In the hierarchy of the Otsutsuki Clan, the matchup between Kaguya and Isshiki is unique because it is the only "God-tier" fight with confirmed historical context.
According to Boruto: Naruto Next Generations, Kaguya was the lower-ranking partner who betrayed and nearly killed a high-ranking Isshiki. However, a full-power battle between them is far more complex than that sneak attack suggests.
The Historical Betrayal
Before the events of Naruto, Kaguya caught Isshiki off guard, severely wounding his lower body and forcing him to shrink and hide inside a monk named Jigen.
- The Context: This was a surprise attack. It does not necessarily mean Kaguya was stronger in a fair fight; it proves she has the "Attack Potency" to damage him if she lands a hit.
Combat Dynamics: Why Isshiki is the Favorite
Despite Kaguya’s betrayal, most power-scaling analysts place Isshiki above Kaguya in a direct, 1v1 confrontation for several reasons:
- Speed & Taijutsu: Isshiki’s physical stats are significantly higher. He effortlessly dismantled Adult Naruto and Sasuke, who were much stronger than the teenage versions that eventually sealed Kaguya. Kaguya’s combat style is often described as "clumsy" or reliant on raw power, whereas Isshiki is a master combatant.
- Sukunahikona vs. All-Killing Ash Bones: Kaguya’s most dangerous move, the All-Killing Ash Bones, turns anyone it touches to ash. However, Isshiki can shrink these bones instantly mid-flight, rendering her one-shot kill ability useless.
- Daikokuten vs. Dimensions: While Kaguya can shift dimensions (Amenominaka), Isshiki exists outside of normal flow via Daikokuten, a dimension where time does not flow. He can simply shrink himself to escape her dimensional traps or pull out massive black cubes that disrupt her ability to sense chakra.
Kaguya’s Win Conditions: The "Tank" Strategy
Kaguya’s greatest advantage is that she is functionally immortal and possesses significantly more chakra than Isshiki.
- Expansive Truth-Seeker Orb: If Kaguya can stall the fight long enough to create her Expansive Truth-Seeker Orb, she could potentially destroy the entire dimension they are fighting in.
- Energy Absorption: Kaguya can absorb chakra directly. If she manages to grab Isshiki, she could drain his already limited life force.

Conclusion
In a head-to-head battle, Isshiki wins the majority of the time due to his superior speed and his ability to shrink and nullify every single one of Kaguya’s ninjutsu-based attacks. Kaguya's only real hope is to outlast him, as Isshiki’s body typically has a very short "shelf life" when fighting at 100%.
