Step into the vibrant, yet perilous, world of Mainu, a fast-paced action-adventure game developed by Kanmai. The narrative unfolds within a mysterious 13-floor mall, a place consumed by an unusual energy.

Players take on the role of Tonu, who, after meeting Venera, discovers a startling truth: a powerful being named Ormatsu has inadvertently infused his magic into ordinary capsule toys, bringing them to life as creatures called Mainus.

Ormatsu's influence spreads like a dark force, splitting into thirteen extensions that drain the life from each floor of the mall. Tonu, empowered by his own force energy, gains the ability to control these awakened Mainus.

Guided by Venera, your mission is to collect, master, and strategically unleash the unique powers of these Mainus to combat Ormatsu and prevent the mall, and potentially reality itself, from being consumed.

The gameplay centers on strategic combat and creature collection, blending fast-paced action with puzzle-like elements as you figure out the best Mainus for each situation. The anime-inspired aesthetic and cute creature designs offer a unique visual style, contrasting with the Souls-like combat challenges that await.

Mainu offers a single-player experience with Steam Achievements to unlock and customizable volume controls for a personalized playthrough. The ability to save anytime ensures you can jump back into the action whenever you're ready.

Explore the unique setting, uncover the secrets of the mall, and master the powers of your Mainus in this engaging adventure.
