Sin

A dark mirror of Sailor Moon, Sin keeps Usagi's blonde shade but drops the odango buns, wearing her hair instead in two long, zigzag-tipped ponytails bound with red ribbons; her fringe leans closer to Queen Nehelenia's than to Usagi's. Purple tones tint both her eyes and her gear. She wears a full black bodysuit patterned in purple and white, a broad white collar studded with gold plates in the manner of Galaxia's, and an upside-down heart with a red tie that flips Sailor Moon's usual brooch and bow. Gold anklets, bracelets, and triangular earrings round out the look, along with a tiara marked by a triangle.

Grief has curdled into madness. She holds Neo-Queen Serenity responsible for failing to save her parents when the Black Moon Clan struck, and that fury defines her. Her younger brother Anshar is the only family she has left. She serves the Deity of Destruction, Shaman Apsu, as one of the Oppositio Guardians.

Sin fights with a broad arsenal of destructive techniques. Her signature Hell's Attack fires a wide energy beam at the entire Sailor team, while Hell's Surge lands a single devastating blast on all of them at once. Genkaku confuses a target for five turns, turning it against friend and foe alike while locking out items and skills. Kamaitachi rains rapid slicing hits across every opponent, Toxic Mist deals damage with a chance of poison, and Sonic Wave petrifies a Guardian until a healing item frees her. Notably, she is the only Oppositio Guardian who lacks the Miryou attack.
