Yakumo Kadori perceptively saw Arata's good intentions and knew he wanted to comfort the hurt Isane, but she still kindly advised him: "Young Saito, Isane-chan isn't a fragile little girl, don't underestimate her."
When Isane saw Arata approaching, she quickly wiped the corners of her eyes with a tissue and forced a smile: "I'm really sorry, I made Saito worry. You don't have to force yourself to comfort me. It's just… I'm not used to this situation…"
Arata smiled bitterly and shook his head, realizing that his actions had been misunderstood. He seriously explained: "Actually, it's not what you think. I really do have some questions about Kaidō that I'd like to ask you."
As he spoke, Arata opened the notebook in his hand and showed the notes he had carefully taken while attentively listening to the lecture.
"For example," Arata's finger tapped on the damp ink, "about what you just said on the principle of applying the rotational flow of spiritual pressure in Kaidō. I have questions about that part. Why is clockwise rotation assumed rather than counterclockwise?"
"Also, due to the lack of fine control techniques for spiritual power, there was a loss of spiritual pressure during the healing process. Although you didn't mention it, Miss Isane, I think we should refer to the multi-person spiritual pressure sharing techniques from Medical Report No. 9527 of the 4th Division."
"And here…"
Yakumo Kadori curiously looked closer at Arata's notes, and a surprised expression appeared on her wrinkled face: "Wow, you even derived the loss formula for spiritual pressure circulation. This isn't taught at the Spiritual Arts Academy. Young Saito, haven't you been secretly studying Kaidō on your own?"
Arata scratched his head and smiled shyly: "Yakumo-san, you're teasing me. I know a little bit of everything. These theories are often mentioned in the 4th Division's medical reports. Out of curiosity, I read them a few times and naturally learned."
Some time ago, out of interest, Arata went to Yamada Hanatarō to learn a bit about Kaidō, and the cost was paying for his lunch for a week.
On one hand, after integrating the Spirit King's bloodline, Arata's efficiency in learning various types of knowledge had increased greatly. Learning one more field was still learning, and there's an old saying from our ancestors, the more skills, the better.
On the other hand, he couldn't always place his life and death in others' hands. Even if Unohana Retsu was a top doctor, it was impossible for her to be by his side in every battle and heal him.
There would always be moments when you have to fight alone, and in such situations, mastering recovery techniques is extremely important.
Isane, who was still in a dazed state, was bombarded by Arata's string of professional questions and concepts. She was briefly speechless, her silvery-gray lashes trembled, and her facial expression became increasingly rich.
She didn't expect that this young man with outstanding talent in kendo actually listened so attentively to her Kaidō class, which was boring to everyone else.
The dense notes in the margins were even more detailed than the lesson plan she had prepared.
Guided by a sense of responsibility as a medical Shinigami and encouraged by Arata's personal charm, Kotetsu Isane took a deep breath and quickly composed herself.
She moved a little closer to Arata to better see the handwriting in his notebook. "Saito-san, this question about rotation and the flow of spiritual pressure you mentioned is actually like this…"
"In most cases, the mastery of Kaidō by medical Shinigami by no means reaches the standard needed to achieve counterclockwise rotation, so…"
"I understand. Then in this part…"
"…"
Yakumo Kadori, watching them immersed in study and discussion, smiled and tactfully left the classroom, considerately closing the door, then sighed with a smile as she walked away.
"Ah, it's wonderful to be young!"
Arata's understanding of Kaidō was deeper than Isane had imagined, so their discussion stretched until sunset.
[The fate of Kotetsu Isane has shifted thanks to your actions, you gain 108 destiny points.]
To repay Isane for her help in clarifying his questions, Arata planned to invite her to dinner, but Isane said Rangiku had already invited her in the morning and politely declined Arata's invitation.
So Arata had to go to the Ōmaeda hotel alone to settle dinner.
After dinner, Arata returned to the Kendo Club and noticed the lights were on inside, and from time to time the sound of wooden swords clashing could be heard.
Who's still practicing in the Kendo Club this late?
He opened the door and entered, seeing Renji and his three companions currently sparring in pairs.
"I was wondering who was still training this late in the Kendo Club, turns out it's you four." A satisfied expression appeared on Arata's face. After teaching kendo classes for more than two weeks, he was already half their teacher.
Seeing them working diligently even at this hour, he had to take his hat off to them from the heart.
He had previously heard some news from Shūhei: ever since Renji and the others joined the Kendo Club, their overall performance had been steadily rising. In the first round of training, they all made it into the top ten, even outperforming some students from the noble class.
Even Vice Dean Shibato personally stated that these people were probably the new generation of talented youth in the Shinō Spiritual Arts Academy after Arata.
"Senior Arata!" ×3
"Boss, my zanjutsu has improved rapidly these days. Kira can't beat me anymore, hahaha!" Renji, who had just won a match, ran up to Arata happily, as if seeking praise.
"Renji, you little rascal, I told you not to call me boss."
"Alright, boss!"
At that address, Arata immediately had a stress reaction.
He'd told him many times, but Renji never changed his tone and kept calling him boss.
"Teacher" didn't sound close enough, and "senior" wasn't impressive enough.
Only "Boss" fit the tall and mighty image of Arata in Renji's mind.
Whatever.
Due to the training course activities, Arata hadn't been coming to teach in the Kendo Club these days, so Renji and the others could only practice on their own.
Out of a sense of responsibility and the desire for destiny points, Arata decided to give them a make-up lesson tonight. "Today I'm going to teach you a new technique. It's very difficult. Are you mentally prepared?"
"No problem, boss!"
"Senior Arata, what skill are you going to teach us?" Hinamori asked curiously.
"Isn't it… that same slash the senior used during the internship?" Kira thought for a moment and recalled one possibility.
"Really?!" Rukia was surprised. She still clearly remembered that night, how senior Arata swung, and several purple-black moon slashes easily destroyed an invisible group of Hollows.
Arata nodded and smiled: "Of course not. That move is still far beyond your reach right now. The spiritual pressure in your bodies is by no means sufficient to support using that move."
"Heeeey——" the four let out strange cries in disappointment.
However, Arata immediately changed the topic, with a mysterious look on his face: "But, what I want to teach you today is the preparatory technique for that move, the method of attaching spiritual pressure in your bodies to the blade."
"It's called — Kenatsu!"
