Milo, identified as Miro, is one of a twin pair of magicians. Alongside her twin sister Melo, Milo initially served Cardinal Lodra. Their tasks included alchemizing Crimson Pact Goblins for the assault on Azpire. During this operation, the twins displayed a disturbing eagerness for violence, gleefully anticipating the goblins' attacks on the city's population.

Their circumstances shifted drastically when the destruction of their control crystal caused the goblins to turn against them. Facing imminent death, they were rescued by Taichi Nishimura. This rescue prompted their defection from Cardinal Lodra's group, leading them to join the Azpire Adventurers Guild instead.

Milo wields Earth Magic. Her primary and signature spell is "Falldown," which generates potholes to ensnare opponents. Melo possesses this identical magical ability.
