Shin Megami Tensei III: Nocturne
Kin-ki is one of four optional bosses that can be fought in the Ikebukuro Tunnels. During the fight, he will regularly cast Beast's Eye, followed by a buff or debuff, and ending with a physical attack, such as Blight or Hell Thrust. Once his health reaches a low enough point, he will switch to Dragon's Eye. For this battle, it is recommended to bring demons with Dekaja and Dekunda to counteract his strategy.

Shin Megami Tensei IMAGINE
Kin-Ki can only be obtained through fusion. He appears as a field boss on Shinjuku field when summoned by one of the charms the Yaksini NPC in Ichigaya Camp's B11 will trade for magnetite. A strengthened variant called Peerless Steel-Bodied Kin-Ki can be fused by players after completing a series of G1 Trial quests from a Cathedral of Shadows researcher in Ikebukuro. This variant learns the unique skill Lightning Flash Massacre.

Shin Megami Tensei IV
Kin-Ki is the sub-boss faced at the end of the Challenge Quest, I Want to Make the City Bright. He has created a Domain over a relic spot in Ueno - Central Way and must be defeated to obtain the LED Lightbulb. He can be refought for the item he has after a certain amount of time has passed.

Kin-ki later appears as a normal enemy in Infernal Tokyo.

When itemized through Electric Chair execution in the Velvet Room, Kin-Ki yields a Regenerate 1 Skill Card.

Kin-Ki's Dodge Psy skill can be used in a fusion recipe to further the Strength Confidant with Caroline and Justine. After leveling Kin-Ki to level 27 so he learns Dodge Psy, the protagonist can fuse him with Sui-Ki to produce the desired Ame-no-Uzume that knows the Dodge Psy skill.

Trivia

 * Kazuma Kaneko did not intend Kin-ki to use any weapon, unlike his fellows. But likely for saving an individual set of skeletal animations, his 3D model is given the same club of Oni and uses the same attack animation. This design decision continues to Persona 5, when all 3D models and animations were given a revamp. In Persona 5 Royal his club is removed and given a new set of animations.
