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. Aero revels that she was sent to find him, by his missing brother. Eita will follow his newfound harpy friend into a whole new world, filled with monster girls and fantastical creatures beyond his wildest dreams.Touga Eita (刀牙衛太, Tōga Eita): A teenage boy who just wants to be left alone to play video games.
