I get the point of what the MC has "archived"... But it still feels stupid to say that the brother could not make a comeback with time... As he is the geniuses of geniuses. She is guessing the even if his brother looses again and again only cause the MC has the "bloodlust all in" power up his brother can't become like that... Sure. Cause if the best fighter in the world is against a dehydrated crazy guy hmit could not beat him... Cause HE IS CRAZY guys .. Murder power!
I just wanted to say that his arc was shit, the MC already was fighting putting all in even in dreadful situations already. But there is no reason to keep making a fuss. Let's move on... The brought MIU over just for nothing???
