Shinya Sakaki

As Kanami Ibuki's caretaker on Wet Crow's Feather Island, this friendly attendant plays a supportive role in her life, though Kanami can be quite willful. He deeply cares for her, even if he has a critical view of her personality. He sees himself and her as kindred spirits, both being companions to brilliant minds, though their connection is more of a friendly bond. Furthermore, he was instrumental in teaching Kanami the art of painting following her vision's recovery.
