Aya Iseshima

Aya is the main protagonist of the series. She is a high school junior and excels greatly in martial arts though she tries to keep the fact that she039s a good fighter a secret. It is hinted that she has a crush on her best friend Natsume039s older brother Haruki. She enters the contest for the Platonic Heart because her newfound friend Miko goes missing. Aya hopes that by winning the contest Miko will be found. It is shown later in Aya039s fights that she is somewhat of a coldhearted killer and a berserker who stops at nothing to defeat her opponent.
