Natsuki fell into thought.
Of the four abilities that needed to be unlocked for the Aizen template, the Hōgyoku could be saved for last.
Its unlocking condition was the most difficult.
Absorbing the power of all nine Tailed Beasts was no easier than directly unifying the Ninja World.
He could not accomplish that for the time being.
Nor was it something that could be done in a short period.
He could start preparing to unlock the remaining three abilities.
Among Kumogakure, Iwagakure, and Kirigakure, the three major ninja villages, Kirigakure was undoubtedly the easiest to control.
Its overall strength was the weakest.
Furthermore, the Third Mizukage was also currently the weakest among the Five Kage.
Coupled with his unlock condition of killing a Kage Level expert, the Third Mizukage was a good choice.
In the original story, Uchiha Obito had chosen to control Kirigakure after going dark.
Though Nohara Rin's death at Kirigakure's hands had been a factor, the fundamental reason was still that Kirigakure was the weakest.
If Uchiha Obito had chosen to control Konoha, there would have been two problems.
First, he might not have been able to defeat Hiruzen Sarutobi.
Second, Konoha had the Hyuga Clan. The Byakugan could tell whether a target was under Genjutsu control.
Controlling Kirigakure would be somewhat more difficult for Natsuki than it had been for Uchiha Obito.
Because he also had to establish the Espada.
The Espada required ten Kirigakure jonin.
Natsuki thought of Pakura.
The best way to control Kirigakure was still to support a new Mizukage.
That way, he could also fulfill the condition of taking an enemy ninja as his student.
Terumi Mei appeared in Natsuki's mind.
Terumi Mei was the same age as Hatake Kakashi, around ten years old now.
She was a suitable age.
Natsuki nodded.
