Moonlight Shigure came to the world of Naruto. For the first twelve years, he seemed very mediocre.
Average talent, average physique, average everything else except being handsome.
I thought I would live a mediocre life in the world of Naruto, but the sudden appearance of the skill bar made Shigure a genius. Any ninjutsu can be put into the skill bar, without control or operation, and it will run automatically.
Naruto: “Why are you so good at using the ninjutsu you just learned yesterday? Is there any secret to it?”
Sasuke: “You are the real genius, you have been playing me before!”
Kakashi: “Geniuses come out every year, but this year is particularly strong. As a teacher, I am under a lot of pressure. I want to retire, third generation!”
Third generation: “You want to retire? I still want to retire! That kid is simply not a human being. I am a remnant of the old era. There is no village that can let me stay in the new era!”
