#05-Yoru Caged Budding Sun Yoru is the rhythm guitarist for The Heart Throbs and younger brother of band member Kazuo. He is the youngest member at 17, and was lead guitar before Doki and Azuki joined. His heart dropped and he felt great discomfort at the thought of being replaced and even thought of quitting outright, that was at least until he set his eyes upon Doki for the first time.
