Meltryllis (Swimsuit Lancer) in her First Ascension is a variant of the Alter Ego Servant from the Fate/Grand Order series, embodying a swimsuit theme with Lancer class traits. She exhibits a sadistic, queenly temperament that melts and absorbs others, transforming them into slimes via her Noble Phantasm. Her personality evolved from a pitiful girl to a belligerent one influenced by skills that steal opponents' abilities. At her core, she is the incarnation of 'self-pleasure' without need for others, yet driven by devotion to a loved one, raising her power through Drain to dominate and provide ultimate pleasure. Her 'star on stage' skill highlights independence and charisma honed in ballet and figure skating.
