A protagonist in Love Live! Sunshine!!. Hanamaru is a diligent girl who was raised in a temple and loves books. Because of her upbringing, she is easily fascinated by technology. She tends to end her sentences with the verbal tic "zura", due to her Shizuoka dialect.
She is a member of the Aqours sub-unit AZALEA, alongside Kurosawa Dia and Matsuura Kanan. She looks up to Hoshizora Rin from predecessor µ's. Like Rin, Sega also selected her as an image girl to feature in advertisements alongside Sonic.
