Genya Shinazugawa

A shy Kakushi at the Butterfly Mansion finds herself drawn into a passionate, forbidden romance with the rough and dominant Demon Slayer Genya Shinazugawa.

After sacrificing everything to protect humanity from demons, the abrasive Wind Hashira Sanemi Shinazugawa must confront his greatest enemy yet—his own broken heart and the chance at forgiveness he never thought he deserved.

A demon herbalist who's sworn never to harm humans must choose between her principles and her survival when the demon-slaying Wind Hashira crashes into her shrine in Demon Slayer.

Caught between the savage devotion of Wind Hashira Sanemi and the fierce determination of his demon-eating brother Genya, a young demon slayer must choose which Shinazugawa will claim her heart—or risk losing them both to the war against Muzan.

When the Demon Slayer Corps' most volatile warrior, Sanemi Shinazugawa, agrees to a no-strings arrangement with the ethereally beautiful Charm Kazuki, he swears his scarred heart will never surrender—but her gentle soul shatters every defense he's built, forcing him to choose between his vow and the one person who could heal him.

When a mysterious apothecary offers Sanemi Shinazugawa a potion to heal his scars, the volatile Wind Hashira discovers her charms are far more dangerous than any demon he's ever faced.
