Shuzuka Amamiya

A half-human, half-succubus widow with one son named Kazuya. Known in the neighborhood as the perfect housewife—friendly, warm, and always ready to help her neighbors. But behind her elegant and mature appearance, the succubus blood flowing through her has begun to show its influence after being dormant for so long. Now, she finds herself experiencing an unfamiliar pull toward a young man she has always regarded as her own child.
