Sumire Kano

Third-year student. She is the female student council president who consistently maintains top grades. A scholarship student. She holds ranks in kendo and aikido, and her eyesight is so good that it cannot be measured. Despite her Yamato Nadeshiko-like appearance, her overly masculine and bossy demeanor leads students to call her "Aniki" or "the brother of the Kano sisters." She is afraid of snakes and is very weak to alcohol. Her family runs a local supermarket called "Kano-ya."

During her exam period, "Kano-ya" faced financial difficulties, which led her to enroll in her current high school that offered a scholarship with tuition exemption. Her dream is to go to space. She places complete trust in Yusaku and often acts together with him. Upon completing her term as student council president, she studied abroad in America as a step towards becoming an astronaut. She and Kitamura had mutual feelings for each other. However, she was convinced that "Kitamura would follow me even at the cost of his own life," and to avoid ruining his life, she deflected his confession and left for America.
