Kyoka Shinohara, a teenage girl from Aoba-ku, Yokohama, bears long purple hair swept into low twintails and piercing yellow eyes. Once part of a commando unit decimated by the metallic Mimesis, she emerged as the lone survivor, her resolve hardened into a singular pursuit of vengeance. Now commanding a new LBX Girls squadron, she pilots the close-combat-focused Deqoo-type LBX armor, channeling her tactical acumen and haunted past into leading the fight against the alien threat.

Driven by loss and survival, she transitioned from her shattered unit to unite displaced girls in an alternate Japan, forging alliances to eradicate the Mimesis and reclaim peace for both worlds. While her leadership steers the team through battles, her guarded demeanor masks a personal quest for retribution, balancing camaraderie with an unyielding focus on her mission. Her attire—a practical sweater and skirt—mirrors her no-nonsense approach, with no recorded details on family ties or life beyond her role as a soldier shaped by tragedy.
