So first off, I'd just like everyone to know, that this manga does not contain the ripping of any virgins, LOL. If you were looking for some horrible kinky hentay shit that involves ripping virgins, you're out of luck
But yeah, the title's a huge misnomer, because "reaper" is pronounced the same way (as ripper).

Anyhow, it's about some reaper, who's a virgin at reaping (reaping souls), probably because she gets ridiculously sidetracked instead. It's pretty average as far as manga goes; about as average as it gets I guess? Pretty typical shoujo-esque manga. The outfits actually kinda stand out as somewhat interesting, but yeah, average aside from that.
