About Mainu
Mainu is a fast-paced action adventure set in a mysterious 13-floor mall consumed by energy. You play as Tonu, whose force energy lets him control living creatures called Mainus and fight to stop the powerful being Ormatsu.
The mall and its creatures
Tonu meets Venera, who tells him that Ormatsu unknowingly infused his excess magic into ordinary capsule toys, bringing the Mainus to life. Drawn to the mall’s endless flow of light, food and movement, Ormatsu spreads through the building like a black hole, splitting into thirteen extensions that drain the life from each floor.
Fight back
Guided by Venera, Tonu collects and masters the Mainus, then unleashes their power against Ormatsu. He must stop the being before it consumes the entire mall and reality itself.
