Okusawa Misaki is a second-year student at Hanasakigawa Girls' High School and a member of Hello, Happy World!. Under the "guise" of the mascot character Michelle, she is the DJ and composer of the band; as Misaki, she is the composer and Michelle's "agent". 

Misaki is kind, reserved and considerate, however she is also known to reply sarcastically and sometimes struggle with the other girls in her band, with the exception of Kanon, whom she considers the only other reasonable member. Naturally, she ends up becoming the "straight man" of the group, scolding or commenting on the antics of the other members in immediate response.

Despite her hardworking nature, especially towards Hello, Happy World!, she tends to debase her achievements and say how anyone else could've done it instead of her. For example, whenever people praise her for being able to understand Kokoro's hums and make them into songs, she'll shrug it off with a "it's nothing special".
