When the renowned world warrior Ryu, (from Street Fighter lore) begins to struggle with the darkness inside (The "Satsui no hadou") it attracts the attention of a man who has come to fully accept his own darkness, Kazuya Mishima (Tekken series regular). With the Devil Gene howling inside Ryu's mind, Kazuya attacks, catching him off guard and taking advantage of his battle within. Who will win when these worlds collide?
