Free is an Asiatic lion with light golden-yellow fur and a striking strawberry-blond pompadour mane, marked by a scar over his right eye. His tattoos—the characters "猫邪羅死" (Nekojarashi, "cat teaser") stretching from collarbone to stomach and lion paw prints on his shoulders—underscore his bold identity. As a Shishigumi member, he dons a brown suit and tie, though his anime portrayal softens his ferocity with visible pupils and a less rigid demeanor.

Raised in the Black Market, Free initially resisted Louis’s leadership, distrusting a herbivore’s ability to control the gang’s predatory urges. Louis’s competence gradually earned his loyalty, aligning Free with Ibuki and Dolph as key enforcers during operations, reflecting the Shishigumi’s strengthened reputation under Louis’s command.

During a wolf gang turf war, Free and Dolph depart to buy cigarettes, missing Louis’s abrupt decision to abandon the group. When Ibuki attempts to devour Louis in a frenzied bid to keep him, Free honors their pact to protect the leader, shooting Ibuki. He then escorts Louis to the Black Market’s border, cautioning that a future encounter would force Free to act on his primal instincts.

Eccentric yet principled, Free balances personal indulgences—female lions, violent thrills, billiards, and aggression-heightening silver vine—with unwavering adherence to the Shishigumi’s chain of command. His moral pragmatism tethers his wild nature to collective loyalty, enforcing agreements while navigating the gang’s volatile dynamics.
