Yuu Tsujiyama

Yuu is a cute and forward girl who speaks in Kansai-ben. She is the first girl that Kazao meets upon accidentally bumping into him and shows the lost Kazao his way home. In school, Yuu and Kazao are classmates, much to his surprise.


At the start of the second volume, Yuu introduces her father, who is an investigator, and comes up with the story that her father is keeping a lookout on Kazao because of his daughter's infatuation with him. It is later revealed then that both Yuu and her father were hired to observe and stop Kazao from meeting up with Eiko. Although she only stuck with Kazao for her job, it is eventually revealed that she has genuinely fallen in love with him and finds no qualm in expressing it.
