Chapter 100: New Understanding of Mugetsu
A few days after joining the South Border Forest training squad, Rin began to see things differently.
For one, Mugetsu's strength.
In her mind, Mugetsu had always been an excellent teacher—his instruction level far above average—but she assumed his combat ability was similar to other Chunin instructors.
She now realized she had been wrong.
When Mugetsu taught Shisui Fire Release, the sheer force of the flames stunned her. It was the kind of power she had never imagined him using.
In the Academy, the Ninjutsu class only taught the Three Body Technique, but students often asked questions, and sometimes Chunin instructors would demonstrate other techniques.
Rin had never seen a Jonin perform Ninjutsu or fight, but she felt that even if Mugetsu wasn't quite on their level, he was still incredibly strong for a Chunin.
And it wasn't just Ninjutsu—Mugetsu seemed to be skilled in Taijutsu, Genjutsu, and even Medical Ninjutsu.
She also noticed that here, away from the Training Ground, he seemed more relaxed.
Then there was Obito's sudden diligence last semester. When she saw him slumped on the ground after losing a race to Guy—only to be handed a pile of assignments—she finally understood why she'd always seen him doing written problems.
Before, it had puzzled her. If Obito truly loved studying, why did he look so miserable doing it? And if he hated it, why did he work on it every single day? The contradiction now made sense.
All in all, Rin was glad she had become Mugetsu's disciple.

"Damn it! Just a little more!" Obito pounded the ground in frustration.
He had been so close to beating Guy to the finish line.
"It's okay," Rin said softly. "You were close this time. If you keep at it, you might win next time."
Her words instantly revived him. He jumped up, brushed off the dust, and shouted with renewed fire, "Guy, you just wait! I'll beat you tomorrow!"
"Obito, here are your thirty-five problems," Mugetsu said with a smile, handing him a test sheet.
The moment Obito saw it, all the energy Rin had restored drained away. He took the paper as if it were a poisoned cup, hands trembling.
"Didn't you say you love studying?" Rin asked, amused by his tragic expression.
"Yes… I love it too much," Obito said solemnly. "If I don't do at least a dozen problems a day, I feel… uncomfortable."
"Shall I add more, then?" Mugetsu asked lightly.
"Let's not. While studying is good, one shouldn't be greedy," Obito replied quickly.
"Continue training," Mugetsu said, tapping him lightly on the head.
In addition to teaching Rin Medical Ninjutsu theory, Mugetsu also gave her Taijutsu lessons. Medical techniques could be deadly in combat, and when paired with strong Taijutsu—like Tsunade's—the result was formidable.

Because it was Saturday, Mugetsu went to the Sarutobi compound that afternoon to train Asuma.
When he arrived, he found the Third Hokage seated in the living room, reviewing something.
"Third Hokage-sama," Mugetsu greeted.
The Hokage nodded, setting down the papers. "Mugetsu, how is your summer special training going? Three weeks have passed—most of the time is over already."
The Academy's summer break ran from mid-July to early September—about a month and a half. Special training was only scheduled for five weeks to leave some holiday time for the students.
"The students are diligent and eager to learn. Most have improved," Mugetsu replied after a moment's thought.
"I arrange tests each week to track their progress. I can go get the records now."
"No need. Just bring them tomorrow," the Hokage said with a chuckle. "But from what you've said, the results must be impressive. Perhaps Konoha will have another Special Jonin soon."
He planned to personally check their progress in the fifth week. If the results were as good as he hoped, he would make the training permanent. And if war truly pressed on Konoha, he might even suspend the fourth-year curriculum and have Mugetsu train them until graduation.
"Old man, I think you're getting senile. Mugetsu-sensei is so good—why not just make him a Jonin?" Asuma said bluntly as he walked past. "I don't think my Jonin instructor is even as good as him."
"Jonin are a key force for the village," the Hokage replied calmly. "They must excel in all areas, not just one."
Mugetsu's current mission count and quality were far from Jonin standards. His Special Jonin rank had been granted because of his outstanding teaching ability and decent combat strength—potential worth investing in.
"I think he's good in all areas. Why don't you make him principal of the Academy instead? You don't even go there much," Asuma muttered.
At that, the Hokage's blood pressure visibly spiked. He rubbed his forehead and waved Mugetsu away.
Understanding, Mugetsu nodded and led Asuma off to train.
"When will this child mature…" the Hokage sighed to himself.
The Academy had only ever had two principals: Tobirama and himself. Its founding was a milestone for Konoha, and even though the position no longer carried the same authority, it still held special meaning.
Unless a teacher made extraordinary contributions, the principal's seat would remain tied to the next Hokage.
He believed Asuma would understand someday.
