Asterio (アステリオ, Asuterio) is a female Minotaur, and the legendary master blacksmith of the town of Labyrinth who forges a new gauntlet for Eita. She is also one of the Autana that joined Eita Touga as a third traveling companion. When she fuses with his Gauntlet, she grants him the ability of metal remolding.
Asterio is very tall, at least half a times taller than any of the other non-Minotaurus characters. She is darker skinned and has long white hair.
Despite having a curvaceous body and large breasts, Asterio also has a defined musculature, specifically her visible and defined six pack.
Asterio primarily wears a cow print bikini along with bulky armor that covers her arms, shoulders, and legs and a helmet shaped like a bull's head with a nose ring.
Like many of her kind, Asterio is relaxed most of the time, even in dangerous situations. She is happy-go-lucky and somewhat absent-minded, Asterio doesn't seem to notice or care about Eita's accidental perversions, and almost always has a smile on her face.
She is, however, very dedicated to her craft as a blacksmith, almost to the point of having a fetish for metal. If there is work to be done, then that will take precedence over anything else, even if the town is being attacked by Gigas, and was perfectly willing to let Eita touch her breasts in order for him to generate enough power to defeat them.
She has the most plot. Obviously.
Asterio has the incredible strength credited to all her kind. When she fuses with his Gauntlet, she grants him the ability of metal remolding.
She is also a skilled blacksmith of legendary renown, and one of the few who can shape Masquerade Metal.
