Fuuka
Dafuq? Dude's fucken crying in front of his hot ladyfriend because he's not the best at rock music and can't outdraw a major label band at their first major gig?
I kinda assumed this was leading to Fuuka joining the band but I don't even know now. She's not even doing anything other than hanging out in a special club for Hot Rock Star Girls Who Want Haruna's Dick™, a surprisingly non-exclusive club with 4 current members (and would have had 5 if Fuuka1 was alive to be in it)
UQ Holder
Backstory galore. I have to say the last 20 chapters made me like Tota a lot fucking less. He just seems like an idiot tool who says Negi shit all the time now, except without any of the good parts of Negi. Someone on SA pointed out something funny: there's only 6 people in Negi's class who didn't have Magic powers by the end of the series.
