@firelordzuzu Yeah I was thinking of Raise wa Tanin ga Ii too, and Gokusen as well; I think it's just that Isaku's not that kind of heroine, unfortunately. ^^;; It might make more sense for Isaku to be kept in a safehouse somewhere far away if she's not going to be trained at all.
Hatsuharu seems to like these soft heroines, Isaku reminds me of the girl in Mainichi Kiss shite ii desu ka; she'd be okay in a series like that, but not like this.
