Kakashi's Chidori is an A-rank technique.
After obtaining the Sharingan and entering the ANBU for training,
Kakashi supposedly continued cultivating his Chidori until one day, he used it to sever a bolt of lightning.
Thus,
he upgraded the A-rank Chidori to S-rank in one stroke.
It became the S-Rank Technique: Lightning Cutter.
The Storm Release Hyuga Sho had just used was basically equal in power to the Lightning Cutter.
But its advantage was...
Storm Release fired out as a beam of light, and when it exploded, it dealt AOE damage over a wide area.
In that regard, it had a certain advantage over the Lightning Cutter.
Its weakness was its chakra consumption, which was far greater than the Lightning Cutter's.
The young Kakashi of the present could use the Lightning Cutter two or three times a day.
As for his own Storm Release... he could only use it once a day.
"So this is a trump card for a killing blow."
The fewer people who knew a ninja's trump card, the more powerful it was.
As the number of times it was used increased, information about it would gradually leak out and become known to more people, causing its danger to decrease to a certain extent.
After breaking free of the Caged Bird Seal,
Hyuga Sho's mentality had become steadier, and he was also... revealing more of his true nature.
His former foolhardy disguise was gradually fading away.
One day, he would tear away all his disguises in front of everyone.
Now that he had reached Kage Level, with life and death settled,
Hyuga Sho was ready to start planning what came next.
Overturning the Hyuga clan, killing Shimura Danzō, becoming Hokage, wiping out the Akatsuki Organization... these were major events.
Recruiting Shinno and Sasori, arranging the Legal Maiden Plan
