Izuku's Brother?

Tenko

~~~ The Next Day ~~~

"Hey, Isoya." Izuku asked at lunch.
"Hm?" Isoya hummed.
"If you were raised by the Villains, wouldn't they have trained you to be like them?"
"They tried. And, while I can see where they come from, it was a rather sheltered life. I never had an experience where I could hate heroes."

"What do you mean, you can see where they come from?!" Katsuki yelled, just half a table away. Isoya sighed, and got up to walk over to Katsuki. "I mean, there's a fine line between a hero and a villain. You already dance along it based entirely on how people see you. Let's take Tomura, for example. His dad would beat him for wanting to be a hero. When Tomura accidentally killed his family, via a late quirk appearance, he was left on the streets.

"No one would help him because of they believed the heroes would step in and do something. But they never did." Isoya said, glaring down at Katsuki. Everyone at the table was silent. Isoya turned and silently stormed out of the cafeteria.

"If you only have those two, you're not going to get very far." Ectoplasm's clone said. Isoya growled and lunged punching it in its jaw. "I can get far without relying on my quirk! If I have to face my father, he can take it from me! I can't allow myself to become complacent just because I'm safe!" He yelled, stopping and resuming time again and again as he attacked. To anyone watching, it looked like the clone was being beaten by nothing. Isoya had practically disappeared in time.

Isoya pinned the clone. "I will not fail at this. I can't fail this. I have to be stronger. I have to be faster. I have no choice but to be as strong and fast as possible. If I'm not, I will die. He will kill me." Isoya's eyes we're wild, time was flickering around him, going into the past, the future, and even into other timelines. Suddenly, everything stopped, his eyes were back to being grey blue.

Isoya sat on his bed, reliving memories. The experimental enhancements, being chained to the wall, the rigorous training against Shigaraki and the others, being found after Katsuki's rescue, everything was becoming too much. Compared to the LOV, UA was nothing when it came to physical exertion. The tests and classroom activities were a different story. Being social isn't taught in the League. The only person Isoya got close to other than Izuku is Kaminari. The cute electric boy had somehow managed to get past all the walls and defenses that Isoya puts up. It was strange and new to the poor boy.

~~~

The next day Kaminari approached Isoya. "Hey, Iza!" He said, slinging an arm around Isoya's shoulders. "Hey, Kami." The boy responded, still drawing his costume. "This looks really cool so far." Kaminari said.
"It looks simple, but it's kind of complicated, isn't it?"
"Yeah. The goggles are one way and made of Plexiglas. Tough, but light. It hides my eyes, the sleeves and pants are made from the same stuff as Aizawa's scarf, since traveling through time can end with clothes being torn, or even just lost in the timelines. I based the design off of the female Arabic clothes, but there's big differences, like the chest and stomach pieces, titanium, the pants have pockets in hidden in the folds, and can carry anything needed, or will, after I manipulate the material. Basically, infinite pockets." Isoya explained.

"Dude, that's awesome!" Kirishima interrupted. Isoya jumped, looking up at the red head. "Thanks..." Isoya said quietly. "It's no problem, bro!" Kirishima said, loudly. Isoya looked down and to the side. "I have to go. I have to go check in on the café." Isoya said. "Could I come with you?" Kaminari quickly asked. "I'd like that." Isoya said, smiling softly.

~~~

"Hey Isoya!"
"Hi!"
"Hello boss."

"Dude, you're popular here." Kaminari said, looking at the wallpapers and different plants. The workers were dressed in different colored polos and had different pins on their shirts. "Well, I own the place. I like to keep this place running as smoothly and as comfortably as possible." Isoya said, smiling and waving at the different people.

"Hey, boss, uhm... The coffee and hot chocolate dispensers are out." One the employees wearing a light blue shirt and white shorts said. "Ah, thank you. I'll fix that right away. Kaminari, go ahead and order whatever you want, it'll be on me." Isoya said, eyes starting to glow as he walked into the back.

"What can The Lazy Day Café do for you today sir?" A guy in a dark blue shirt said. "Um, I'll try the Special today, I guess." Kaminari said awkwardly.
"Alright, today is the create-a-crepe." The guy in the light blue polo said. "It comes with your choice of tea, hit chocolate, or coffee."

"Alright, that's fixed." Isoya said, coming out with some brown stains on his shirt. "Had to fight with it, but it's fixed." He said.
"You're the best, boss!"
"No, not really. Plus, it was just clogged."

*BREAKING NEWS*
"This just in, a UA student is apparently helping the LOV at this very moment. The LOV is robbing a bank at this very moment. Reports say that there are a total of three people involved in the robbery. Tomura Shigaraki, Dabi, and one Isoya Shigaraki." The T.V. in the corner announced. Isoya shook his head. "Idiots." He muttered.
"The Pro heros are on their way to the scene." The reporter said.

"Let's go watch, Kami. It'll give them something to really report." Isoya said, grinning at Kaminari. "That's a preposterous date idea."
"I-It's not a date!" Isoya said, turning bright red.

~~~

"Isoya! I'm disappointed in you! Pro hero Aizawa said. "Twice!" A voice yelled. Everyone turned to see Isoya, eyes glowing purple and hovering. "Isoya?!" Aizawa asked.
"Twice, show yourself, now!" Isoya yelled. Another Isoya came strutting out of the bank. "Oh, you're here? We hoped you'd be holed up in UA like a good little rat."

"Now why would you think that? I don't work for or with you guys. I understand all your back stories better than you think. Where is Twice?" The real Isoya asked. A loud thud was heard as Tomura stepped out of the bank. "Ah, Te-Tomura. I didn't think you'd be this stupid. Kurogiri must be on stand by, right?"

"I wonder what Nana would say, seeing you do this."
"Don't you dare bring her into this!" Tenko yelled.
"Oh? Did I strike a nerve there? You wanted to be a hero once, right?"

"Shut up!"
"No. You wanted to be a hero, Tenko! You wanted to be just like your grandmother!"
"Shut up. Shut up!" Tenko lunged towards Isoya.
"Tenko, please. Just listen."
"No! They corrupted you! Made you just like them! You used to be like us! " Tenko yelled, reaching out. Isoya stepped to the side.

"There is no them and us! Tell me, Tenko, what's the difference between you and them?! There is none! It depends on who tells the story, Tenko! It depends on what people think! You could be a great hero! Please! Just... Please listen to me." Isoya said, hugging Tenko.

"What happened to you hating me? Tenko asked softly. " Tenko, I never hated you, I hated what happened to the kid I used to know. To the boy who would have done whatever it took to be the hero. I hated what my father did to you. You have the power to choose who you want to be." Isoya said, hugging Tenko tighter. He gently held onto Isoya, four of his fingers gripping Isoya's shirt. "I can't. I'm sorry." He put his last fingers down, about to disintegrate Isoya.

Nothing happened other than Isoya being shocked that Tenko would try to kill him. "Why, Tenko?"
