Rin Sawaki

Rin Sawaki (often called "Class Rep" or Iinchō) is a supporting/main character in Dandadan. She's a high school student at Kami High School and serves as the class representative for Class C (the same class as Okarun/Ken Takakura).

She's depicted as a kind, caring, dutiful, and responsible girl who genuinely looks out for her classmates. She wears glasses, has long reddish-brown hair usually tied into low pigtails, and is known for being a talented pianist. As the story progresses, she becomes more involved in the supernatural events, gains spiritual abilities (including gravity manipulation through a guardian spirit connection after resolving a personal yokai-related issue), and plays a helpful role in several arcs alongside the main group.

Overall, she starts as the archetypal strict-yet-well-meaning class rep but grows into a more active and supportive ally in the chaotic world of ghosts, aliens, and yokai.
