Seiya Nakano

Shunsuke, orphaned as a child, is a pessimistic young man. One day, drawn to a mysterious song next door, he meets Setsu, an older woman.

Unable to recover from her lover’s death, heartsick Satsuki becomes drawn to the Moonlight Shadow event, rumored to unite the living with the dead.

As the Saika family's reputation wanes, the son is tasked with assassinating shogun candidate Yoshimitsu of the Kishu Tokugawa clan.
