An "Acolyte" of Watanabe Akino, Chelsea is a student with "Eighth Grade Syndrome", with her delusion being that she is also half demon like Arene, using her heterochroma as evidence (Her odd puples are from using contacts to emulate her "True Form"). also suprisingly good at Hanafuda. Fun fact: the face marking and her "Magic conductors" are temporary tattoos she made herself.
