chivalrous knight who will assist a traumatized little girl as needed.
I am interested in the spiritual/psychic exchange between Master and Servant as well as any training Lancer might give little Rose. Speed and agility training? Magic training?
Horcrux scar Love spot ...?
Whoa! Lancer could use Gáe Dearg to severe horcrux. Then through accidental side-effect or through spiritual merger (to repair damage soul) impart a love spot-type affect! I'd love to see a well prepared and healthy Girl-Who-Lived who wears a mask (similiar to Kakashi Hatake) to prevent the other students from seeing her true beauty and falling helplessly in love.

I love the story! if your health is acting up then take care of yourself and don't make it worse by forcing yourself to write as that will only hurt you more in the long run. just take whatever time you need, better you take care of yourself than end up with a serious medical emergency

Yeah, I can tell you love them so much... and I love you for it! There's not many Fanfiction that has Lancer on them and he's my favorite summon, and I was surprised by how this story turned out! I hope your health are improving. Can't wait to see the next chapter! This is so sweet, I'm dyinggggg! XD

Okay.
I like this.
I like this a LOT.
I haven’t seen a fic where Lancer (autocorrect keeps trying to stop from saying his real name) was summoned by a young fem!harry and decides to treat her as a little sister/daughter despite the master/servant status.
To be honest I found some of the scenes in this very sweet and other made me pissed (at Vernon not your wonderful writing) .
I genuinely enjoyed this and if you decide to continue you can be assured I will watching for the next chapter.
With that said I think I’ve made this review long enough (you probably don’t won’t read all this) so I’ll end here saying:
This was great, your writing was great, the concept intriguing and I’m going to check out other stories of yours later to see if there some other hidden masterpieces.

Harry Potter (Verse)
Power of the Verse
This verse is not particularly strong, with several wall busting spells and athletic human speeds. Even the strongest characters, such as Voldemort and Albus Dumbledore, have only demonstrated city block level destructive capacity, and are below the speed of sound.

However, the verse has a wide variety of hax abilities such as memory erasing, mind control, invisibility, spatial manipulation, instant kill attacks, and teleportation.

The verse also contains creatures called Dementors, that are hard to damage and can suck out souls. It also has creatures called Nundus, which are able to singlehandedly wipe out groups of highly trained wizards.

Voldemort
Age: 71 years old

Gender: Male

Classification: Human, Dark Wizard

Powers and Abilities: Genius Intelligence (He's a master of the Dark Arts and an experienced potioneer), Superhuman Physical Characteristics, Magic, Flight, Forcefield Creation, Limited Animal Manipulation (As a Parseltongue, he can control snakes, even the Basilisk), Curse Manipulation, Death Manipulation (The Killing Curse induces a supernatural death in anything it hits), Fire Manipulation, Memory Manipulation (He can implant false memories into the minds of others), Metal Manipulation (Created a replacement silver hand for Pettigrew and produced a silver shield in his fight with Dumbledore), Mind Manipulation (He can control the minds of others with the Imperius Curse, and can influence, control, and unhinge the minds of others through Legilimency), Pain Manipulation (The Cruciatus Curse can be used to subject victims to torturous pain), Invisibility, Necromancy, Telekinesis, Telepathy (He can invade the minds of others and read their memories and thoughts with Legilimency), Teleportation, Transmutation (He can transform projectiles and elemental attacks into snakes), Resistance to Mind Manipulation (Occlumency allows him to protect his mind from mental attack and invasion), Possession, Immortality (Types 2, 6, and 8; reliant on his Horcruxes), Regeneration (Up to Low-Godly with potions; the Regeneration Potion was able to create him a new body after his soul was ripped from his original one)

Attack Potency: Wall level (He should be at least physically comparable to Harry, who deflected a bludger when he was only 11 years old). Large Building level with regular spells (His power rivals Dumbledore, whose Firestorm is this strong, and he split the Brockdale Bridge in two. He's performed spells that not even Dumbledore would dare to cast, such as Fiendfyre, which is certainly stronger than Firestorm. Capable of creating lightning. Considered to be the most powerful Dark Wizard of all-time, making him superior to Gellert Grindelwald. Created a shockwave that damaged the Atrium in his fight against Dumbledore), Multi-City Block level with more powerful spells (He destroyed Hogwarts' forcefield with a wand that rejected him and after having most of his Horcruxes destroyed, though the effort exhausted him). Several of his spells ignore conventional durability.

Speed: Athletic Human with Subsonic reactions and flight speed (He can keep up with other Wizards in duels, and many of them can maneuver their brooms while in high-speed flight, with brooms as fast as the Firebolt, and track objects as small and swift as the Golden Snitch).

Lifting Strength: Athletic Human, Class 5 to Class 10 with telekinesis (He can move giants and bring down cable towers, and should be at least comparable to Grindelwald, who can hurl cars).

Striking Strength: Wall Class

Durability: Wall level (Comparable to Harry), Large Building level, likely City Block level with magical shielding (Should be far superior to a bounty hunter capable of blocking attacks from Credence's Obscurus and capable of blocking attacks from Dumbledore)

Stamina: Superhuman.

Range: Hundreds of meters with magic, Tens of kilometers with Apparition

Standard Equipment: His wand, and eventually the Elder Wand.

Intelligence: When it comes to magic, Voldemort is a genius, a prodigy and one of most capable wizards in history, with many considering him to have been the greatest and most powerful Dark Wizard of all time. His knowledge on the Dark Arts is so extensive that he has reached and mastered spells that even Dumbledore would hesitate to use, and he makes effective use of his extensive skills in combat, using advanced curses such as all three Unforgivable Curses and Legilimency to read and attack his opponents' minds. Despite his magical genius and charisma, Voldemort is prone to poor tactical decisions due to his obsessions and arrogance, leading him to often perform glaring missteps for no good reason.

Weaknesses: Voldemort is extremely arrogant and sadistic. He has a number of exploitable idiosyncrasies, such as an obsession with magical artifacts, places significant to him, and the number seven. He has no understanding of love, which makes it hard for him to read the minds of others while they are feeling it and often leads to him failing to understand others. He is obsessively afraid of death, and will be reduced to a fraction of his former strength in a spiritual form if his body is destroyed while his Horcruxes remain; if all of them are destroyed, he can be killed for good. When he does acquire the Elder Wand, it does not acknowledge Voldemort as its true master and thus cannot be used effectively. His arrogance often leads to him making idiotic tactical decisions.

Notable Attacks / Techniques:

- Dark Arts: Voldemort is a master of the Dark Arts, considered by many to be the greatest Dark Wizard to have ever lived and possessing extensive knowledge of curses and other sinister spells that even Albus Dumbledore would hesitate to perform. His curses can be so powerful as to bring about the deaths of those who trigger them, causing Dumbledore's health to fail after he put on Marvolo Gaunt's ring and was exposed to the curse and nearly killing him instantly, and even a jinx cast on the position of Defence Against the Dark Arts at Hogwarts was a spell that Dumbledore could not reverse.

Fiendfyre: An extremely powerful bewitched flame that is animated by magic, causing it to track targets. It cannot be extinguished by water, even enchanted waters, and takes on the shape of animals as it rages in an attempt to annihilate its target. Its flames are so intense that it is one of the few things that can destroy a Horcrux. While the spell is difficult to control, a Dark Wizard as experienced and knowledgeable as Voldemort can shape the flames more easily.
Legilimency: The art of invading the minds of others through magic, and then sifting through the mind to gain access to useful information, an art that Voldemort is a master of, using it even in combat to learn his opponents' future actions before they perform them. His power in this is so great that he can even use it to influence, control, and break the minds of others. He is also well-versed in Occlumency, the art of closing one's mind off from mental attack.
Necromancy: Voldemort can animate his victims as the undead beings known as Inferi, which are similar to zombies but not identical. He has, over the years, gathered a sizeable army of these undead.
Taboo: A curse that designates a certain key word as taboo, revealing the locations of any who speak it to Voldemort and his allies. He has cast this spell on his own name, making it extremely risky for any to say it.
Cruciatus Curse: With the incantation Crucio, Voldemort can subject a target to extreme, torturous pain, so intense that they can be driven into insanity by prolonged exposure to its effects. The curse is powerful enough that it can break Memory Charms.
Imperius Curse: This spell, with the incantation Imperio, can be used to control others, putting them into a pleasant, dreamlike state where they will carry out Voldemort's intent.
Killing Curse: The most deadly curse of all, the Killing Curse (also known by its incantation, Avada Kedavra) is a favorite of Voldemort's, who makes liberal use of it in combat. When used, it fires a green bolt of energy that will kill any living thing it hurts, causing them to drop dead without any injury, though Voldemort described it as ripping his soul from his body when it backfired. While lethal, the bolt can be dodged, blocked with inanimate objects, and countered through sacrificial protection, which can nullify its effects.
Albus Dumbledore
Age: 115 (1881 – 30 June, 1997)

Classification: Headmaster of Hogwarts School of Witchcraft and Wizardry, Transfiguration Professor, Only wizard that Voldemort ever feared, Defeater of Gellert Grindelwald, Discoverer of the twelve uses of dragon's blood, Grand Sorcerer, Wielder and master of the Elder Wand

Powers and Abilities: Magic, Legilimency (Mind Reading, Memory Reading, Mental Attacks), Resistance to Mind Reading and Mental Attacks (Via Occlumency), Forcefield Creation, Telekinesis, Teleportation (Via Apparition), Fire Manipulation, Invisibility, Water Manipulation, Transmutation, Animation (Brought the statues at the Ministry to life, who protected him and Harry Potter before Voldemort's Killing Curses), Healing, Status Effect Inducement, Memory Manipulation, Summoning, Flight (With broomstick)

Attack Potency: Wall level physically at his peak. Large Building level with regular spells (Created a firestorm in his fight against Voldemort. Said to be slightly superior to Gellert Grindelwald who created a fire that could potentially burn down Paris. Superior to Voldemort who was capable of creating a huge lightning bolt), Multi-City Block level with more powerful spells (Has been portrayed as somewhat superior to Voldemort and the only one he's ever been afraid of). Possibly higher at his peak (Cast Firestorm while old and incredibly weakened). Several of his spells ignore conventional durability

Speed: Athletic Human with Subsonic reactions via power-scaling

Lifting Strength: Athletic Human physically at his peak. Class 5 to Class 10 with spells (Comparable to Voldemort. Comparable, if not superior to Gellert Grindelwald)

Striking Strength: Wall Class at his peak

Durability: Wall level (Comparable to Harry Potter) physically. At least Large Building level, possibly City Block level or higher with magical shielding (Should be far superior to a bounty hunter capable of blocking attacks from Credence's Obscurus and capable of blocking attacks from Voldemort and Grindelwald)

Stamina: High (Fought against Grindelwald for three long hours)

Range: Several dozen meters, at least countrywide with teleportation

Standard Equipment: Elder Wand (The most powerful wand that has ever existed, able to perform feats of magic that would normally be considered impossible), Deluminator (The Deluminator, also known as the Put-Outer, is a device used by Albus Dumbledore (the first known owner and designer of the one Deluminator known to exist) to remove light sources from the Deluminator's immediate surroundings, as well as bestow them. It looks like a standard silver cigarette lighter), Fawkes (A phoenix and Albus Dumbledore's animal companion and defender)

Intelligence: Genius (One of the most skilled wizards to have ever lived. Capable of devising an elaborate master plan to defeat the seemingly unbeatable Lord Voldemort and was also particularly brilliant at guessing, hypothesizing, and predicting his foes' moves)

Lancer (Fate / Zero)
Classification: Lancer-class Servant, Heroic Spirit, Knight

Powers and Abilities: Superhuman Physical Characteristics, Master Spearman, limited Mind Manipulation (His Love Spot causes women to fall in love with him), Pseudo-Precognition (Can predict his opponent's actions based on his combat experience), Healing and Magic Negation with Gáe Buidhe and Gáe Dearg, Soul Manipulation (All Servants can consume souls to replenish their magical energy), Intangibility and Invisibility in spirit form, Immunity to Modern Weapons (Servants are Divine Mysteries that cannot be harmed by modern weapons such as guns, knives, or bombs unless they are infused with a supernatural aspect such as magical energy or possess a certain amount of age), Resistance to Magic (Including effects such as Petrification, Spatial Manipulation, and Mind Manipulation), Regeneration (Mid-Low; all Servants have regenerative abilities)

Attack Potency: Mountain level (Comparable to Saber. Is stronger than Cú Chulainn in Japan due to receiving more magical energy backup from his masters).

Speed: Massively Hypersonic (Has A rank Agility and kept up with Saber, fighting at speeds Irisviel couldn't comprehend).

Lifting Strength: Unknown

Striking Strength: Mountain Class

Durability: Mountain level

Stamina: High.

Range: Extended melee range, hundreds of meters by throwing his spears (Was confident that he could hit Caster's grimoire from across the shore)

Standard Equipment: His Noble Phantasms, Gáe Buidhe and Gáe Dearg.

Intelligence: True to his class, Lancer is a truly exceptional spearman, easily wielding two spears of varying lengths with blinding speed and grace, taking even the King of Knights by surprise in their first encounter, putting her completely on the defensive with only a single spear while his back was turned to her. He is extremely calm in combat and a brilliant tactician, fooling Saber into thinking that he had abandoned Gáe Buidhe only to kick it up and activate it, successfully landing a clear blow on one of her hands to keep her from swinging her blade properly. In addition, he is manipulative enough to try and charm Saber with his Love Spot and would have manipulated Berserker if he had been convinced that the Holy Grail War was not the honorable battleground he made it out to be.

Weaknesses: Lancer adheres strictly to the rules of chivalry and thus refuses to use dishonorable tactics and may endanger his chances of winning a fight for the greater good.

Notable Attacks/Techniques:

Noble Phantasms
Gáe Buidhe: Yellow Rose of Mortality: A cursed spear, given to Lancer by Manannán mac Lir, the king of fairies. He usually keeps it wrapped in cloth to seal its abilities and hide his identity. Its effects are passive in nature, and its True Name does not need to be released to activate it. Its curse of mortality is always active, and it comes into effect whenever Lancer injures someone with it. The spear lowers an opponent's maximum health limit, and thus prevents the healing of the injured area through any means, as his opponent is already at full health. While it is only really an inconvenience at best for a Servant, against a normal being, any blow would quickly become fatal as bleeding would not cease. The curse can only be dispelled with the destruction of Gáe Buidhe or the death of Lancer.

Gáe Dearg: Crimson Rose of Exorcism: A demonic spear, given to Lancer by his foster father, Aengus Óg. Like Gáe Buidhe, he usually keeps it wrapped in cloth to seal its abilities and hide his identity. As with that of the cursed spear, its effects are passive in nature, and its True Name does not need to be released to activate it. The spear negates magical enchantments and effects. It ignores projections made from magical energy entirely, and chips away things like forcefields and enchantments with every blow. Items that act as a source of magical energy have their connections to their recipients completely severed. It cannot nullify magecraft that has already been completed, such as curses, and its effects last only so long as Gáe Dearg's tip is in contact with the object. In addition, it is not powerful enough to destroy magical objects on the level of Noble Phantasms.

Tale of Tragic Love: Devotion to Grainne: A technique involving both spears that appeared in Fate/Unlimited Codes, Lancer runs his opponent through with a tossed Gáe Daerg to pin them to the ground, before repeatedly attacking his downed target with Gáe Buidhe in a series of spinning attacks. He then finishes them by tossing Gáe Buidhe at his target, engulfing them in bright light.

Class Skills
Magic Resistance: An innate ability that grants protection against magical effects. Unlike the Resistance effect that merely rejects Magical Energy, this ability cancels the spells altogether. Lancer's B-rank Magic Resistance is enough to negate spells with a chant below three verses, and makes it hard for spells on the level of High-Thaumaturgy and Greater Rituals to affect him.

Personal Skills
Eye of the Mind (True): The heightened capacity for observation, refined through combat experience. It works as a danger-avoidance ability, that utilizes all of Lancer's combat experience to predict his opponent’s actions and change the situation in his favor. Lancer's rank in this skill is B, greatly improving his chances of winning due to being able to calmly analyze all possibilities and choose the appropriate course of action, even if his chance of winning is only one percent.

Knight Tactics: A form of fighting method where one grasps the flow of battle and attempts to have their opponent make a mistake in battle even if they themselves are no match of the other's strength. It is a skill not for strengthening one's self but to induce a check failure on the opponents, consisting of the user's composure in their observation power in order to achieve a momentary chance of victory.

Love Spot: A curse that makes women fall in love with Lancer when they see his face. It's unconscious and Lancer has no control over it, though magic resistance can negate its effects.

Kischur Zelretch Schweinorg
Age: Unknown; at least 1800 years old

Gender: Male

Classification: Wizard Marshal, Magician of the Second, Fourth Dead Apostle Ancestor

Powers and Abilities: Superhuman Physical Characteristics, Enhanced Senses (Dead Apostles' senses eclipses that of humans, being capable of detecting alcohol in blood by taste and having a sense of smell that humans can't deceive), Magic, Forcefield Creation, Elemental Manipulation, Energy Projection, Curse Manipulation, Hypnosis. Can travel through parallel worlds, can access magical energy from infinite parallel worlds to utilize an endless pool of magical energy, Clairvoyance, Pocket Reality Manipulation, Time Travel, Reality Warping, Time Manipulation and Spatial Manipulation with the Second Magic (Can observe parallel worlds to see their events and possible outcomes. Can revise records and rewrite the World and events, can create spatial distortions), Immunity to Conventional Weapons (His high levels of Mystery as one of the strongest Dead Apostle Ancestors renders him immune to modern weapons that lack a supernatural component, such as bombs and guns), Resistance to Magic (All magi and Dead Apostle Ancestors have some degree of resistance to magical effects), Immortality (Types 1, 3, and 7), Regeneration (Works by reversing time. Mid normally, Low-High; under the full moon via scaling to Roa), Can exist as a disembodied soul.

Attack Potency: At least Large Planet level, possibly Solar System level (Stopped Crimson Moon's Moon Drop and defeated him in single combat, though it weakened him considerably and he only won because Crimson Moon did not understand Magic). Large Mountain level (Even in his weakened state, he is one of the strongest Dead Apostle Ancestors and should at least be comparable to the others in the upper echelon such as Gransurg Blackmore), at least Island level with Jeweled Sword Zelretch (The true Jeweled Sword Zelretch is much stronger than Rin's flawed replica, which emits a light comparable to Excalibur).

Speed: Unknown, likely at least Massively Hypersonic (Presumably kept up with Crimson Moon during their fight). Massively Hypersonic (At least comparable to Servants, such as Saber).

Lifting Strength: Superhuman

Striking Strength: At least Large Planet Class, possibly Solar System Class Large Mountain Class

Durability: At least Large Planet level, possibly Solar System level Large Mountain level

Stamina: Very high. Can draw upon magical energy from endless parallel worlds, giving him an effectively unlimited pool of energy.

Range: At least Planetary. At least Multi-Universal with the Second Magic. At least Hundreds of Meters. At least Multi-Universal with the Second Magic.

Standard Equipment:

The Jeweled Sword Zelretch: Zelretch's main weapon, a mystic code taking the form of a ritual dagger with a jeweled blade. It has alien knowledge from a far, far future, beyond the reach of modern humanity. Zelretch carries the original, and only those of his lineage can use it in any form. It is the tool he used to push back the mirror image of the moon, through a 'virtually limitless' Ether Cannon. The sword is capable of the Multi-Dimensional Refraction Phenomenon, allowing the user to draw in potentially infinite magical energy. The kaleidoscope-like jewel blade creates a small opening to the same area in another parallel world, though any further interference is impossible, and it draws in all of the magical energy from that space. Magical energy channeled into the blade can be fired off in a blinding stream of light. Also, as a jewel, the sword can also be detonated as a one-shot explosive.
Intelligence: Extraordinary Genius. As the Wizard Marshal famed as the pinnacle of magi and one of the only people able to use True Magic, he is an extraordinarily powerful and gifted Magus, creating Mystic Codes that are so complex that even with all of Archer's knowledge, Shirou couldn't comprehend or analyze it, comparing it to alien technology. He believed that it'd only be possible to replicate his Jeweled Sword generations from now. In addition, his attempts to teach others his magecraft usually ends as a disaster for them, as they usually become crippled or traumatized, further emphasizing the complexity of his magecraft. In combat, Zelretch uses the Second Magic and his own magecraft to devastating effect, defeating the King of Vampires, Crimson Moon in single combat and pushing back a mirror image of the moon.

Weaknesses: Extensive use of the Second Magic at full power leaves him weakened and exhausted. Can't utilize the Second Magic to the same extent as in the past.

Key: Prime Weakened

Notable Attacks / Techniques:

Jewel Sword
The Multi-Dimensional Refraction Phenomenon in effect

The Second Magic: The second true magic to be discovered, also known as "Zelretch" and "Kaleidoscope", in honor of its discoverer. The Second Magic revolves around the "operation of parallel worlds", allowing him to do anything ranging from traveling through them to using them as a source of energy and even revising and rewriting events. Whereas magecraft is the realization of something that technology can accomplish but through supernatural means, Magic is a miracle, something that is impossible through science.

Zelretch can use the Second Magic in a variety of ways but the most well-known is through the Jeweled Sword Zelretch, a Mystic Code taking the form of a ritual dagger. Using this, he can access the magical energy within the endless sea of parallel worlds, giving him an effectively limitless pool of magical energy to use for his spellcasting.

Dead Apostle: Zelretch is a Dead Apostle, a superhuman, immortal, vampiric undead being that has refined his inherent human traits throughout his unnatural lifespan, allowing him to reach supernatural levels of strength. As one of the strongest Dead Apostle Ancestors, his mystery would be high enough to render conventional weaponry useless. As an Dead Apostle Ancestor it's also possible for him to exist as an phantom even after losing his physical body. In addition as one of the Dead Apostle Ancestors within the first ten ranks, Zelretch is impossible to destroy with normal concepts.

Curse of Restoration: A Dead Apostle's method of regeneration, which works by reversing time whenever they receive an injury. Its effectiveness is tied to the phases of the Moon.
Magecraft: Zelretch is an incredibly masterful magus, made evident by his high ranking title of Wizard Marshal within the Mage's Association. His mastery over magecraft is such that he is considered the pinnacle of magi. By utlizing the Second Magic in combination with a special magic circle called "magic square", he was able to unleash a 'virtually limitless' Ether Cannon.

This is so cute omg, that part wherelike he might have his own daughterkilled me d'aaawwwww

This is quite cure for a start..
should be interesting to see how it develops
