Kaito lost everything before he even became a man. His father never returned from war, and his mother’s grief left him alone in the world. At seventeen, he discovers the truth—he was never their real child. Beside him lies a mysterious sword that only he can touch.

The moment he grips its hilt, crimson light burns in his eyes, and visions of unknown figures haunt his heart. Chains within him begin to shatter, and his destiny awakens.

Armed with a cursed blade and a past shrouded in mystery, Kaito sets out on a journey that will test his will, his strength, and the truth of who he really is.
