Sasami Sasasegawa (笹瀬川 佐々美)

Sasami is a girl at Riki's school and is Rin's rival. While Rin loves cats, Sasami is a devoted dog lover. Due to this, she will often get in a fight with Rin, though since she is the captain of the girl's softball team, she will send in her members first before she goes in herself. Her name is thought to be a tongue twister, which even she manages to mix up, and she likes Kengo Miyazawa.
