Rosario to Vampire, Ichiban Ushiro no Daimaou Recommendations
Both have a supernatural school setting with plenty of cute girls and fan service.
Both titles are ecchi-harem type and contain characters with magic powers.
Magical harem hijinks at a school where there's a surprising lack of supervision.
They are almost completely the same...The characters are quite similiar as well, although Akuto in Ichiban seems to be more powerful. There are the main female protagonists, Keena and Moka who both seem fun-spirited and don't seem to worry too much. Kurumu or Ruby from Rosario could stand for Etou in Ichiban. They are both sexy, daring and almost act evil-like but infact, harmless. Junko from Ichiban is most like the vampire side of Moka in Rosario, because they are both strong-willed and serious. Mizore from Rosario is most like Korone from Ichiban. They rarely show emotions and are simple and talk similiar. Yukari from
Magic and mosters along with harem and ecchi. Simple as that.
