@Markgraf: It would be quite nice, but don't forget that there is already Katou (the girl with glasses and who's gimmick is shogi) who's in love with Katai, and that she already have some moment (nothing really serious unfortunatly) with him.
I love the idea of Manbagi getting her own love interest, but I don't think it will be our lovely Katai.
About the chapter.... Damn, Tadano's psychic power are sharp as ever. Also, the Katai family is best family.
On another subject, I really like the little characterisation of Manbagi loving horror movie, it's quite nice.
And, finally, Najimi, you sneaky little shit, you just wanted to fuck with everyone ,hu?
