Fight with speed, precision, and style. Your skill is the only limit.

Link katana and energy-fist attacks into relentless combo chains, mixing charged strikes, power-up states, grabbing and launching enemies, brutal finishers, devastating special attacks, perfectly timed parries and dashes, and much more.

Weaponize the environment itself: break pillars, smash enemies through obstacles, and turn the arena against them.

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.
