Einlion
Ya'll act like they *have* to be in a relationship for it to be in the harem genre. All of the mainline harem manga aren't a simultaneous relationship, but a bunch of girls pursuing one man (and usually failing for hundreds of chapters). Just the sheer number of people interested in him, three romantically, and two more sexually, not counting Karin for obvious reasons, is enough to hit the genre tag for sure. Ohta doesn't HAVE a harem, but the story hits the harem genre dead on, whether Ein intends it to or not. I don't mind, I don't care. It's a fanfic, don't like it write your own. I'm just calling it like I see it.
