Random non-serious question.
Even though I don't like Byodoin, I'd pick him. Just because his personality. I have a feeling he's the type of no nonsense brother who will bully every guy who gets close to his sister. Pretty sure Oni would do something similar.
I would like to play execution game with him.
Duke would be another interesting choice. Duke Homerun annoying people.
Another reason for Oni being a cool brother, he can make stuffed animals XD
Kimijima. I'd love to have a big bro that has a lot of moneyz and can convince anyone of doing anything.
The one I'd like the least would be Tanegashima, he sounds like a total douche of a big brother
Oni and Togukawa looks like they both will be cool to have as an older brother.
But I finish college now. Just that I can't convince myself Oni is actually younger than me.
@ Hardy: Tanegashima seems so laid back and carefree. Doesn't sound like he'd make a great bro. Just let everything/anything happen.
I said it mostly because he stole Kaidoh's and Sanada's water just to piss them off
