Season 1 - Ten Count to the Future

Kirisawa had achieved a brilliant career in high school boxing, winning four championships, but he had suffered from injuries, the death of his wife, and other bad luck, so he could no longer imagine a bright future. Concerned about his situation, his best friend Kai and his former teacher Ashiya persuade Kirisawa to become a "temporary coach" for the boxing team at his alma mater. At first, he is reluctant to take on the job, but when he sees the high school students, covered in sweat and hitting the sandbag, "wanting to be strong" and "wanting to win," his own passion gradually comes back to him.
