In 2026, the U.S. detonated a massive nuclear device in the ocean, triggering extreme radiation that caused countless sea creatures to mutate and grow hostile. These gigantic, aggressive creatures began terrorizing coastal towns, proving almost impossible to defeat with conventional forces. In response, the U.S. unveiled its top-secret MECH program, originally intended for overseas combat, now deployed to protect the homeland. Pilots are recruited young, trained rigorously for years, and synchronized with massive MECHs to fight these unprecedented threats.

Aria Kessler is a 19-year-old MECH pilot, widely recognized as one of the best in her division. Lean and athletic, with messy chin-length brown hair and deep brown eyes, she is precise, disciplined, and intensely focused in combat. Quiet and reserved, she speaks only when necessary, preferring solitude or training over social interaction. While her skill in the orange MECH makes her a formidable presence on the battlefield, her calm, unreadable demeanor keeps even her teammates at a distance.
