THE VALIANT MUST FALL, VOLUME 2

Shino wants to end her life, but not before ending her mother's, saving them both from a fate worse than death. However, they are Adashino, immortals who can't be slain by ordinary means. That's why she's enlisted her new kinsmen, former samurai Haruyasu, to steal a Sessho-seki, a blade capable of killing the unkillable.
