Clearly, Kakashi had beaten Guy thanks to his Shadow Clone Technique.
Kazuhiko had watched their youthful showdown from beginning to end, but he hadn't noticed when Kakashi used the Shadow Clone Technique.
Uchiha Fugaku had arrived even later, so there was no way he could have noticed either.
With the Gate of Healing open, Guy had kept Kakashi, who had opened the first Gate, completely suppressed. Under those circumstances, anyone watching would have predicted that Might Guy would win.
So why had Fugaku been so certain that Kakashi would win?
Kazuhiko cautiously asked, "It seems you saw how the match would end in advance, Clan Head Fugaku. Was it because you thought Kakashi was stronger?"
"Kakashi is no match for Might Guy," Fugaku replied, still certain.
"You were right just now. Although Kakashi used the Sharingan to master over a thousand jutsu, even if he gave it everything he had, he still wouldn't be Might Guy's match."
Something was off. You were seriously acting suspicious!
Kazuhiko looked at Fugaku, strongly suspecting that he had used his Mangekyo ability on Guy.
At this point in time,
Kakashi was ranked as an Elite Jonin.
Might Guy, on the other hand, was a Jonin.
There was a clear difference in their ninja ranks.
In other words, according to Konoha's ranking system, Kakashi was far stronger than Might Guy.
Kazuhiko knew Guy was stronger because he understood how powerful he really was with the Eight Inner Gates.
Guy might not yet be able to kick his way to an ending, but with the higher Gates open, he was definitely stronger than Kakashi. Kazuhiko was sure of that.
If Guy's favorability had given him something better than a [Jonin Trait Draw], Kazuhiko might even have thought Guy was Konoha's strongest ninja, capable of reaching beyond-Kage-level
