Misuzu Kamio

Misuzu Kamio is a slightly strange girl that is first introduced when she meets Yukito Kunisaki. With an obsession with dinosaurs (which goes back to her childhood), she finds it difficult to make friends and is constantly left alone. Because of Misuzu’s fondness of dinosaurs, she uses the word ‘Gao’ frequently, which is the noise she thought dinosaurs made when she was young.
