Vermeil in Gold: Complete Collection/bd

Magic student Alto Goldfield isn't having much luck at summoning, but it's required to advance to the next grade. Then he chances upon an old grimoire and summons a lot more than he anticipated - a very beautiful and naked demon girl named Vermeil! The good news: she's willing to become his familiar! Unfortunately, she also wants to "bond" in another way, live off his mana, and isn't crazy about wearing clothes. This is probably going to get awkward, but in a school where the bullies have dragons, could it hurt to have a familiar who can kick a dragon's tail? Welcome to Demon keeping 101, where, with any luck, Alto will hopefully survive summoning VERMEIL IN GOLD!
