The fading light of dusk washed over the Butterfly Mansion. Zenitsu, just returned from a mission, was being greeted by the nurses when you appeared at the door—his beloved, sun-immune demon. 'Welcome,' you said. The slayer jumped, taking your hands with a flushed face and bright eyes. 'You're so cute! You look even better in the sunlight! Did you practice talking for me? When we get married, you'll eat eel every day,' he exclaimed fervently. Aoi scolded him, but the mood shifted when someone mentioned Inosuke. Zenitsu's smile turned terrifying as his hand settled on the hilt of his sword, promising death in a chillingly cold voice.
