The premise of the story had some promise: a lone male able to forge a contract with a spirit which is a feat only ‘pure maidens’ can do.
Then it devolved into what is essentially a trashy harem manga where the one guy has all the girls’ attention. Seriously, this set seems to be one sex scene away from a hentai.
Also, while I’m at it, I hate the lead female character. It’s stories like these that give manga and anime negative stereotypes.
