In a forest just outside of Ryuudou Temple, a summoning circle can be seen. Unlike most summoning circle used in the holy grail war. This one has a star drawn into the middle while a sword resembling the ultra sword can be seen resting in a altar behind the circle.
Heed my words, My will creates your body...
The circle glows blue as voices can be heard from everywhere...
And your sword creates my destiny. If you heed the Grail's call,
The circle glows even brighter than before and the source of voice is not been seen.
And obey my will and reason, Then answer my summoning!
The star drawing began to spin somehow...
I hereby swear, That I shall be all the good in the world,
The glow suddenly turn pink while the star turn yellow.
That I shall defeat... All evil in the world!
The glow exploded showing a very small figure.
Kirby The Pink Hero that detroys evil is here...
The baby star warrior look around with confusion of his surrounding. He was in his house, and now in a middle of a forest.
He doesn't recognize the trees nor the forest for that matter, Kirby look down and see the same circle as when it appear below him at his house. And noticing a sword awfully identical to the ultra sword he use as a final attack in his sword form.
Kirby walk around for a bit until he began to know the details of the holy grail war in a instant.
A war where seven human and seven spirits of hero compete together as master and servant to kill the other master and servants to get a wish from the holy grail.
Kirby realized that his supposed master is nowhere to be seen.
The puffball look down in sadness at the prospect of being abandoned.
He pick up the sword on the ground out of curiosity.
The sword is a perfect copy to his ultimate sword albeit a smaller version of that sword but perfect nonetheless. It suddenly disappeared in blue smoke.
Kirby look at the spectacle in amazement until he receive another information in his mind.
Heroic spirits are very strong beings that no human could never match, they are powerful and almost unstoppable to any human however they need mana in order to exist, the master are there to provide their "servant" with their own prana to sustain them.
They are classified by their class, parameter, skills, and noble phantasms. They are seven class in the holy grail war, Saber, Archer, Lancer, Rider, Berserker, Assassin and Caster.
Kirby tried to figure out what class he is until another information happen.
Kirby learn that he is a Saver. A class meant for those who had save a race or save their planets from doom.
The newly named Saver look at himself in confusion… Why is he a Saver class servant? A class not meant for this war and yet here he is…
Kirby look at the night sky with determination at finding the truth and stopping evil to get a wish from this war.
"Poyo!" Kirby said as he create the warp star.
He notice that calling the warp star is significantly easier to summon as heroic spirit(even though he doesn't understand what it means) he could even call the star ship somehow.
The pink servant jump on his transport and fly away to see Fuyuki city.
Under the night, the master of rider Waver Velvet looks at Rider who had use his noble phantasms with slight fear.
"This is the ox chariot that king Gallia has once offered up to Zeus. It's renown reputation must be the source of my designation as a Rider class Servant. If you want the Grail, than find me another Hero or two someone worthy for me to fight! Until then, I shall entertain myself by sitting here and looking at these maps. That will not pose a problem will it?"
"Oh uh..." Waver said in fear.
Rider look at his master before noticing something.
"Will you look at that! A shooting star! The gods have smile on us!" Rider said which confuse Waver until he looked.
"A shooting star… In a middle of where artificial light make it hard and yet it can seen rather close actually." Waver said silently before realizing something.
"Wait a minute! That can't be star! It's impossible to see from here!" Waver pointed out.
"Huh?! Well it have to be a servant then! I will not miss this opportunity!" Rider said as he pick up his master as he get on his chariot.
"Wait no I'm afraid of heiiiiiights!" Waver scream as he and Rider fly to follow the star.
Kirby look at Fuyuki city with curiosity on his face… until look of serious appear on his face upon sensing a servant coming to his way.
Sounds of hooves hitting the ground get stronger until Rider see Kirby on the warp star.
"Oh? Is that a servant? It look so adorable!" Rider said to which Waver looks at Kirby.
"I… I don't know what it is, But he using a star as transportation. It must be a star attributed servant." Waver said to which surprise Rider.
"Star attributed? Then it must be very powerful then." Rider mention while smiling.
"I need a closer look at it. Rider can you do something about it?" Waver asked.
"I think this might work." Rider said before saying.
"Hey I'm not here fight! I want to talk!" Rider said which annoyed Waver.
"You can't just declare you're not here to fight!" Waver argued before the warp star stop.
"Did it just stop?" Waver couldn't believe what he's seeing which cause Rider to laugh.
"See. Now I want a closer look." Rider said as he get a better look
"What the-!? He's so small!" Rider said in shock alongside Waver.
"How could a servant be this small to begin with?!" Waver said while looking at Kirby.
"Hello there fellow servant! May I ask what class are you?" Rider asked testing his luck.
"Savar." Kirby tried to say.
"Saber?" Rider asked in confusion.
"Saver." Kirby said once more.
"Saver? Impossible, that shouldn't be in this war.?" Waver asked.
"Saver! Saver! Saver! Saver!" Kirby repeated over and over.
"It's like talking to a baby." Waver whispered to Rider.
"Well then Saver. I here to ask to join me in this war!" Rider said proudly as Kirby look at him confused however Waver look at Kirby with a newfound fear.
"W-what the hell is this? It's parameter is insane! Rider! Get us out of here!" Waver said to Rider.
"What do you mean?" Rider said confuse by his master's outburst.
"GO!GO!" Waver scream before using his command seal.
"What is going with you!?" Rider said before going off leaving a very confused Kirby behind.
After they're gone, Kirby simply continued his flight to a tall building to sleep in.
"Master! What happened!?" Rider asks Waver about his outburst in the house.
"Wherever it is… Saver's parameters is outright insane… How can something so small be this powerful?." Waver said which made Rider curious…
"What is Saver's parameters?" Rider said as Waver pull a piece of paper and write it for a bit and show it to Rider.
Rider open his jaw wide open at the sight at the parameter of Kirby.
"Huh!? Saver is that powerful!? Well I can definitely tell this, he could very well be able fight all the servants in this war and win." Rider said before laughing.
"Why are you laughing!? We can't win against Saver!" Waver said as he panic.
"Don't you get it!? I long for a challenge and I would love to fight him at my peak! I could even rally the other servants to fight Saver if he ever goes for the kill. Which I highly doubt." Rider explain, confusing Waver on the last parts.
"Why do you doubt about him not going for a kill?" Waver asked.
"I seen that look on his face… It's a face of innocent child or even a baby." Rider said as he look at Waver.
"Of course unless his master use a command seal, I doubt Saver would kill a servant or even a master, of course that my speculation." Rider mention to which Waver replied:
"A heroic spirits that might be a child or a baby? I will not believe that Rider! And I used a command seal! This is getting worse! There no way this is getting any worse than this!" Waver said before sigh and start using his familiar to see the Tohsaka manor at just in time for Assassin's "death".
Kirby woke up from his needed nap on top of a building… he sees the sun of this world making it morning.
Saver stand up and went to the edge to see humans walking around.
"Poyo…" Kirby mutters at the sight.
While Kirby has seen humans before since one of his friends is a human, he never seen so many humans in one place! He decided to look around Fuyuki city to see potential place to eat.
Normally he would just called the warp star but he was informed by the grail to keep the holy grail war a secret to everybody except the masters of this war.
Kirby saw a blue balloon coming up from the bottom, he had a idea.
He inhale and his body inflated like a balloon. Kirby then started to float and started air jumping to get him higher.
After a couple of sight seeing, Saver sense a servant among the humans. He goes down without being seen and use a copied essence in his stomach to turn into his ninja ability to gain the presence concealment skill.
With this skill, Kirby follow the servant and her master.
The servant which look like a blond female human sense Kirby's presence earlier pull her master a albino human, to another way.
"What's wrong Saber?" The homunculus said.
Saber whispered to Irisviel about something close by, the fake master nodded in seriousness.
Kirby followed them to a beach where the master seem to have some fun stepping to the water.
The servant look around, careful of not letting her guard down to Kirby.
As night grows near… Both servant has sense another servant making itself largely know in the docks.
Kirby decide to go there instead following Saber.
After a couple of hours, Kirby reached to the area albeit late considering that Saber is also there somehow, fighting against another servant who use spear making him Lancer...
Saver watched as both combatants fought, Saber had the upper hand until Lancer hit her with his spear somehow bypassing her armor.
After that Saber's master heal her with magic while Lancer prepare himself for another attack from Saber who just dispel her armor for more speed.
Saber rush him with all her might to kill him, however Lancer got a surprise hidden underground.
As soon as Saber got close, Lancer use his leg to pull a yellow spear which surprises Saber.
As soon Saber got close, she was able dodge a fatal blow to her head while also cutting Lancer's hand a bit at the cost of him cutting Saber's arm a bit.
While Saber was able to do damage to Lancer, her arm is bleeding a lot more compared to Lancer' cut which is just droplets of blood.
After some talks involving their real identity and the reveal of Saber's wound unable to heal thanks to Lancer's Noble Phantasms, they suddenly hear clapping.
"What..?" Both Saber and Lancer said.
Both servants sees a small pink creature clapping despite its nubbly arms.
"Well... That just adorable." Lancer admitted.
Saber blushed while Irisviel squeal at Kirby due to it cuteness.
Kirby inflates and float towards the servants.
As he lands on the ground the puffball look at them with a determined face.
"Poyo! Poyo!" Kirby said as he wave his hands.
"Odd... That the same presence I felt at the stores..." Saber mutters as she soon piece it together.
"It's a Servant!" Saber said as she pointed at Kirby.
"You're right!" Lancer said in realization as he sense it more clearly.
"It's… Broken, like it wasn't meant to be here at all…" Saber explains as Kirby look at them with his cute eyes.
"You! What servant are you?" Lancer asks while Kirby look at him.
"Saver!"
"Saver? There is a class like that among the heroic spirits. But a Saver class servant in a holy grail war?" Lancer said in confusion as well Saber who look at him confused.
"Poyo! Poyo!" Kirby continue to say as both servant look at him confused.
"Is it challenging us?" Saber said while Lancer look surprised.
Kirby nodded at them while crossing his arms.
"Well then maybe I should fight him considering of your condition~..." Lancer said while smiling which cause Saber to look at him with spite.
Kirby shake his head which shock both servants.
"Saver wants to fight us both?!" Saber said while Lancer look at Kirby with shock.
Kirby nodded.
Away from the battle, two figure can be seen viewing the odd sight.
"How is Saver doing that? He just a head with arms and feets." Waver said while Rider smile at the sight.
"HAHA! Now we will know how Saver fight! Good thing he showed up! I would have intervene the fight." Rider said which cause Waver to act up again.
As the servant and master argued over the intervention from afar, Saber and Lancer prepared themselves from Saver.
"If Saver is confident of his abilities. Then we should be careful…" Saber said as she hold her sword in one hand due to her injuries.
"I wonder what surprises Saver has." Lancer mention before pulling both of his spear up.
Kirby open his mouth and inhale where Saber and Lancer is at.
"What is this?!" Saber and Lancer says at the same time surprises at Kirby's trick.
The cracked concrete from their fight began to move as all the available loose concrete went towards Kirby.
Kirby close his mouth when all the concrete went there and swallowed it. His skin turned brown as a helmet show up out of nowhere and place itself to Kirby's head.
Both servants look dumbfounded at Kirby's transformation and that include everybody seeing this sight.
From the wide eyes of assassin, Kirei just look surprises at the transformation.
"What happened?" Tokiomi asks his apprentice.
"The eighth servant transformed, just by swallowing some concrete…" Kirei answers Tokiomi's question.
Tokiomi nearly choke his drink, he was not please to learn a eighth servant is somehow in this war. And even more displeased to learn that it has a noble phantasm that allows it to transform.
"Anything else?" Tokiomi ask after calming himself.
"Servant is actually gaining the upper hand." Kirei Kotomine said as he view the battle.
Earlier to that conversation, Kirby jump and turn into stone fall where both servant are standing.
"Shit!" Lancer said as he jump away including Saber.
When Kirby lands it create a shockwave which cause even more damage to the ground.
Kirby turn back and rush toward the servants, when the puffball got close he stone uppercuts Lancer in the stomach knocking the air out of him.
"He-He's strong..!" Lancer said in shock at Kirby's strength.
Saber decide to attack Kirby from the side. Before she was about to do a slash on Kirby, he turn into stone again and the slash didn't do anything to him.
"What!? It didn't even scratch!" Saber said and perform multiple attacks against Kirby while Lancer did the same after recovering from the puffball strike.
"Even Gáe Dearg had no effect on Saver's stone! Is it not magic!?" Lancer mention in disbelief.
Lancer's words bear true because stone isn't damage in anyway possible.
Kirby quickly turn back and jump while at the same time inflate and fly away from both servant.
Saber and Lancer look at Kirby who focus his body for a bit and summon a helper while taking his stone ability away.
"Wait what!?" Both servant said as the newly formed Rocky helper use his ability to turn into stone.
"It can do that!?" Says Kayneth El-Melloi Archibald who just stare at Saver's abilities from a top of the warehouse in shock.
Kirby then inhale at both servants which hold their footing but Rocky attempt to crush them.
"You got to me kidding me!" Saber said in frustrations as she dodge the attack but the inhale nearly made her lose balance.
"At this rate, we get suck in!" Lancer said as he tried to attack Rocky but he is still in rock form.
Kirby continue his assault until he jump to avoid a lightning strike courtesy of Rider who came down with his chariot alongside his master, telling everyone his name while also asking the servants to join him.
Kirby looks at everyone confused at the events while both servants denied Rider's offering and Lancer's master began to threatens Waver for stealing his relic.
Rider calls out on somebody which resulted a golden servant materialising on top on a lamp post.
The servant called Archer suddenly insulted everyone with pride and arrogance before a dark explosion happen.
This explosion come from a servant called Berserker who appear in the smoke while looking at Archer.
The gold servant was easily insulted and use Gate of Babylon launching weapons at Berserker who simply grab the weapon and destroy the other one.
Kirby wanting to get another ability, went to where Berserker is and look at Archer.
"What is this? Saver wants to fight me? Hmp. Learn your place mongrel." Archer said as he focus his gate at Kirby.
Archer launches swords at Kirby who simply inhale at them much to everyone surprise.
"What!? You can inhale weapons without harm!? Wait… I can't call those weapons back! You thief!" Archer said in anger as he throw even more weapons with greater velocity but Kirby turn into his sword ability and deflects the weapons away.
Everyone simply look at Kirby with shock once again… At the display of Kirby's abilities and sudden master of sword clearly shows that he is not to be underestimated.
"Why you..!" Gilgamesh look at Kirby with anger until he suddenly calm down.
The golden servant look around while cursing his master's name before going away.
Kirby look confused before hearing combat, the puffball look and see Berserker attacking Saber ruthlessly and Lancer attempted to help but his master use a command seal and force him to fight Saber.
Kirby look at them with disappointment before deciding to help Saber. The puffball may not know much about being honorable knight like Meta Knight. But he know the difference thanks to his battle with the said knight.
Saver rush toward the servants attacking Saber and use sword beam at them which cause them to jump.
Berserker tried to get to Saber but the Rocky helper show up blocking the mad servant. The servant then fought Rocky but the helper create a stone fist and uppercuts Berserker in the stomach.
Kirby quickly fought Lancer with great ferocity. While the spear wielding servant can fight very well but when you're fighting against a creature very small with incredible strength and speed while also carrying a sword albeit a very small one.
Your going to have some serious problem.
Lancer was able to keep up with Kirby's relentless attack but he can't get close to Saber.
Berserker continuously fought Rocky with great difficulty, the small size of the creature give an unfair advantage to the helper while also turning into stone to tank the damage.
After some struggle, the mad servant was able to do a fatal blow on Rocky causing the helper to slowly explode blinding everyone with the explosion.
Before Berserker would rush to where Saber is despite being blinded, Kirby quickly kick him to one of the crate with no problem.
Lancer tried to attack Saber due to the effect of the command seal but Kirby throw his sword at the duel wielding lancer at the cost of his sword ability forcing Lancer to dodge.
"Did Saver lost his sword form?" Saber mutter for a bit in confusion.
Kirby look at Lancer with determination until Berserker hit the puff ball with the lamp post launching the pink saver to a wall, but much to everyone shock Kirby wasn't hurt nor injured he doesn't even seem to noticed like he felt it at all.
"How tough is Saver again?!" Rider said dumbfounded by the sight.
"His endurance is something I never thought any servant could have!" Waver said in shock.
Kirby look at both servant ready fight again. Berserker tried to attack Kirby with his fist but the puff ball did the same, despite the mad enchantment the mad servant has… Berserker still lost exchangement shocking everyone else about Kirby's strength being higher despite his appearance.
"What!? Saver surpassed the strength of a berserker!? Just how powerful is that thing?!" Kayneth said in shock and disbelief.
Lancer tried to attack Kirby but the puff ball put his guard up and block the spear strikes with no problem.
"Are yo-! Ugh! How are you blocking all my strike!? Is not as hard like your rock form but it is enough to block my noble phantasms!" Lancer said in frustrations. While he was glad that Kirby want to protect Saber and to save his honor, it is still frustrating that Lancer can't do anything to Kirby.
Before they continue, Rider came along and use his chariot to run over the mad servant and telling Lancer and Berserker to leave or else he fought alongside Kirby.
Berserker leaves and Lancer smile at his master orders to retreat while thanking Iskandar and Kirby before leaving.
"I must admit Saver, you're pretty good despite being so small!" Rider said as sit down and look at Kirby.
"I mean. Look at you! You probably the most smallest creature I ever seen!" Rider said as he laugh.
"I thank you Rider and Saver for your assistance… I must ask however, Why would you two help me?" Saber asks Rider and Kirby.
Rider explain to Saber about her unfinished fight against Lancer and hoping that their rematch would happen.
"What about you?" Saber asks Kirby.
"Poyo! Poyo poyo!" Kirby said which cause both servant and their master to sweat drop.
"Aww! He so adorable!" Irisviel said as she look at Kirby.
"I don't think Saver can talk much." Waver said while trying to resist Kirby's adorableness.
"Your right about that. Do you have anything to say?" Rider said to which Kirby responded with.
"Kirby!" Kirby said his name unaware the rules of this war.
"Kirby? Wait… Is that your name!?" Rider said surprises at the reveal.
The puffball nodded much to everyone shock at his carelessness.
Kirby began to crave some food so he wave at the servant and fly away with his warp star alongside looking for food.
Saber and Irisviel look at Kirby with shock at the display this also include everyone watching the flight.
"How are we supposed to beat that!?" Kiritsugu said in disbelief.
Author's Note: Alright this wrap up with the one shot. I think. Yeah depending on the views I might continue this story so maybe this wouldn't be one shot. And if you guys are asking on how Kirby can be so damn strong? Make some research. Trust me Kirby can ruin everyone day very quickly. Look at the research part of Kirby vs Majin buu deathbattle, while they missed a lot of things and it is kinda outdated so you have look other website or something, it can give you guys a good view on Kirby's power. This is also based around a spacebattle forum with a similar story like this.
