And all the truth was revealed. The thread of fate drips blood and entangles in his throat, dragging Keisuke into the abyss. The clan-killing treasure sword [Tsuren] is now a blade for fulfilling an abominable love, aiming for the lives of Natsume, Kataha, and Cage. Rebellion or death? In the alternative, the final battle was quietly about to begin. Keisuke, who was bound by Yoshiko Akitsu, and dead leaves, who were despaired by Kiharu. Will the two choose an eternal disconnect or a comeback? The popular series, the dignified final edition!
