Two different characters that Araragi Koyomi encounters, Tsubasa is the main character of “Tsubasa Cat” while Mayoi is the main character of “Mayoi Snail”.
Tsubasa is Koyomi’s classmate and the class representative. She was possessed by a bakeneko during Golden Week due to stress over her family. Although it was resolved with Oshino Shinobu’s help at the cost of her own memories, problems emerged right before the school festival because of a different form of stress.
Mayoi, on the other hand, is the ghost of a fifth-grade elementary school girl who was killed in a traffic accident when she was trying to reach her mother’s house. She can only be seen by people who do not wish to reach their destination.
