Jawbreaker is a member of Sunnyside's band, Sunnyside & The Schisms. It plays the drums, and draws most of the promotional posters. Jawbreaker is their chosen name. It has a younger sister named Cady, an older sister named Mallory, and a pet cat named Poi. It is the youngest member of Sunny's band, and only joined due to Ana (bassist) and Mallory being school acquaintances. Jawbreaker makes their own patches and spikes their own clothes, their main interests being art-related. It is unpopular amongst peers, as such usually spending time with the band rather than kids their own age.
