Saya tends to be a very mean and somewhat impolite person. Being a genius, Saya always considers herself right and because of this can be considered 'stuck-up'. Despite being this way, Saya has been shown to be a very caring person and looks out for the rest of the group, mostly Takashi Komuro due to her crush on him. Saya also considers herself to be a mother figure or an older sister figure to Alice and will scold anyone who tries to ruin her innocence.
