Background
Born with a Heavenly Restriction that gave him cursed energy range spanning all of Japan in exchange for a body that couldn't walk, sit up, or endure sunlight. Kokichi participated in jujutsu society through his puppet Mechamaru, fighting remotely while his real body lay hidden in darkness.

Episode 14
Kokichi Muta's technique let him fight from across the country. Born with a Heavenly Restriction that gave him extraordinary cursed energy range in exchange for a body that couldn't walk, sit up, or survive exposure to natural light, Kokichi controlled mechanical puppets remotely. His range extended across all of Japan. He could operate Mechamaru from hundreds of kilometers away. The technique turned engineering into combat. Kokichi built puppet bodies with modular capabilities, ranged attacks, shields, flight modes, blade configurations, each one a tool for a different problem. His cursed energy fueled the puppets, and the extensions he developed (Ultra Cannon, Ultra Shield, Mode: Albatross, Sword Option, Boost On) expanded Mechamaru's combat vocabulary. Ultimate Mechamaru was his masterwork: a puppet body loaded with seventeen years of stockpiled cursed energy, powerful enough to challenge a special grade.
Technique
Boost On
推力加算
A temporary power spike for Mechamaru's puppet body. Kokichi channels extra cursed energy into the mechanical frame, pushing its speed and striking power past normal limits for a short burst. The trade-off is rapid energy drain, useful for breaking a stalemate, dangerous if the fight drags on afterward.
Technique
Miracle Cannon
二重大祓砲
The peak offensive output of Mechamaru's standard arsenal. Kokichi channels cursed energy into a concentrated beam fired from the puppet body, hitting hard enough to threaten cursed spirits and damage structures. It's his 'big gun': the attack he saves for when normal combat isn't cutting it.
Technique
Mode: Albatross
砲呪強化形態
Mechamaru sprouts wings and takes flight. The puppet body transforms into an aerial combat configuration, trading ground-level fighting capability for three-dimensional mobility. It's a repositioning tool. Kokichi used it to escape unfavorable ground situations or attack from angles that grounded opponents couldn't easily defend.
Technique
Pigeon Viola
追尾弾~五重奏~
Rapid-fire cursed energy projectiles from Mechamaru's puppet body. The individual shots aren't powerful enough to be lethal against strong targets, but the barrage is sustained and suppressive. It pins opponents down, limits their movement options, and forces them to either tank hits or waste time dodging instead of attacking.
Technique
Sword Option
刀源解放
Mechamaru's arms become blades. A simple reconfiguration that gives Kokichi's puppet body melee capability when ranged attacks aren't viable. The blades are serviceable rather than exceptional, they cut well enough to threaten opponents but don't match dedicated melee weapons in reach or technique.
Technique
Ultra Cannon
大祓砲
Mechamaru's standard energy beam, less powerful than Miracle Cannon but efficient enough for repeated use. It's the everyday tool in the arsenal, the attack Kokichi used when situations needed consistent damage output rather than a single overwhelming shot.
Technique
Ultra Shield
剣山盾
A cursed energy barrier projected around Mechamaru's puppet body. The shield absorbs incoming attacks up to its energy threshold, providing a buffer that keeps the relatively fragile puppet frame intact through exchanges that would otherwise destroy it.
Technique
Ultra Spin
絶技抉剔
Mechamaru's entire body rotates at high speed, turning the puppet into a spinning projectile. The centrifugal force amplifies impact on contact, making it an unexpected melee attack from a primarily ranged fighter.
