President of koto music club. He's shy and weak in difficult situations. After his failure at the exam, depressed, Takezou saw his senpai's performance, where she was giving her all even though no one listened and koto's string had been broken. He was deeply moved by her performance, so he joined the club. After senpai's graduation, he became an only member of koto music club and had to find strength to protect it.
