'Brother, I don't understand this'
It's been three years since Tomura died and he reads some of the stuff on his older brothers computer. He doesn't like what he finds.
'You're changing'
There were war plans on this computer, plans for gaining allies and... taking over Japan? Maybe, Yoichi doesn't know, but either way, he doesn't understand why.
'I can't stand it'
He wants to talk about this, but at the same time he doesn't want Katsumi to know that he knows.
He tells this to an online friend instead.
'My heart can't take this damage.'
Katsumi has been out of the house, even in the early hours of the night and sometimes late afternoon, and Yoichi doesn't know why.
He knows it's about the war plans on his computer. He's also read some of his speeches, speeches the man as written to get people on his side. His brother is definitely changing.
'And the way I feel, can't stand it.'
He reads about a vault... huh? For what? He doesn't know, the plan is either unfinished or he decided to keep the rest in paper form and bring it with him. As if he somehow knows Yoichi has been sneaking into his room...
'Hmm, Brother I don't understand this.'
He has found out... how? Yoichi doesn't know, but he knows and he told him to stay out of his room, does he? Yes... for a couple weeks.
'You're changing, I can't stand it.'
Yoichi's gotten to sick to snoop into Katsumi's room at night... but he really wants to know what's happening...
'My heart can't take this damage.'
After about a week of this sickness, Yoichi wants to go out and do stuff, but Katsumi insists he stay inside, so he doesn't 'get worse or infect anyone else,'
Yea, he doesn't want to make anyone else sick, but that's what masks are for, and he can't really get worse then he is now.
'And the way I feel, can't stand it.'
He tries to sneak out one night while his brother is out, but he doesn't get to far before a coughng fit overtakes him, and he sure it hasn't been a few hours when Katsumi comes back and picks him up and carries him inside, "I told you to stay inside." His older brother had told him
"Y-yea," he coughs, "but I swear i-it wasn't that bad when I was inside..."
"Going outside makes it worse for you." Katsumi said before laying him on his bed, "now stay here, alright little brother?"
"Fine..."
"Good."
'Hmm, brother I don't understand it.'
It was a few weeks later when he next tried to sneak out, he got further and was proud, but then the same thing happened.
"I told you," his brother sighed, "you can't go outside."
"Uhg..." Yoichi coughed
"Stay here and you'll get better faster."
"I've been sick and in here f- *cough* for a month... Do you really think I'll get better?"
"Yes,"
"Fine, whatever you say.."
"Good," Katsumi ruffles his hair like he used to, "now, rest and I'll bring you something to eat tomorrow morning."
'Bro you're making it hard for me.'
It had once again been a few weeks and Yoichi tries to escape again, actually this is is second time in the last two weeks.
"If you don't stop trying to leave, I'll have to use drastic measures..." Katsumi said, " you can't keep doing this, it really worries me, little brother."
"Wha- *cough* what do you mean, dra- *cough* drastic measures?"
"Bars on your windows... and an outside lock on your door...:"
"N-no that's t-to far... p-please don't..."
"I won't if you stop trying to leave." Katsumi once again laid him on his bed, "I love you baby brother... you know that, right?"
"Y-yea... I love you to Ka-Katsu..."
"And you know I'm just doing this to keep you safe tight?"
"Y-yea..." He says even though it feels more controlling then anything.
"Good," his older brother says, before tucking the blanket over him and leaving, sgutting the door behind him.
'Bro, you're making it hard for me.'
After a few months and four more escape attempts the bars were added to the windows
'Bro you're making it hard for me, uhhh.'
After one more attempt the lock was added to his bedroom door, with a key for the inside instead f the outside and Katsumi kept the key...
'Bro you're making it hard for me.'
He was to weak to break the bars on his window but he could pick the lock on his bedroom door. He was able to get out and get way further before doubling over in a coughing fit.
He heard a sigh behind him, "how did you get out this time?" He heard before he felt the strong arms of his older brother picking him up.
"I-I picked the l-lock..." He mumbled as he snuggled into his brothers warm chest, "I-I'm sorry b-big brother..."
"It's okay, Yoi, but if you do that again I'll have to bring you somewhere more secure.."
"Wh-where?"
"I hope you don't have to find out..." He lays him on his bed and tucks him in, "I love you, baby brother, good night."
"Night, big brother... love you too.."
'Bro, you're making it hard for me.'
After a few more escape attempts Katsumi had decided to bring him to that 'secure place' he mentioned, it was... a vault.
"B-big brother this is... a bit to far..." he mumbled
"No... this is the safest option for you now..."
"B-but, Katsu..."
"No buts, baby brother I'm doing this because I love you..."
"I-I love you too but..." the vault door was shut before he could finish.
'Bro, you're making it hard for me.'
Yoichi coughed and curled up on the floor, sure his brother had put a bed in here, but he didn't wanna get up... if he couldn't escape there was no reason to get up.
'Hmm. Brother I don't understand this.'
His brother had given him a plate of food to eat... he started eating it but it made him feel worse... He didn't understand why his big brother was doing this...
'You're changing I can't stand this,'
"You know this is to protect you... you can't go out, I told you this many times... I'm helping you." His brother said.
"No..." He coughed, "no this isn't helping, not really... you say it is and maybe you actually think it is... but this... this isn't right, you're changing... I can see it."
"You'll see, little brother, that this is for your own good,"
'My heart can't take this damage.'
Deep down he knew... this wasn't his brother anymore but he still calls him ;big brother' maybe he's delusional...
'And the way I feel, can't stand it.'
He was sick, it felt so terrible, yet he refused to eat the food Kat- All For One gave him, refused to take the medicine as well... He would die before he ate anything the man gave him.
He hated it, hated being sick, hated that he still loved him...
'Hmm, brother I don't understand this.
'You're changing I can't stand it.'
He's going to give him a meta power... someone told him, someone the man seemed to trust enough to tell him secrets but someone who wanted to take him down, Genji Izumi... He hopes he meets him again.
'My heart can't take this damage.
And the way I feel, can't stand it.'
His brother gives him a meta power and without him knowing at the time it merges with one that he has always had, without knowing and he now stands up to his brother.
'Hmm, brother I don't understand this.
You're changing I can't stand it.
My heart can't take this damage.
And the way I feel, can't stand it.'
It's been a few years and Yoichi has been saved, he fell in love with one of his saviours... He still doesn't understand why Katsumi has become a monster but still. he's much happier now.
'Hmm, Brother, I don't understand it.'
He's dead and alive at the same time and he has someone he can help protect again, after 200 years... Izuku Midoriya aka the reincarnation of his twin, Tomura, and he knows this time, there will be no vault. Just a battle.
