Siren Sensei Ref WIP (Patreon)

The nurse and art club advisor, she's technically both a main and side route since she will obviously be around in the art club but her route is very different from the main 3 girls 

Unlike the other three girls I've already thought of her name by now cus I've gotten much further with writing the scenarios, she's Io Calla, just called Ms. Calla by the students
