|Age||Presumably in her late 20's|
Matsuda is Hiou Uesugi manager.
Her first name is not known yet. She seems to be a quite reasonable but soft person. She tells Kyoko what really happened when Hiou was wounded by Kanae, and tells the truth about the seriousness of his wound. However she seems to visibly flinch when Hiou scolds her for doing this, implying she's probably not a very strict or hard individual. She seems willing to follow Hiou and not put many limitations on him. She goes with him when he spontaneously follows Kanae to her home without any objections.
