Arisu teaches at Hosea Academy, where she runs the Phantom Hunter Club and handles job assignments for students with powers. Basically, her role is to match teams with phantom-related work that needs doing—the students take on the jobs, deal with whatever supernatural trouble shows up, and get paid for it. She's also responsible for organizing and assigning these teams to different cases.
What makes her stand out is how genuinely kind and composed she is. Students feel comfortable coming to her with their problems, and she actually takes the time to help them work through things. That's why she's so popular; she's the kind of teacher who actually cares, not just someone handing out assignments from behind a desk.
