Who's the one in the top left?
Hmmš¤? looks like that guy can match physical strength to Wakatsuki (rumors says that). And also his hairs and body structure somehow matches to Jun. (For more information about that guy click on photo and zoom it and read above information).
I didn't see anything about superman syndrome or being eastern european on Jun's page though.
No it's not jun I just said that guy matches jun a bit. For ex. His body and hair. It's not Jun that is some unknown guy.
What do you think?
