Karin Maaka is constructed of 95% pure embarrassment. If you have a low tolerance for that most defining of traits of the shy high-schooler, you won't like this. If you don't mind it, and you like romantic comedies with a supernatural theme, this is a good series to read.

I also like that neither female lead (Karin) nor male lead (Kenta) is a loser or an idiot (although both are capable of a lot of idiocy nonetheless, being teenagers in love). They're both responsible young people; Karin is made to pay her own way by her parents, while Kenta keeps a roof over his mother and himself by working extremely hard. No, the difficulties between them are the consequences of crossing between two worlds, of the nature of Karin's physical needs as a vampire, albeit a weird one, and both characters' feeling that they're not good enough for the other and trying to "do the right thing" on a regular basis.

Stories like this live or die on the characters and the reader's ability to empathize with their situations and feel for them, and in this Karin succeeds remarkably well, while the comedy is joyful and keeps the overall feel lighter despite the bittersweet nature of it all.
