Hidarime Tantei Eye

The series is really twisted!!!

Yumehito, a super good brother turned out to be bad...
Ainosuke, a loving younger brother that got a super eye and now fighting his aniki...
Hitomi, a school nurse who has so much debt...

Yumehito telling Ainosuke to kill him if he wants to stop him from his criminal acts.
Ainosuke, being torn apart because he can't decide of what to do. He wanted to like, kill, his aniki and yet he wanted to save his aniki and be back to their used to be normal happy lives...

In chapter 4... Noriko asked Yumehito if it is okay to kill Ainosuke there, in the Blue Heaven concert, too. And Yumehito told her it is okay since it's Yumehito whom she really actually wants to kill... Then in the last part, the one where Ainosuke lost control of himself, tried to stab his aniki at his side... Yumehito made 'iwas' and told him, if Ainosuke really wanted to kill him, the knife should be stabbed in his neck or somewhere there...

I just came into the conclusion that... maybe... Yumehito just had no choice... like he was controlled and deep inside, he was just pretending that he doesn't care about Ainosuke anymore just so that he could protect his life... like he sacrificed himself of being a villain to Ainosuke's eyes to protect him from Noriko. He knows his brother could survive without him at least so in the special, he was supposed to be dead, unfortunately, Ainosuke found it out. That's why he gave his eyes to Ainosuke, even though it was just an experiment and he didn't know it would be like a super eye to Ainosuke. He thought him all the tricks to find all the elements in the crimes and he has to pretend that he was a super villain. Coz if he will not do it, Ainosuke would end up dead. And he's willing to die in place of his brother. But it just got complicated because Ainosuke found out everything....

ughhhhhhhhhhhh! I can't figure it out!!!!
