Conveniently an Orphan: Downplayed because Aya and Aki's mother is still alive, but her coma and their father's death two episodes earlier puts the twins in this situation, for all effects and purposes.
Does Not Like Men: Ceres is determined in exterminating all men from the Mikage family.
Dude, She's Like in a Coma: Yuuhi tries to kiss a sleeping Aya, but she slapped him in her sleep when turning over.
Family of Choice: Turns out Suzumi and Yuuhi aren't related by blood: Suzumi was married to Yuuhi's older brother, that was killed in a car accident shortly after they got married. As Yuuhi doesn't get along with his father and stepmother, he stayed with his sister in law. When Yuuhi is done telling his story to Aya, he asks her that, if she would like, she can see him and Suzumi as her family, but by that point, Aya is already asleep.
Luminescent Blush: Yuuhi gets one when Suzumi tells him she's proud of him for stopping Ceres and being able to revert her back to Aya, because it reminded him that he kissed Ceres/Aya.
Parental Abandonment: Yuuhi's father seems to not care much about him, prefering his other son that he had with his second wife.
