Kaida meditated and practiced until 10 PM, finally mastering his fifth and last jutsu. He went to Yukihiro and demonstrated the jutsu. Seeing Kaida's dedication, Yukihiro smiled and said, "Well done, Kaida. Learning five jutsu in one day is no small feat. You can take a day off to rest.

I know you want to learn kenjutsu from me, but to truly learn something, your mind must be in optimal condition. You've just accomplished a month's work in one day.

Don't overexert yourself, Kaida. After a day of rest, we can start our training."

Kaida reluctantly nodded, eager to start his training but unable to argue with Yukihiro's reasoning. "Yes, Sensei, but will you personally teach me kenjutsu, or will it be one of your shadow clones?"

Yukihiro smiled, amused. "How did you know I'm a shadow clone, Kaida?"

"Once, you dispersed yourself before I left the training ground, and one of my clones saw you. Not that I mind—I'm perfectly fine learning from a shadow clone."

"Hahaha, as you guessed, I've been using shadow clones to teach you so I can spend time with my cute little daughter. She's just 5 months old and already started crawling. I don't want to miss such an important moment in her life.

Alas, the life of a ninja is not so simple. I have to go on long missions frequently, which is why, when Lord Hokage asked me to train you, I eagerly accepted.

Though at first, I trained you so I could spend time with my daughter, slowly, seeing your dedication, I wanted to teach you seriously. For the next 10 days, prepare yourself for some intense training."

"Yes, Sensei," Kaida replied, more like he was accepting an invitation to an amusement park rather than training hell. Then, he went back home, surprised to see Yomi waiting outside, asleep.

"What are you doing out so late at night?" Kaida asked.

Hearing Kaida's voice, Yomi jumped like a spring and turned around. "Why were you training so late? And why did you scare me like that?"

"Sensei has to go on a mission after 15 days, and since our training period is only three months, I have just 15 days left to learn from Yukihiro-sensei. I want to learn kenjutsu from him, but he said he would only teach me after I learned five elemental jutsu," Kaida explained.

"So?"

"So, I was learning those jutsu. That's why I got so late, Miss So-Smart."

"You learned five jutsu in just one day? How?"

"I've only learned the basics. They can't be used in an actual fight yet, but I'll have enough time to master them after 15 days."

"Still, that's great…"

*GROWL*

Her sentence was interrupted by her stomach growling. Kaida laughed and said, "Hahaha, I haven't eaten dinner either, so let's eat something nice. My treat."

"Okay," Yomi whispered.

After eating, they both went home and slept for 10 hours straight.

Though it was a holiday for Kaida, he still accompanied Yomi to the training ground. After dropping her off, he went to the market and bought 20 pieces of wood. He returned home, made five shadow clones, and began carving swords out of the wood using wind chakra. Since they could now bisect stone, carving wood was easy. It was time-consuming, but he had the whole day, and the task had a therapeutic effect on him. It felt more like relaxing than working.

While Kaida was doing this, Yukihiro was talking to the Hokage about him.

"Lord Hokage, my student has completed his elemental training and has asked to learn kenjutsu from me. He said you told him about my kenjutsu."

"Yes, it's true. You're famous in all five villages for your kenjutsu and are considered S-rank if only kenjutsu is considered. So, I don't think he could find a better teacher than you."

"But Lord Hokage, my kenjutsu technique is only focused on killing. I don't think I should teach such a technique to a child."

"Hmm, do you think Kaida won't be able to handle your technique and might go on a killing rampage?"

"No, Lord Hokage. I believe Kaida has a good head on his shoulders. He always thinks and understands what I teach him rather than just following it mindlessly. But still, I thought I should ask for your permission before teaching him my technique."

"You have my permission, Yuki. Our village is in dire need of a new, powerful, and capable ninja. Training someone of your caliber will help stabilize the village."

"Yes, Lord Hokage."

Yukihiro bowed and returned, planning to enjoy his last full day with his family before taking Kaida's training extra seriously.

Oblivious to all this, Kaida had made 20 wooden swords and 40 shurikens from the wood he bought. At 5, Yomi returned from training. When she saw what Kaida had been doing all day, she was excited. Though she wasn't particularly interested in swords, she was thrilled about the shurikens. Even though they were just made of wood, they were sharp enough to be compared to metal ones.

Though Kaida wasn't particularly tired, he still went with Yomi for an early dinner and slept early, knowing that the following days would be tough.

The next day, they went to the training area at 4:30 AM. Yukihiro was already there, waiting for Kaida. Kaida found it odd and approached Yukihiro.

"Good morning, Sensei. Why are you here so early today?"

Ignoring Kaida, Yukihiro turned to Yomi and said, "Yomi, Kaida won't be returning for three days, so you should continue your training on your own, okay?"

Though she wanted to ask why she assumed it was related to their training and simply nodded.

Kaida was confused, but Yukihiro just looked at him and motioned for him to follow. They arrived at a new training area, different from their usual one. Yukihiro looked at Kaida and asked, "Kaida, what's in the bag you're carrying?"

Kaida opened his bag, and 20 wooden swords fell out.

"Sensei, I made these wooden swords so I can practice kenjutsu with the help of my clones."

"Well thought, Kaida, but kenjutsu also depends on muscle memory, so you'll have to practice on your own as well. The technique will be useless if you can't execute it at the perfect time."

"Yes, Sensei."

"Seeing your dedication, here's something from me." Yukihiro handed Kaida a long rectangular box. When Kaida opened it, he was surprised, happy, and shocked at the same time. Inside was a beautiful Japanese katana, similar to Yukihiro's, but the stark difference was that it was made of normal metal, whereas Yukihiro's swords were made of chakra metal.

Kaida took out the sword and instinctively felt that it was a true masterpiece. Even though it wasn't made of chakra metal, it was still made of a very sturdy alloy that rivaled the strength of chakra metal.

"Thank you very much, Sensei," Kaida said, bowing deeply to Yukihiro.

"Okay, now let's talk about training."
