First, his heart was stitched back together, then his bones rejoined, then flesh was fused. Whether because the injury was too severe or because Unohana wanted him to fully experience Kaidō, the healing took a long time.
About half an hour later, under Gusion's gaze, Unohana's delicate hand passed over his chest and abs, finally stopping at his waist; all visible wounds disappeared.
"So this is advanced Kaidō… It is powerful."
Gusion sighed. "But I feel like, in essence, it's the same as what we learned in class—just your technique is more refined, and you use more spiritual pressure."
Unohana's eyes shone with appreciation and a hint of expectation. "You're very perceptive. Indeed, Kaidō isn't ranked by level. Its strength depends on your control, which improves with practice—and talent."
"I think I get it. Let me try."
Gusion stood, looking at his ruined uniform—he only had one, so he'd have to borrow one from Sōsuke tomorrow.
He went to his desk, grabbed his terrified mouse, and quickly cut open its chest.
Then he invoked Kaidō, closing his eyes to heal it.
Imagine its uninjured form…
Control the reishi more delicately, like threads…
Five minutes later, Gusion looked thoughtfully at the now-dead mouse.
"Your technique isn't bad, but your efficiency is too low. A fatal wound won't give you that much time."
Unohana critiqued from the side.
After thinking it over, Gusion stepped back and looked at Unohana. "Unohana-sensei, let's do it again."
"Oh?"
Unohana was a bit surprised but understood. "You do want to learn Kaidō for combat."
Another blood fountain. Even though Gusion was ready this time, he still couldn't see Unohana's move.
Unohana watched Gusion, lying beneath her, carefully experiencing her technique. She was glad she'd come today; this young man she'd picked up from the slums had given her many surprises.
She'd invited him on intuition, feeling he was the same type as herself.
Like beasts meeting on the savannah, one look was enough to know the other's ferocity.
But Gusion surprised her again and again—kendo, hakuda, shunpo, kidō, he was a genius in all of them. And his reason for learning Kaidō was the same as hers.
How could she not teach him?
North Rukongai District 80—Zaraki District—really did produce talent. She'd once met a terrifying child there who changed her forever, and now she found Gusion.
She didn't know where that child wandered now, but Gusion was a promising new star.
Looking at his handsome, masculine face, she couldn't help but smile. How far will you go to please me in the future?
...
As the sun set, another day ended for the academy students. In the Kaidō classroom, Gusion was thoroughly fulfilled in a learning sense—but physically drained.
When the classroom door opened, the student on cleaning duty was stunned. It looked like a murder scene!
Blood was still dripping from the ceiling, and the floor was drenched. The air reeked of blood.
There were two people in the classroom—one he recognized as everyone's favorite, Unohana-sensei, who was currently stroking the abs of a male student…
Nice body… Wait, what am I thinking?
No, wait, what am I seeing?
In a crime scene classroom, the most popular Kaidō teacher Unohana was caressing a shirtless student's abs.
Creak—!
He closed the door.
It must be that he'd opened it the wrong way and saw it wrong.
Creak—!
When he opened it again, the two were separated—one giving him a strange look, the other wearing her usual gentle smile.
"Um… Unohana-sensei, I… I didn't see anything."
He stammered, turning to flee the scene of the crime. Damn, why was it his turn for cleaning duty today?
But just as he turned halfway, Unohana called out, "Sorry for giving you extra work. We were just practicing Kaidō."
"Practicing Kaidō?"
The student glanced at the cages of white mice, thinking, Could a mouse bleed that much?
Also, the male student by Unohana's side looked so pale he could barely stand. Is that also a result of practicing Kaidō?
The blood… Was it his? No way, Unohana-sensei is so gentle—how could she have students practice on themselves? I must be overthinking.
He grabbed his broom and mop, trembling as he entered, "So… I'll start cleaning?"
"Thank you, senpai."
Gusion apologized as well, not worried about misunderstandings, just feeling bad for how hard the blood would be to clean.
He'd wanted to help, but he was feeling so weak.
Kaido wasn't omnipotent—Unohana could heal his wounds, but not replenish his blood.
She'd had him experience it three times in a row; even his iron body couldn't take that much blood loss. He needed to go to the cafeteria to recover, fast.
"Well, that's all for today. The Next Kaidō class is the day after tomorrow. Prepare well."
Unohana walked lightly across the bloody floor, looking back with a gentle smile, "Next time, I'll be stricter."
Gusion rubbed his chest, wondering if Unohana-sensei might accidentally kill him one day.
He realized that graduating early would be tough. He'd have to satisfy every teacher in every required and chosen class. Without all their approval, speedrunning graduation would be impossible. Who knew if the academy would arrange some special test for a genius wanting to skip grades, too?
Gusion passed the dazed cleaning student, shaking his head and putting all those thoughts aside.
His biggest priority now was to get to the cafeteria and regain his blood. He had no wounds now, but his life value was only 40%.
