Gyutaro is powerful enough to be upper moon 4

I have to assume you're arguing Gyutaro deserves Upper Moon 4 status based on raw power alone. That's where your logic collapses. The Twelve Kizuki ranking isn't meritocratic strength olympics, it's historical longevity and demonstrated dominance over centuries. Gyutaro was literally created two years ago. He'd need to solo multiple Hashira simultaneously and sustain that performance for decades to justify displacing an established Upper Moon. You're confusing a single impressive feat with the systematic track record required for elite ranking. What evidence shows he's outperformed Upper Moon 4's actual centuries of conquest?
