Anima-Machine + System

A man with chocolate brown hair and light amber eyes was about to cross the street, all the while eating some ice cream.

- BANG!! -

All of the sudden, a massive truck appeared and easily struck a man, obliterating his body into pieces...

And then it just left...

-

"And now since I'm a higher god I normally would have given you three wishes but since I am 'better' I can give you five, which I will."

Looking at the god-like entity which took it a vessel made out of black fog inside of the infinite abyss of whiteness ( pause? ), Shiro contemplated his choices.

Shiro was it married and didn't have any sort of kids, however unlike most reincarnators he actually got a job!

"Hmm...First, it's quite obvious that I want some system that would allow me to level up ( specifically one with a shop and things similar to the solo leveling system )."

"Second off, find it an underrated idea that most people ( In novels ), Don't try to obtain some sort of nanobots... Specifically ones with :

Automatic regeneration ( constantly allows for my body to regenerate when injured )

Illusionary resistance ( potent resistance against any sort of mind affecting or illusion ability )

Body tethering ( The power to manipulate and shift the body constantly to allow it to grow in strength exponentially, along with an increase in potential )

Weapon creation ( otherwise seen as an infinite amount of nanobots that can be used to create weapons and armor - etc - )

Energy creation ( a potent ability that allows for the user to create and manipulate energy with properties similar to Ki and Mana - or something - )

Data storage ( this ability allows for the user to obtain data on ANYTHING That is seen - from abilities to techniques -, stored inside of an infinite data space so that such information can be applied to abilities )

Gene creation ( The power to replicate and create genes to add to the body over time, sort of an application of body tethering )

Omniscience ( I would want as close as anything to Omni science that I can get, or just having A LOT of information inside of data storage already )

Quantum / physical body ( overtime after obtaining the Nanobots, My body would slowly turn into a quantum form that still retains its physical appearance, allowing for greater energy manipulation and such )."

"That's technically a lot of wishes stored inside of one but it doesn't cross the boundaries, So I will let it slide."

'Great!'

"Third of all, I wish that I could have something known as the [ boundary system ], technically a subsystem of the system I would already have. This would allow me to cross the boundaries of worlds and traverse between them all the while carrying multiple power systems ( I might be able to do that since I already have the Nanobots, but I got to be sure )

"Fourth, I wish my body would have the highest compatibility rate with the nano machines as possible, allowing me to use all of its features off the bat ( preferably if I would already have an adult body )."

"And finally at last, You think you could probably trick me... I wish for all of the features of the native machines to be at the best level you could ever create ( Even if it uses your lifespan to do so! )."

"Smart... I would have given you all of the abilities but simply add a rudimentary level, but now I got to make them at the peak... Well I have infinite lifespan so it doesn't really matter anyways, so bye-bye!" Said The mysterious entity, waving Shiro away.

-

"Haah!?"

In the middle of a large forest, a man with a decently good body ( seemingly mystic amber eyes and black hair ), startled by his own appearance.

"... Seeing as how I wished for the nanobots to automatically appear within me, it's probably why I'm decently calm right now." Said Shiro, turning his head around.

[ Activating system.... Balancing out with animachines... The fusion with the system and the animamachines has created the 'Anima System'! ]

'So the Nanobot was called the 'Animamachine', and it fused with the system...neat.'

[Correct host. I'm the fusion of the system you had previously and the nanobots, allowing for me to become a much higher level creation then expected along with being a mysterious fusion to even the entity that created me]

'I see. Then I'm just going to call you Anima.'

[Registering name... Complete.]

'Ok then Anima, it's quite obvious that I'm in some sort of fictional world. Can you tell me which world I am inside of?' thought Shiro.

[Calculating answer... The most likely hypothesis would be demon slayer or some sort of alternate timeline / universe, specifically due to the existence of higher level beings and a new energy coexisting with the original demon Slayer world.]

'Ok... Wait a second it's night time!' thought Shiro, turning his thoughts away from the system, worrying about how he could encounter a demon.

[No problem host. Would you like me to open the starter system package?]

'definitely!'

[ The starter system package includes :

- Nanomancer Class ( MAX )

- Dimensional crafter Subclass

- Dungeon Run ( skill )

- Nanobots activation ]

As Shiro processed the information that flowed slowly inside of his head, he quickly felt what he thought was a million ants crawling all over him, being a ticklish and yet horrifying experience... Also due to the nanobots, He did not scream and felt as the nanobots fused with his body ( From now on I will just call it 'Nano' ).

[Detecting mysterious energy, would you like to absorb carefully or fast?]

'Carefully, also do you have it inside of your database?' Asked Shiro, as he continued to look at his surroundings with his 'reforged' body, which at the start felt stronger than his regular body before he got reincarnated, but now it was a whole another level!

[I In fact do]

[Primary ( energy ) :

Primary is an energy located inside of a demon slayer alternate timeline / universe, created from the mystical white spider Lily that appeared on the moon generating such a large amount of energy that at some point it landed on the surface of the Earth which humans slowly absorbed and turned into supernatural abilities contained through 'breathing techniques', allowing for them to fight against the demons who also held the natural ability to manipulate primary through the usage of the life force that they harvested through humans.]

"Ok. How's the absorption process going?" Said Shiro, holding new found confidence that allowed him to actually speak aloud.

[I'm the highest tier nano machine forged with the fraction of a soul of One of the strongest beings in the entirety of all Omni versus... It's been absorbed]

"Why didn't you tell me? Well anyways since you're a system I have to have a status. So can you show me one?"

---STATUS---

NAME : Shiro Hatsu

AGE : 26 ( PREVIOUS ) -> 17

SEXUALITY : Male

CLASS : Nanomancer

Subclass : Dimension-Crafter

NANO INFUSION LEVEL - 0.1

LEVEL - 1

----STATUS---

"No skills?"

[I didn't find the need to mention them inside of the status, plus you would need to look inside the database for those.]

"Yea, your right. But is the nano infusion level me becoming more quantum?" Said Shiro.

[Correct. By the estimated time of you traveling to another world, It should be 100% meaning that most if not all of your body would have been termed quantum physical, basically meaning you have the effects of a logia user for OP just without the Haki weakness.]

"Ok then. Time to travel to a village then."
