Combatants Engaging Upper Moon 4
Muichiro Tokito as Primary Assassin
Muichiro Tokito acts as the principal force against Upper Moon 4, leveraging his evolved Mist Breathing to dissect Kokushibo’s defenses. His near-perfect replication of Yoriichi’s techniques pressures the demon at every angle, making him the main answer to who fights upper moon 4 in infinity castle.

Tactical Breakdown in Infinity Castle
Environmental Exploitation
Infinity Castle’s shifting architecture forces Kokushibo to fight in confined spaces, nullifying some of his rotational slashes. Muichiro uses the confined corridors to maintain mist coverage, hiding movement and setting precise strike opportunities.
Coordinated Pressure with Allies
Sanemi and Gyomei tie down nearby threats, preventing Muzan’s fragments or other demons from interfering. This coordinated pressure ensures Muichiro can focus solely on Upper Moon 4 without being flanked or overwhelmed.
Power Scaling and Key Moments
Mist Breathing Mastery
Muichiro’s mastery of Mist Breathing allows him to predict and mirror Yoriichi’s forms, creating a fluid tempo that Kokushibo cannot easily counter. Each wave of mist erodes the demon’s stamina, pushing the fight toward a decisive moment.
Critical Turning Point
The turning point arrives when Genya’s desperate intervention forces Kokushibo into an overextended stance. Muichitro seizes this opening, landing the final blows that topple Upper Moon 4 and symbolize the collapse of Muzan’s elite guard.
Strategic Takeaways for Future Encounters
- Use environment constraints to neutralize large-scale rotational attacks.
- Combine precise breathing techniques with disruptive, high-risk allies.
- Coordinate focus fire to prevent demon regeneration from prolonging fights.
- Target stamina and rhythm early to force critical opening moments.
