Kiyoshi groaned as he woke up. He heard Katsuki mumble something before hearing him shift below him. He just rolled his eyes before climbing down from his bunk and out of the room and into the bathroom. Kiyoshi looked at his roots that were showing before sighing. Kiyoshi was a brunette but he recently dyed his hair blonde for a prank. He didn't mind the blonde he just looked like an almost carbon copy of Katsuki now. He scratched his belly before going to the bathroom, washing his hands, and then brushing his teeth. He yawned as he walked downstairs and into the kitchen. He opened the fridge before grabbing a banana that was for some reason in the fridge. 

As he was eating it, he turned on the TV that was on the news and they were talking about the newbie hero "Bang". Apparently, the hero had a unique quirk that allowed him to temporarily stun Villains and AI into submission. He made a quick mental note to research the hero before changing the channel. He saw nothing he liked so he went to Netflix and choose an old anime called "Kimestu no Yaiba", it wasn't as old as the ones he used to watch like Naruto or Inuyasha but he saw good reviews about it. (A/N: keep in mind that BNHA takes place in the future so stuff that is relatively new to us is not new to them. Please no hate) He got to the second episode before Katsuki walked down the stairs with a towel on his head. 

"The fuck you watching?" He asked before walking into the kitchen. 

"Kimestu no Yaiba" Kiyoshi replied before clicking off Netflix and going back to the news where Pro hero, Hawks was being filmed while he fought a Villain. Katsuki walked out of the kitchen before asking,

"Do you want grilled fish or onsen tamago" 

"Do we have rice?" 

"I don't fucking know," Katsuki said before walking back into the kitchen then yelling out a yea. 

"Onsen Tamago, We ate grilled fish yesterday." Kiyoshi said as he walked into the kitchen "Would you like help?" 

"Fuck no. Last time you cooked you set our house on fire. Now get out of the damn Kitchen" Katsuki said as he glared at his brother and pushed him out of the kitchen. Kiyoshi just shrugged before walking up the stairs and put on his uniform. He walked down the stairs to see his brother eating. 

"You never wait for me," Kiyoshi said while fake pouting making Katsuki have an irk mark on his head. 

"Shut the fuck up." He grumbled before getting up and cleaning his dish. 

They walked out of the house before Katsuki quickly turned around and ran back into the house. Kiyoshi just stopped and waited slightly curious about what he forgot. Katsuki walked out of the house carrying Kiyoshi's bag. After 3 minutes of getting yelled at, they started walking again. 

Kiyoshi sighed as people parted ways making room for the twins. Boys either glared at them or quivered at the sight of them while Girls either ignored them or stared at them with hearts in their eyes. 


Months went by and Katsuki and him trained more and more. He studied because Katsuki would force him. He ate healthy because Katsuki forced him. He started to wonder if he actually wanted to be a hero or if he was just doing it for Katsuki. He never really cared for being a hero but it's not like he could do anything else with his quirk. Maybe becoming a construction person but that was too boring for him. 

"Oi. Are you going to eat what I made you?" Katsuki asked as he glared at his brother. 

Kiyoshi snapped out of his glance to see that he made Onigiri for him. Kiyoshi immediately had sparkles around him. 

"It's spicy tuna. I know that's your favorite filling." Katsuki grumbled as his brother looked like a kid in a candy shop. Kiyoshi jumped up and tackled Katsuki in a hug making the boy let out a yell in protest.
