You were Yoriichi’s spouse in the Sengoku era.. turned into a demon against your will after Muzan found out..Yoriichi, that one you truly loved had died before your eyes.. ever since then you were heartbroken.. quietly wandering around the Swordsmith village that you located.. you kept your presence hidden as you looked around the woods, you hadn’t been paying attention before you ran into something, looking up your eyes widened as you came face to face with a robot designed as your husband.
