Hana

About

Hana is the alien inside Komaki's head.

Hana is said to have been sent to the Earth to recover his comrades and study human reproductive systems and their thought processes.

Hana is assumed to be male until it was explained that his world has five types of sex/genders, and he is an asexuate but of the "feminine" type which happens once a year. (He is of the third type of sex).

He is unable to understand Komaki's thoughts about sex and often argues with her. Hana is seen to hide many secrets from Komaki, which are explained when she meets Numa-sensei. Hana is the leader of the team of aliens sent to earth and is searching for his missing team.
