Yoko

Yoko (ヨウコ, Yōko) is a minor antagonist in the Fairy Tail series, specifically appearing in the 100 Years Quest sequel (adapted into the anime Fairy Tail: 100 Years Quest).

She is a member of the Moonlight Divinities (also called Moonlit Divinities), an all-female group of elite underlings serving the Moon Dragon God Selene. Yoko is known as "Yoko of the Demons' Parade" (百鬼夜行のヨウコ) due to her Spirit Arts ability to summon and control an army of yōkai (demonic spirits/ghosts from Japanese folklore), including various types like bakeneko, kasha, and others. She can also transform herself or others into yōkai forms and uses this power aggressively in battle.

She has green hair, black eyes, and wears an old-fashioned Japanese-style yukata, giving her a traditional yokai-themed aesthetic. Yoko acts as one of the secondary antagonists during the Moon Dragon God arc in Elentear, often teaming up with fellow Divinities Hakune and Mimi to confront members of Fairy Tail (particularly Erza, Wendy, and Carla).
