Description
M-21, a genetically modified human engineered by the Union under Dr. Crombel, was deemed a failed experiment due to volatile results. One of 100 subjects in the M-Series program, he endured early-stage trials merging werewolf and noble traits, surviving the lethal process through bureaucratic chance. Stripped of pre-experiment memories and original identity, he operated as a low-ranking Union agent alongside M-24 until defection.

His silver-grey hair obscures one eye, a jagged scar tracing his mouth, his lean frame concealing hybrid ferocity. When transformed, fur sheathes his arms and shoulders, claws extend, and his hair lengthens—a partial werewolf state fueled by an unidentified donor’s heart. Initially limited, this implant’s regenerative and physical enhancements fully activated only after intervention by Cadis Etrama Di Raizel.

Cold and rebellious early on, M-21 sought thrills in combat until alliances with Raizel and Frankenstein reshaped his purpose. M-24’s sacrifice to shield humans spurred his desertion from the Union. Joining Raizel’s faction as a Ye Ran High School security officer, he integrated into the RK-5 unit with Tao and Takeo, his loyalty and protectiveness eclipsing prior ruthlessness.

Strategic ingenuity emerged in clashes against Union operatives Jake and Mari, where he allied with former adversaries to defend innocents. Raizel’s awakening of his latent power during a Union data raid unleashed a full transformation, crushing an enhanced infected foe. Later battles against Ignes Kravei and Gaitan tested his resilience, relying on allies to counter superior enemies while honing his hybrid abilities.

Driven to uncover his lost identity and those of fallen M-Series peers, he abandoned this pursuit after learning the Union destroyed relevant data, redirecting his resolve toward thwarting the organization’s schemes. His antagonistic dynamic with Frankenstein softened into mutual respect, culminating in the latter revealing the werewolf heart’s origin during a medical assessment.

Captivity under Ignes Kravei and bonds with werewolves like Kentas complicated his self-concept, intertwining human, experiment, and beast. Despite unresolved identity struggles, his choices increasingly prioritize shielding allies, marking his evolution from a disillusioned weapon to a steadfast guardian.
