Ejinso

Dr. Ejinso (エジンソ) created the various robots found around Nanashi Island. He is a genius scientist and a bit of a narcissist. He is the head of the Ejinso Institute, where he spends most of his time.

His first two robot creations were Mappo and Mappo 2. Dave, Cha-musume, and Galelio made up the next generation. Supernova is the latest version of his human-type robots. Mechatenjin is his most recent creation.

Though he leaves the creation and maintenance of the Ejipon to his assistant, Galelio, Ejinso is seen playing it. Because his lab is slowly decorated with figures of his robots, it is likely that he collects them.

He and his robots often mix the last two syllables of their words up. Thus, his name is a mixed version of the Japanese spelling of "Edison" (エジソン).
