^ Yeah, as well IMO in volume 2, Kotori somewhat implies Shidou may be a Lolicon after hearing his reaction to having to kiss Yoshino again and then says that he may go after her(Kotori). Shidou replied he wouldn't, to Kotori gets mad about that.
As well in volume 3, during the first imouto war one of Kotori's comeback is that she unlike Mana, Kotori can marry Shidou.
