Description
Kyoichi Takame, alias Loki, served as the Fourth Fist in the delinquent organization Ragnarok, functioning as its key strategist and martial artist. He wielded a specialized karate style centered on "tame"—spear hand techniques that channeled strikes through every joint in his arms, from fingertips to shoulders, for rapid multi-hit assaults. His combat arsenal included pressure point attacks like eye gouges and proficiency with customized double-ended stun batons, though he seldom deployed weapons directly.

As Ragnarok's primary tactician, Loki exploited opponents' weaknesses through sharp intelligence and manipulation, deliberately inciting internal conflicts by weaponizing members' personal beliefs and rivalries. Notable schemes involved blackmailing Hermit using his debt to Ogata Isshinsai and kidnapping Kenichi Shirahama's younger sister to control both Hermit and Kenichi. He trained covert operatives called "Shadows" who impersonated him to disorient and ambush adversaries during missions or duels.

Loki secretly plotted to overthrow leader Odin, aiming to install Berserker as a puppet figurehead while retaining actual control. For this coup, he prepared a replacement unit dubbed the "New Eight Fists." Berserker effortlessly dismantled the plot by defeating Loki and his forces. Post-Ragnarok's dissolution, Loki established a detective agency, accepting intelligence contracts from Haruo Niijima of the Shinpaku Alliance. He supplied critical data on organizations Yomi and Yami, repeatedly infiltrating the impenetrable Yami through investigations blending legal methods and underworld contacts, maintaining his deceptive, coercive reputation.

Driven by pragmatic self-interest, Loki's post-antagonist actions retained moral ambiguity, aligning cooperation with Niijima to personal advantage. His combat capabilities rivaled elite martial artists, featuring Small Building-level attack potency, supersonic speed, and Class 100 lifting strength. Key vulnerabilities included standard human frailty and occasional underestimation of opponents' endurance, exemplified when his "tame" strikes faltered against Kenichi's resilience.
