requested by EhLevi

while overhaul awaited the appearance of his little brother

he thought to himself what the two could do together

they were unable to simply roam the halls of the Shie Hissikai building anymore

with it now being destroyed and them retreating to a backup base in the forest

he had just managed to escape after the fight with that deku kid and away from the League of villains who wished to kill him

not that he wanted to

he preferred treating his baby brother to a full day out where he could spoil him

Kai doesn't value humans

he views people as pawns for their utilitarian value and being willing to experiment on them to accomplish his objectives

He carries this sentiment even towards the other members of the organization he has dedicating himself to since childhood, treating them as expendable sacrifices for his well-being and having no qualms in killing them off for the smallest mistakes

but tokoyami was different

he was his blood, even if their father was different they came from the same womb

the one exception to the rest of the world

the only human that he felt comfort in

he shared his ideas of quirks, and even though he was cursed like his older brother

he used his quirk to better the world

while he kept up the appearance of a U.A student that wishes to become a hero

the child was a medical and psychosocial prodigy

able to create serums that would benefit the world to rid it of quirks once and for all

as well as getting anyone he meets to trust him

bringing more desperate filth with somewhat disgustingly effective quirks that will better the cause

even at the age of 4 when his disgusting quirk began to form he was able to lure people in

it wasn't that his brother was disgusting, it was just his quirk

once the two rid the world of them, they would get rid of their quirks to create perfect harmony

"Chisake" a familiar voice called out

his little brother, fumikage tokoyami was making his way up to meet him

everything looked the same appearance-wise to the rest of his worlds except for longer feathers that flowed almost as tall as his big brother

this was a way he wouldn't be recognised as easily to the public

"ah fumikage, you finally decided to come" overhaul joked

fumikage stopped just outside his comfort zone, knowing his brother was the biggest germaphobe in the world and did not wish to make him uncomfortable

that was one of the reasons they were going out

because Chisake was unable to hug his brother he instead treated his brothers to days out

buying whatever the little raven decided

"so, how is the drug coming along?" overhaul asked as the two passed an ice cream van in the park

clean fresh air and since the park was empty meant fewer opportunities for them to be recognised

overhaul hiding behind a tree as tokoyami bought himself an ice cream with his big brother's money

they always started small

"It is coming along well, Eri still believes I'm treating her wounds, which I am, I'm no liar, but I do take what I need to finish the drugs" tokoyami explained

since eri was the granddaughter of the Shie Hassaikai's boss with a rare type of quirk that enabled them to make the world a better place kai simply felt obligated to treat her with as little kindness he was able to find in his heart

meanwhile, tokoyami had been able to build trust with the little girl, he was never the one to cut her open, in her eyes he was the only one that really cared for her, the only one who asked her how she was doing physically, mentally and emotionally, being the only one there to help her develop her social and intellectual development

tokoyami had been with her so long that he actually cared for the brat and visa versa, believing the raven was also being held hostage due to his worth at the Hassaikai's operation

when Eri had seen tokoyami again in U.A she instantly clung onto him

tokoyami had instructed her not to say what their relationship was because he said he wished for neither of them to remember what happened to them

to which the little girl understood and never mentioned their connection to anyone

these small things his little brother was able to accomplish, even with being so young, amazing overhaul

proud to share the same blood as one another

and the main reason why the masks are worn by his closest subordinates and himself were the representation of a birds beak

it was to show how important tokoyami was to him

the only other person he'd ever want to share the same air as him

the first and only person he'd want at his side

he loved his brother in his own way

and god forbid if anything ever happened to him

he wouldn't be afraid to get his hands dirty
