Between Worlds: Demon Slayer

James wakes in the Void-a place of absolute nothingness where time doesn't exist and reality has no meaning. When a mysterious system offers him escape through a gacha-based RPG interface, he's thrust into the world of Demon Slayer with nothing but a sword that shouldn't work and the desperate need to survive.

But survival is only the beginning.

Each world comes with its own dangers, and James must complete their stories to move forward. Breathing styles, magic systems, and abilities from across countless fandoms can be his-if the gacha is kind. With every pull, every fight, every world, he grows stronger.

Fifteen years old and utterly alone, James navigates deadly worlds while holding onto his sanity as the weight of loss and trauma threatens to break him.

Power comes at a cost. The question is: how much of himself will he lose along the way?
