The Constellation Nerdulus: an adventure in the otaku galaxy is a Role-Playing video game that was developed by Advance Communications and published by M&M for the Famicom in 1991.

The game is a combination of science fiction and comedy in which a nameless hero arrives in a city where women have stolen the rights of men. The player controls the man as he tries to free men in the city. Otaku no Seiza features turn-based battles, similar to the Dragon Quest series.
