Truck-kun.... But 13 year too late

(A/N: Hello. So I've decided to continue writing first based on what I've seen in the comments. I said the vote would be 24 hours but I just couldn't stop myself from writing. I can't remember the story I last though of but I've just had another inspiration. So here I am.

The name Sentsuki Kaito has been chosen using an online randomizer. The last name will be in front of the first name when I write. Cuz I sound better to me, like Uchiha Madara, Uzumaki Naruto, Hyuga Neji....

I won't relate anything to his past in Terra but he'll be using the knowledge acquired there, e.g. Magic. The story will just be the reason for his action or personality.

he may seem OP but he won't. Not yet that is. I don't want him going in and stopping all the fight/war and saving everyone.

That's about it.)

( An Unknown Place)

* Levi's POV *

After what I assumed to be a truck fell onto me. I came to this place it's exactly like my subspace but all my thing are missing. My Grimoire, weapons, relics and even the Destroyer (the big giant).

Did I create a new space? Or is this heaven? I'm starting to think that that is truck-kun and he's sending me to another dimension. If so you're 13year too late. LATE I SAY!!! 13 YEARS!!!!!!!!!!

I can't open a portal, so I'm assuming I'm in another dimension. Using Psyqualia(his magical eyes, if you remember) to looked around, I feel my mana draining fast. It's like I've lost my mana or at least it's capacity decreased. Feeling that I closed turn Psyqualia off. Feeling tired I i blacked out again.

Waking up, my body feels unfamiliar again, like when I first arrived in Terra. I'm now on a bed, in a room I've never seen before. The room is quite simple : a bed, a desk with a lamp, lights and a shelf full of scrolls. Wait, SCROLLS? Did I travelled back to Earth? Am I somewhere in the east?

Getting up with this unfamiliar sensation, I walked to a mirror. Looking into it I see a younger me, a 5 years old me to be exact. (Still look like Killua) I was a little surprised, a little cuz not the first time.

What I couldn't belive is that my mana is gone, not even an empty tank. I've read that Mana System needs to be activated to feel and start absorbing mana naturally. Does that mean I need to activate it? But I didn't have to the first time. Well no harm in trying. I sat down and start absorbing mana. The mana in the air is thin but it'll do.

(1 hour later)

I finally activated my Mana system. My mana pool decreased a lot, or maybe this body never had one. Finally, I activate Psyqualia's Energy Vision to scan my surroundings,trying to find anyone.

What I saw shocked me, I can see that there is a different type of energy flowing in my body. I didn't mind it, but I'll have to look at it some other time.

I opened the door and went out, I can see a corridor with circular markings on the wall. There are lit candles illuminating the corridor, making it quite dark.

I decided to go along it and maybe I'll find a way out. If only I had enough mana to use gate of Vahalla, I wouldn't have to go through this scary corridor.

Withbno choice I walked along I. I kept walking until I heard a sound. "hiss" coming from behind. Turning around, I saw hundreds of snaked slithering toward me. "Oh Hell Naw!" I screamed before running away. I kept running until I knocked into something or someone?

"Kaito-kun. Did the snakes scared you?" a creepy voice came out but at the same time I sounded familiar.

I looked up and to a figure with long black hair, pale skin, and yellow eyes with a slit in the middle. He was wearing a green vest with dark blue under it and sandle.

" Orochimaru" the word accidentally slipped out of my mouth.

"Finally dropping the - sama, Kaito-kun?" Orochimaru chuckled a bit and walked away before saying. "you must be hungry. Get something to eat first. Come to the lab when you're done."

Did I somehow got transported to Naruto? I don't remember much a bout the anime but I do remember some major plots so that'll do. Orochimaru's still in his Konoha jonin vest, I'm guessing he hasn't defected. Which time line am I in? I don't know, I need to see a calander to be sure. But if I remember correctly, orochimaru defected after Naruto was born. So, I'm gonna go with that maybe I'm somewhere around the 3rd Shinobi war.

Since I don't know anything about this body, I'll just say I have amnesia so something. I head towards where Orochimaru is, still wondering where the snakes went. Genjutsu?

I finally reach a door. I went in and saw Orochimaru reading a scroll. "What for a while, I'll be done in a minute", he said. I took a seat at the couch.

(A/N : I don't know what Orochimaru's lab looks like, so just assume it's the lab where Anko asked about the snake skin.)

After a few minutes of silence, " I've decided to start your ninja training like you requested" Orochimaru said.

Ninja training? That's good for me but it's better to get information. "I'm sorry, but who are you? Where here are we? I don't remember anything."

"hmm. That's trouble some. It seems your 'tantrum' caused you to lose your memories." he said then scanned me from top to bottom before continuing, "it doesn't matter. A 5 years old boy wouldn't have anything important to remember anyway."

"let's start here. Your Name is Sentsuki Kaito. Your mother died after giving birth while your father died on a mission when you were two, making you an orphan. I adopted you as the dying wish for your father, a..... friend of mine." he said

So that's my story, but I don't think you should be telling that to a child so early. Well, he is Orochimaru I guess. There was also a pause before saying friend, meaning there's more to it.

" Yesterday, you asked to start your ninja training but I rejected it, saying you weren't ready. Then, you tried to prove me wrong by using a jutsu but eventually failed while using all your chakara. That's how you lose consciousness and gave you amnesia. I was impressed by your efforts and decided to teach you. "

"okay, but what's ninja training." I asked thing it would be weird to know what a Ninja is if I have amnesia.

"Ninja or Shinobi, are the primary focus and the main military power in the series. A female ninja is known as a kunoichi. Most come from a hidden village, of which some come from specialised ninja clans, and will perform missions for a fee. These missions can include: doing manual labour, acting as escorts, gathering secret information, retrieving stolen items, carrying out assassinations, etc. In times of war, ninja will come together to defend their villages and land. The clearest characteristic of a shinobi is their ability to manipulate chakra to create and use techniques. Shinobi are expected to be loyal to their villages for life, and any defectors are considered to be missing-nin, and will be marked for death."he explained (from Fandom)

" and what's chakara? "asking again for the same reason.

" chakra is a form of life energy that all individuals produce to some degree; those who run out of chakra will die. Produced within and manipulated by organs such as the heart, the energy circulates throughout the body in a network called the "Chakara Pathway System", which is similar to the cardiovascular system. Groups such as shinobi have learned to generate more chakra and release it outside their bodies through pressure points called tenketsu in order to perform jutsu

Chakra is created when two more primal energies, known collectively as one's "stamina", are moulded together. Physical energy is collected from each of the body's cells and can be increased through training, stimulants, and exercise. Spiritual energy is derived from the mind's consciousness and can be increased through studying, meditation, and experience. These two energies becoming more powerful will in turn make the created chakra more powerful. Therefore, practising a technique repeatedly will build up experience, increasing one's spiritual energy, and thus allowing more chakra to be created. As a result, the ninja is able to do that same technique with more power. This same cycle applies for physical energy, except the ninja needs to increase their endurance instead. Some unique individual have substantial potential that enables them to exponentially increase their chakra reserves in a relatively short amount of time." he explains (from Fandom)

I asked him a couple more questions (not important). The told me my training would start tomorrow and I should rest today. He then when back to work.
