Sakuya and Aine's son, Shion makes an appearance in the final chapter of Kaikan Phrase as well as in a special side story from Love Celeb, another work by Mayu Shinjou.
Shion resides in New York City with his parents and is characterized as a bright child who has a fondness for reading books. As mentioned in the Love Celeb side story, he is attending kindergarten and possesses an awareness of his parents' intimate activities, even commenting that his father is too rough with his mother to the point of making her cry. Shion firmly believes in always being gentle with girls, a principle his father frequently reinforces.
