[Warning: Book contains sexual content that is not suitable for younger audiences] Three things you should know about Touga Eita, second-hear 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 the 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.
