Damn, aside from Masahiro, who I'll admit is growing on me, all the characters are really damn good.
I appreciate Aki standing up for a girl who's only given him shit in the past on principle, and then going to comfort her despite the shitty way she treated him because he thinks it's the right thing to do and he knows what it's like to be socially ostracized.
Not to mention that him and Iroha have a good chemistry by how they bounce off one another. Really great figures all around.
I still hope Sensei gets more chapters, though...
