Smyera is the female high commander of King Gilmar's forces in Eristein. She presents an adult appearance characterized by dark skin, ear-length red hair, and distinctive purple eyes. Her initial encounter with Taichi Nishimura is hostile, as she deliberately challenges him to a practice fight to provoke him into revealing his true magical strength.

Immediately following their combat, Smyera's demeanor shifts dramatically. She expresses overt and direct romantic interest in Taichi, proposing marriage on the spot. She further declares her desire to have children with him and states her willingness to become his mistress if he is already involved with someone else. Taichi consistently reacts to these advances with visible discomfort and unease, maintaining a strictly platonic view of their connection.

Despite Taichi's clear rejection, Smyera actively continues her romantic pursuit in subsequent interactions. She employs seductive behavior, but these persistent attempts consistently result in Taichi's bafflement and rejection. Their dynamic remains defined by her unreciprocated romantic advances contrasted with his respectful but distant friendship.

No further details exist regarding Smyera's background, origin, childhood, family, character development beyond these events, involvement in later story arcs, spin-off media, alternate portrayals, or any significant evolution in her role or personality.
