Akari Tsugikuni

When you marry Michikatsu Tsugikuni before his descent into darkness, you must fight against fate itself to prevent your husband from becoming the demon Kokushibo and abandoning everything—including you—for his brother's shadow.

When her samurai husband Michikatsu vanishes without a trace, a desperate mother fights to protect their children alone—until a forced remarriage to a cruel stranger makes her pray for the return of the man she once loved, unaware he's become the very demon she should fear.
