"Well..." Naruto looked troubled. "It's not that I don't want to. It's just that Kurama, Dad, and Pervy Sage all agreed to classify my Metamorphosis Mode as a Forbidden Technique. They won't let me use it normally."
"A Forbidden Technique?"
"Yeah. They said Metamorphosis Mode burns chakra and might directly affect my lifespan, so I'm not allowed to use it unless there's no other choice. I haven't felt anything like that myself, though.
"They even made a point of telling me the village had officially classified it as a Forbidden Technique. I can't exactly break the rules."
Naruto scratched his head and chuckled.
"I see."
Hearing that Metamorphosis Mode could affect Naruto's lifespan, both Sasukes immediately abandoned the idea.
But seeing the two of them give up so readily actually made Naruto feel a little embarrassed.
Kurama~
"What?"
The moment the Nine-Tails heard that rare, wheedling tone from Naruto, he knew what Naruto was planning.
Just a quick look should be fine, right? When that Ōtsutsuki guy came over before, you didn't stop me from using this power, did you?
"Even if I refuse... Oh, right. You do need my permission."
The Nine-Tails recalled what had happened a few days earlier—
Metamorphosis Mode had actually been classified as a Forbidden Technique mainly at Minato and Kushina's insistence.
After hearing the Nine-Tails say that Naruto might die from burning his chakra, Kushina had told Minato about it.
Because of that, both Minato and Kushina had warned Naruto over and over, and had earnestly asked the Nine-Tails not to let him do anything reckless.
The Nine-Tails cared about Naruto too, but he had to admit that he also wanted to study this power.
No matter how he looked at it, this power shared similarities with the Baryon Mode he had once developed,
