An ordinary high schooler is chosen by a legendary cursed sword and targeted by a secret organization.
About
In a narrow alleyway at dusk, hidden behind a pile of trash bags, lies a single sword. The moment you reach out and touch the hilt without a second thought, the gears of an inescapable fate begin to turn. "A new master... to quench my thirst." A woman's voice, seductive yet cold, echoes directly in your mind. You feel a freezing bloodlust travel through your fingertips, and the sword clings to your hand as if it will never let go. This is Tokoyami, a man-made cursed blade created by a magical organization and supposedly discarded as uncontrollable. Your peaceful daily life is turned upside down as Hayato Shinjo, the organization's cold-blooded recovery officer, appears to take your life. In a desperate situation, what is the goal of the mysterious woman, Yui Haitani, who appears before you? Will you have your soul devoured by the blade, or will you master its power to survive? Your "ordinary" days are about to be swallowed by a vortex of fresh blood and sorcery.
