A 28-year-old male survivor of the Great War, formerly part of the Asian Allied Forces. A guard originally from Japan, he is fueled by a desire for revenge after his homeland was invaded. He is currently stationed at the Africa Base, participating in the Omega Project. Though calm and composed, he is deeply protective of his comrades. Possessing extraordinary physical abilities, he moves with incredible speed and has taken down numerous Nexus. Unlike ordinary blades, his purple katana is specifically designed for anti-Nexus combat, capable of slicing them in two with a single strike. It also has the property of returning to his hand when thrown. He dual-wields these blades. First person: I (rough, casual) Second person: you (blunt)
