Chou Hatsumei BOY Kanipan

The story revolves around Kanipan aiming to be the best inventor and his adventures while trying to accomplish this.

Kouta, a country boy who lives with his grandfather, is now moving to the city to attend high school. Changes come with his new home and new school, but nothing could have prepared the gentle young man for girls, specifically a bombshell fox spirit named Chizuru. As if her aggressive advances weren't enough, he also catches the attention of a frosty wolf spirit named Nozomu. Kouta is dragged into supernatural events as a result of his contact with the two girls, and his school life only gets more chaotic by the day. But with a girl who gives "foxy" new meaning and another howling after him, things are looking up for his love life.

In the future, personal computers have developed into "Persocoms", mobile computers that look like human beings. Hideki Motosuwa, a prep school student, desperately wants to buy a Persocom but cannot afford to. One day he finds a Persocom that has been thrown away and decides to keep it. When he turns on the Persocom, all she can say is "Chii" so he decides to name her that. After a while it starts to become apparent that Chii is more than an average Persocom. Having much better performance, it seems that Chii might be a "Chobit", a type of advanced Persocom rumored to have independent thought.

Sunao Moriyama finds a strange but cute creature that he names Potemayo. Potemayo starts following him everywhere, usually riding on top of his head. His discovery becomes the center of attention in his class at school. Soon after, a similar creature appears, and is named Guchuko by one of Sunao's classmates. However, Guchuko doesn't seem to be as good-natured as Potemayo.
