minori, formerly the software division of CoMixWave, gained independence in 2007. They use Musica as their main engine. A few of their earlier games' opening movies were animated by Makoto Shinkai. Their name is said to be derived from their own catch phrase, "We always keep minority spirit" (though pronunciation is different).

On February 28, 2019 minori announced the cessation of operations.
