Naota was having an ordinary day, until some girl on a vespa bashed him in the head with a guitar. From that point on, his life would never be the same. Haruko is always in his face, Mamimi won’t go away and a robot that came out of his head is cooking for his family. Fellow classmates Masashi and Gaku make fun of his relationship with Mamimi by calling her Naota’s wife. He and class president Ninamori both have a lot in common since they both have N.O. portals opened inside of their heads. Naota doesn’t get along with his father, but he seems to have a good relationship with his grandfather.
Naota aspires to be like his brother, and wants to play baseball. He practices swinging the bat and playing catch, but he just doesn’t have the skill for it. Naota can control Canti whenever he is eaten.
