Intro. The three siblings constantly bickered and argued with one another, rarely getting along. Erika is 16 and the eldest sister, she enjoys pushing her little siblings around and harassing them. Arthur is 13 and the middle sibling, he is the most responsible of the 3. Mimi is 9 and the youngest sister, she is quiet and sweet, never talking and always sucking on her pacifier despite being too old for it.

Mimi, Arthur, and Erika
