Tsunade watched Watanabe sitting motionless before her with his eyes closed, guessing that he had begun practicing the Spirit Transformation Technique.
The Watanabe home was very small. The two of them were sitting cross-legged on the sofa, close enough to hear each other breathe.
"Although the Spirit Transformation Technique is relatively simple, it requires you to temper your willpower for a long time. It'll be quite impressive if you can master it within two years."
Tsunade thought to herself.
If Watanabe could master the Spirit Transformation Technique before graduation, he would have the makings of someone who could stand on his own.
Then Tsunade put the matter aside and began her own training.
She was extremely busy in her daily life. She had to learn the Hundred Healings Jutsu and the Yin Seal, as well as Medical Ninjutsu, Taijutsu, and more. Each one required a great deal of effort. If the other person weren't Watanabe, she wouldn't waste her precious time on him.
Time passed, second by second.
About half an hour later, Watanabe finally sensed his soul in the Spiritual World. The connection between them was very weak.
Following the method recorded on the scroll, Watanabe tried to separate his soul from the Spiritual World. The process went surprisingly smoothly. He only felt something warm flow out of his body, and then he saw it.
In the cramped living room, Tsunade sat quietly in front of him. Her delicate oval face was flawless, fair, and beautiful.
Behind Watanabe was another "Watanabe," sitting quietly like a statue with his hands forming the "Rabbit" seal.
Watanabe looked down and saw that he was now in a ghostly, semitransparent form.
"I did it? It was that simple?"
Watanabe was astonished. He hadn't expected to transform his soul and separate it from his body so easily.
"Looks like my soul really is strong enough..."
Just then, Watanabe suddenly felt a stabbing pain in his head. His soul was growing weaker by the moment.
"Every time the soul leaves the body, it suffers some degree of damage." Watanabe pondered this without panicking. He had read through the entire scroll and knew this was a normal side effect of using the Spirit Transformation Technique.
The longer the soul stayed outside the body, the greater the damage it would suffer.
Just as Watanabe was about to end his training, a row of text appeared before his eyes:
[Soul damaged: Soul Strength +1, +2, +1...]
Watanabe was delighted. He could clearly feel that his soul, which should have been growing weaker, was instead becoming stronger and stronger under the effects of Karma Reversal. The stabbing pain in his head had also turned into a pleasant sensation.
"The Spirit Transformation Technique combined with Karma Reversal is absolutely incredible!"
Watanabe slowly got used to his soul form, floated into the air, and flew low around the living room. It was something he couldn't do with his physical body.
"Would Tsunade be startled if she saw me like this?"
Watanabe suddenly wanted to find out what it felt like to possess someone, so he carefully descended toward Tsunade.
He believed that, given his relationship with Tsunade, she wouldn't mind him using her to test the effects of a jutsu. Tsunade was very generous toward her friends.
The moment they made contact, Watanabe felt as if he had touched a warm, elastic membrane.
Tsunade was refining Chakra when she suddenly sensed something amiss. Her brows furrowed. "Hm?"
Watanabe said, "Relax."
Then he squeezed inside.
"Mm~~"
"Wait... What's going on?!"
Tsunade's eyes flew open. The horrible feeling of someone forcibly invading her body terrified her.
"Don't be afraid. I'm trying out the Spirit Transformation Technique to possess someone."
Watanabe's voice rang out deep in her mind as he hurried to reassure her.
Tsunade was stunned, her mind buzzing.
"Watanabe, is that you?"
She looked at Watanabe sitting motionless in front of her.
"Yeah. The Spirit Transformation Technique really is amazing."
His voice sounded in her mind again.
Watanabe tried to connect with Tsunade's Spiritual World. Her vision blurred, and then she saw another Watanabe who had entered her body.
In his soul form, Watanabe grinned as he explained, "Tsunade, I just tried it. After entering your body, I can not only provide you with Chakra, like this..."
As he spoke, Tsunade felt a surge of pure Chakra appear inside her.
"I can absorb your Chakra, too, like this..."
As he spoke, a portion of Tsunade's Chakra was suddenly drained away.
"And I can control your body, like this..."
Tsunade remained completely dumbfounded the whole time. Her arm rose and fell against her will, then fell and rose again.
After moving her around a little, Watanabe felt the immense strength in Tsunade's body. It seemed like she could smash anything to pieces with a casual gesture. When she had sparred with him yesterday, she hadn't even used a tenth of that strength.
Watanabe couldn't help exclaiming, "Tsunade, your body is truly amazing!"
Tsunade: "..."
She finally came to her senses and said indignantly, "Have you had enough? Get out!"
A powerful pressure surged toward Watanabe, forcing him out and back into his own body.
Watanabe opened his eyes and saw Tsunade glaring at him angrily. He immediately felt a little guilty. "Tsunade, are you mad?"
Tsunade replied irritably, "What do you think?!"
Someone had taken over her body without warning and made some embarrassing comments about it. The only reason Tsunade didn't beat him to a pulp was that the person in question was Watanabe.
"Sorry. I only wanted to try out the Spirit Transformation Technique. I thought you wouldn't mind..."
Watanabe meekly admitted his mistake.
Seeing how quickly he apologized, Tsunade couldn't bring herself to lose her temper. Once she had calmed down a little and thought about it, she suddenly realized how incredible it was.
In that short time, Watanabe had managed to use the Spirit Transformation Technique to enter her body?
How had he done it??
Tsunade had practiced the Spirit Transformation Technique before. She didn't like the jutsu because it required a huge investment of time and effort at the beginning. Just tempering one's willpower took years of preparation, and progress was too slow. In the end, Tsunade had decisively given up on it.
But how long had Watanabe just spent?
Half an hour?
Tsunade had never imagined that Watanabe could have such astonishing talent for the Spirit Transformation Technique. The word "genius" wasn't enough to describe him!
"Use the Spirit Transformation Technique once more so I can see," Tsunade said.
"Okay."
Watanabe formed the Rabbit seal. He still wasn't very familiar with the jutsu.
Half a minute later, Watanabe's soul emerged from his forehead, swaying unsteadily in the breeze.
[Soul damaged: Soul Strength +2, +1, +1...]
A look of surprise flashed through Tsunade's beautiful eyes. Afraid of hurting Watanabe, she reached out and touched him gently.
Her hand passed straight through. There was nothing solid to touch.
"Why were you able to master the Spirit Transformation Technique so quickly?" Tsunade asked, unable to understand.
"Maybe my soul was naturally strong, so learning it went smoothly," Watanabe explained.
Tsunade nodded, accepting his explanation.
She couldn't think of any other reason.
"You can't use the Spirit Transformation Technique for too long. It can damage your soul. Hurry up and end it."
Tsunade had been the one who wanted to see the Spirit Transformation Technique, and now she was the one urging Watanabe to end it.
