Natsuki let out a breath.
The Hōgyoku's effect was to fulfill its user's wishes.
But the prerequisite was that the user had the potential to fulfill that wish.
Of course, it also required sufficient energy, or rather, chakra.

Of course, the main reason was that stacking several character templates had raised his potential to a frightening level.
"Natsuki."
Uchiha Mikoto's voice rang out.
"When did
