12 Beast Graphic Novel Volume 05 (Mature)

"The newest monster girl series from the creator behind the New York Times best seller Monster Musume! There are three things you should know about Touga Eita, second-year high school student and heir to the Touga-style ninjutsu dojo. First, he really, really loves video games. Second, when given a choice between heroics and saving his own skin, he will always choose the latter. Third, he's never so much as kissed a girl! All this changes when a voluptuous girl with wings and taloned feet named Aero appears and calls on Eita to help save her people - the harpies of Re-Verse - from a merciless onslaught of giant robot monsters known as Gigas. Eita will follow his newfound harpy friend into a whole new world, filled with monster girls and fantastical creatures beyond his wildest dreams."
