Across a continent divided into three warring nations, a fragile balance endured for centuries; until the discovery of Kosenki, a powerful mineral that propelled technology forward, and accelerated conflict even faster.

You play as Hayato, a battle-worn samurai haunted by the ghosts of his past. Once driven by honor and revenge, he now seeks peace in a world that no longer remembers it… His journey unfolds not only across battlefields, but through trauma, guilt, and memory, as he confronts rival nations and the darkness growing within his own mind.

Through Hayato’s journey, the story explores the true cost of war: the loss of loved ones, addiction, and the lasting psychological scars it leaves behind.

A war outside. A war within.
