Description

My Classmates Left Me Behind In Another World, And Now I Have To Survive The Colosseum With The Worst Ability Of All turns an isekai adventure into a fight for survival. Developed by RuinHouse, this animated fantasy RPG casts you as an abandoned male protagonist forced into the Colosseum with a seemingly useless ability—and every reason to prove it can keep him alive.

Arena combat drives your journey as you battle opponents, grow stronger, and discover how to make an unlikely power work in your favor. Survival is only part of the story: meeting new characters and recruiting allies adds a relationship-building dimension to your rise through this unfamiliar world.

Unlike the hesitant hero of a typical otherworld adventure, this protagonist actively pursues connections. Gay and trans characters feature in the relationship-focused side of the game, while fantasy, transformation, and romance complement the Colosseum’s combat-centered premise.

Version 0.1 offers an early look at RuinHouse’s blend of arena survival and character-driven encounters. Can the worst ability become the foundation of an unexpected comeback? Download and play My Classmates Left Me Behind In Another World today.
