Rikako Muto

Rikako Muto is a teenage girl who has just moved with her mother from Tokyo to Kochi. She is introduced to her school through the class president, Yutaka Matsuno, who hence introduces her to his best friend, Taku Morisaki. Yutaka (who instantly fell for Rikako) talks to Rikako about all things of life, including his best friend.
