In a land of assassins and shifting loyalties, an unwanted lord finds his only hope in a woman he can never truly claim.

The Kiyoshi clan lies in ruin, its last heir, Arata, a young man haunted by his past and ill-prepared for the viper's nest of Kyoto's elite. Surrounded by enemies disguised as allies, he is a pawn in a game of shadows where his every breath is a calculated risk. Yet, in the gilded cage of the pleasure district, he encounters Akari—a courtesan whose piercing gaze sees beyond his title and into his ravaged soul. As their bond deepens amidst whispers of betrayal and the glint of unseen steel, Arata must choose: embrace the duty that demands sacrifice, or fight for a love that could be his ultimate salvation... or his undoing.

Dive into Kizuai: The Blade in Moonlight, where honor clashes with passion, and survival depends on a love as dangerous as it is beautiful.
