A haughty, stubborn girl who goes to an exclusive all-girls' school called Banda Academy. Flower-shaped Amapora is her dragonet companion, and she befriends Shiina, who does not know of her evil intentions. She wishes to kill people, but lacks the strength until she finally unleashes her power on civilians, creating a city of corpses. She fulfills a favor for Sudo by kidnapping Akira, who is believed to have a dragon. She used to have a romantic relationship with Bungo, but for some reason her priorities moved to the dragons. Satomi holds a particularly strong grudge against Shiina for both killing Komori and attempting to stop her malicious plans, and often discusses with Bungo her desire to kill Shiina.
