Asahi Rokka is a first year high-school student at Haneoka Girls' High School. She goes by the moniker LOCK as the guitarist for the band RAISE A SUILEN.

She is in the same class as Asuka and Ako, and studies at Haneoka instead of Hanasakigawa due to a scholarship program.

Rokka is a slender girl of average height. She has sharp leafy green eyes and blue hair with her fringe splitting into three sections and her bangs reach her chins. The rest of her hair is resting on a shoulder-laying with a thick scrunchy with star ornaments.

She wears black glasses and wears a frilly dress with a bow behind with green socks and two strap flat brown shoes. Her necklace carries a key to her house.

When she performs, she takes both her glasses and scrunchy off.
