Artemis  

Art

Hazuki's younger sister has been receiving more attention from their family due to the popularity of her older sister, Art. This has caused envy in Art, who feels that she deserves the same level of attention. As a result, Art has become determined to take away everything and everyone that Hazuki cares about, either by force or destruction. In the final episode, after Balgus' death, Hazuki is welcomed into the Morioka family. Kouhei helps her see the potential for a new life with caring friends and family, leading her to open up and embrace this change. It is revealed that she is a Shadow User.
