[COMPLETE] Denpa Onna to Seishun Otoko

Makoto Niwa meets his first cousin Erio Tōwa at the house of his aunt Meme Tōwa. He is confused to see Erio when he first moves in because all he thought his aunt lived alone, but he needs a little time to adapt to that and other things he finds. Erio, who claims she is an extraterrestrial lifeform, is no longer enrolled on the register of the school and wears a futon.
