Haruna drums for High×Joker, the five-member light music band, and he's basically the sweet guy of the group—both personality-wise and literally, since he's obsessed with sweets and donuts. He's 18, which makes him notably older than the rest of the band (who are 16 and 17), because he got held back twice in school. That age gap is actually why he ended up joining the group in the first place. Beyond the music, he was drawn to the band partly because the others help keep him on track academically, and the whole thing ties into his bigger goal of becoming an idol.
