Ruu Oka
Ruu Oka leads the Occult Research Club, though she's its only active member at this point. She's best known for connecting with the Pastimers Club and introducing them to occult-themed games and activities. Her role as the club's leader means she handles everything herself, but she doesn't seem to mind—if anything, she's enthusiastic about sharing her interests with anyone willing to listen.
