Tsunade folded her arms, noticing the scroll on the table.

"Is this the original concept for that Lightning Release Ninjutsu of yours?"
"That's right."
His initial promise to teach Nawaki this jutsu had been something of an empty promise.
But he had a conscience. He had to keep his word, not just talk without following through.
Using the talent for the Five Basic Nature Transformations he had gained from [Hiruzen Sarutobi's Training Notes] to reverse-engineer this ninjutsu, he had made fairly steady progress so far.
"Teacher, I'm going to begin," he said.
Tsunade put down the scroll, her expression turning serious. "All right. Focus on your training. With me here, no one will disturb you."
He nodded, then sat cross-legged on the floor, closed his eyes, and calmed his mind.
After obtaining the Spirit Transformation Technique from the Scroll of Seals, he had developed a certain understanding of it.
Put simply, mastering this jutsu required overcoming three hurdles.
He had to sense his own soul, or rather, his spiritual energy, separate it from his physical body, and finally give it tangible form.
The first step alone was extremely difficult.
An ordinary person's soul was tightly bound to their body. Even the idea of sensing one's own soul sounded rather implausible.
That was also why Dan Katō was the only person to have successfully mastered such a powerful jutsu.
There had never been a second.
It was somewhat like the Flying Thunder God Technique, placing extremely high demands on the learner.
Only one required an aptitude for space, while the other required an aptitude involving the soul.
But as it happened...
With a thought, he activated the [Spirit Sensing] trait.
