Albertina II

Often referred to as "Bell" for short, she is a third-year student and secretary of the Shimoshina student council. Albertina II is a pen name she uses as a popular manga author. She works on multiple manga projects simultaneously and uses Hime as the basis for the main character in her manga, Magical Boy Hime Kiss.

She can be very terrifying when flustered and she also has a certain complexity toward her flat chest.
