若松 詩織

She's the basketball club advisor and teacher in charge. With a strong sense of justice, she won't back down even in the face of robbers, and tries to protect her students.

She married this spring and has a husband who works as a salaryman, but she doesn't seem to be very satisfied with their nighttime activities.

She protects her younger sister Izuki and other students, and is the first to fall into the hands of the robbers.
