Finally, third chapter is up! I hope I can keep this up with my busy life. Haha.

xirons20, Rodvek97, Hoppy854 – I'm glad you found this story interesting. Thanks!

NoNameToSeeHere – Thanks for the tip! I'll definitely look into it.

DISCLAIMER: I don't own Naruto, Fate-verse and any other anime/manga/manhwa references that might be used on this story, aside from the concept of this fanfiction.

IMPORTANT NOTICE: I'll have some minor changes on some in-universe laws/rules of Nasuverse to fit this story's own lore. Please take note.

"Chaldea will handle all the bills for this kid's hospitalization." Olga Marie said to Kushina and Minato while Jiraiya leaned on the wall near the window of the hospital room.

"Thank you very much." Minato smiled to the Director of Chaldea.

"But still, to have such a monster appearing without warning in a public school… what do you think might have happened, Director?" Jiraiya asked in a professional, serious tone.

"If you're an ordinary person, I might not give you any information. But… Jiraiya-san, as an A-Rank Hunter who helped us resolve that dungeon break and with you being a relative of the family of the injured kid, I think I need to answer you properly." Olga Marie muttered. With a nod, she instructed her bodyguards to close the door of the hospital room.

'A-Rank Hunter… huh…' Naruto mentally noted, especially the term Hunter.

"…" Kushina sat on the side of Naruto's bed while Minato and Jiraiya didn't move.

"As all of you already knew, a Dungeon is a world that can only be accessed thru a space-time portal called Gate. This Gate randomly appears on a random location globally. A Dungeon is technically a separate world and not part of this world. Nothing can be found within a Dungeon, except for Mana Crystals… and Monsters." Olga began her explanation.

"A Dungeon's Gate must be closed in the span of 7 days. And it can only be closed by defeating the Boss Monster of the Dungeon. And that Boss Monster is guarded by other monsters, ranging from tens, hundreds , or even thousands in number." Jiraiya said, his gaze directed towards Minato, Kushina and Naruto. "Failure on defeating the Boss Monster and closure of the Dungeon after the 7th day will result in a Dungeon Break, releasing monsters inhabiting the Dungeon."

"And that will cause major destruction and casualties." Kushina summarized while narrowing her eyes. She then gripped Naruto's right hand lightly with both her hands.

"So… how do you deal with these… Boss Monsters of each Dungeon, Nee-chan?" Naruto inquired, directly looking towards Olga Marie.

"Since the appearance of the first Dungeon 10 years ago, random individuals appeared with powers and capabilities to deal with them as well. As if chosen by fate, these individuals were tasked to enter the Dungeon and subjugate the Monsters. We call them… Hunters. And Jiraiya-san is not just one of them. He is one of the highest ranking among A-Rank Hunters of this country." Olga then looked towards Jiraiya. Jiraiya then replied with a nod.

"Wow, you're pretty awesome, Jiraiya old man." Naruto reacted, trying to match the enthusiasm of his current 12-yr old appearance. "But if it requires 7 days before a dungeon break happens, then you should have enough time to deal with it even before the dungeon break from our school happen, am I right?"

"That is a rare accident actually." Jiraiya replied. "The Boss Monster on a Dungeon a few kilometers away your school casted a warping spell to one of its more powerful minions during our raid against him, allowing that monster to be warped outside the Dungeon, specifically, on your school. And the rest is history. It is a once in a blue moon incident."

"So that's the gist of it." Naruto muttered to himself silently. "Nee-chan, how do you determine if someone is capable of becoming a… Hunter?" Naruto inquired again while acting continuously acting in child-like demeanor. However, this is a very important question for him. Does being able to see holographic, RPG-like interface automatically equate as being a Hunter?

"We have a special device within the Chaldea Security Organization created from Mana Crystals used for determining aspiring Hunters once they become 15 yrs of age." Olga Marie replied. "That device also automatically unlocks the power of the potential Hunter, determining their Rank."

"Rank… do you mean… Level? Something like… RPGs?" Naruto further clarified.

"No. Ranks are fixed, and once a Hunter was determined together with their Rank, that's it. After all, the Rank determines the full power of the Hunter." Olga then looked towards Jiraiya. "Ranging from E-Rank being the weakest to A-Rank being the strongest, once you were classified on one specific Rank, there's no other way possible to increase your Rank."

"No matter how hard an E-Rank train, there is no way possible for him to defeat a lazy D-Rank in a direct combat. That's quite unfair, if I may say." Jiraiya summarized. "And there also exist an entirely different realm of power… the chosen ones, the S-Rank Hunters…"

'…' Naruto narrowed his eyes after hearing such information. Yes, the Ranking System is quite unfair. But more importantly, he seemed to not fall on such categories with him being a [Player]. 'That's enough information for now…'

After few more inquiries from Minato and Kushina, Olga Marie Animusphere left the hospital with Jiraiya escorting her. Since he's already recovered and his hospital bills have already been taken care of, Naruto was finally discharged after a few hours.

Upon arriving at their residence, Naruto was greeted by a simple yet fully furnished home. He smiled after he saw a picture of his younger self together with his mom and dad. He can't help but think if this would be what could've been if Minato and Kushina didn't die from the Kyuubi's assault back then. With Kushina cooking for dinner and Minato doing other chores, Naruto went up to his room.

'Change of plans. I'll take care of the messages from my Inbox later once Mom and Dad was asleep. For now, I need to try something first.'

He locked the door, immediately implanted a sound-proofing and strengthening seal on four corners of his room, then immediately opened his [Status] Window, then to his [Skills] Window.

[Player Specific Skills:]

[Servant Summon x1 (Unlocked)] (Requirement: Authenticated [Player]) (Cost: 3 Saint Quartz)

'I have met all the requirements…'

Naruto then drew the 3 Saint Quartz from his [Inventory] window.

'Good thing I have fair share of RPG experience while playing together with Boruto.'

He then tapped the [Servant Summon x1] link.

[Servant Summon x1]

[Allows the [Player] to materialize a Spiritual Consciousness as a Servant to aide the [Player]'s progress.]

[The summoned Servant will depend on the [Player]'s affinity.]

[Once summoned, the contract between the [Player] and the Servant can only be broken once the [Player] dies.]

[1st Summon is a guaranteed Servant. Succeeding Summons will only have 20% success rate.]

[Continue the Summon?] [Y/N]

Naruto visibly gulped after reading the skill description. The description is precise, yet so vague. Based on his affinity, what kind of Servant will he Summon? Is it a talking toad? Well, he is a Toad Sage from his home world. Giant Beasts? Well, he is the Jinchuuriki of all Tailed Beasts. Sasuke? He can't even think of him being a Servant who will act for him.

But one thing is for sure. Summoning a Servant will definitely give him appropriate intel on what he needs to do. If the Servant happens to have sentience then even more so. Clenching the Saint Quartz on his right palm, he then sighed exaggeratedly.

"Here goes something…"

[Yes. [Y]]

In that instance, the three Saint Quartz seemed to vanish and the light of his room disappears. Then, a complex magical circle appeared on the floor in front of him. Lightning and fog created from pure mana enveloped the entire room. After a few seconds, a silhouette of a person can be seen standing on the middle of the disappearing magical circle…

The fog and lightning then disappeared together with the magical circle. Lights also returned after few flickers from it. All that's left was him, and the Servant kneeling its left knee on the ground.

The Servant then slowly stood up, revealing a teenage girl with well-endowed body. She was wearing dark purplish armor that somehow resembles that of medieval knights. Her pink-colored hair somewhat covered her right eye. And the most defining feature of her was the gigantic, cross-shaped shield with circular dome on the middle equipped on her right arm.

"Servant Shielder, Mashu Kyrielight, has responded to your Summons." The very first words that came out of the female knight was filled with valor of a warrior and sincerity of a charming young girl. "May I ask, are you my Master?"

And done! Thanks for reading! Please drop some reviews for motivations. Most writers need it badly. Thanks again and till next time!
