The linear Spiritual Pressure blades pierced through the defense line of the blood blades, leaving several bloody marks on Retsu Unohana's body.
"Kuruyashiki's move... you learned it after just one look..."
Blood mist rose from the wounds on Retsu Unohana's body, and they healed rapidly.
"All changes remain true to their original nature," Sora laughed. "You are known as 'Yachiru', so you should be able to do it too."
With Sora's current level of swordsmanship, he could basically learn this kind of sword technique with just one look.
And since Retsu Unohana used to boast about mastering all styles and sword flows in the world, earning the name 'Yachiru' (Eight Thousand Styles), she should also have this ability.
"Of course."
Retsu Unohana bent down slightly and inserted her Zanpakutō into the blood pool.
In the next moment, a wave of blood suddenly rose.
When the blood wave rolled up, it turned into thin red threads, shooting towards Sora rapidly.
Both of them incorporated their own understanding while using Kenpachi Kuruyashiki's move, improving this close-range slashing move into a long-range attack.
The blade in Sora's hand turned into an afterimage, blocking the incoming linear Spiritual Pressure blades.
The power of these linear Spiritual Pressure blades was average, but their advantage lay in their numbers; a large amount of them could be unleashed in a short time.
Splurt—
A thin red thread landed on Sora's shoulder, cutting a wound.
But under the effect of the self-healing Kidō, this flesh wound healed quickly.
The attack just now was merely Retsu Unohana's cover. By the time Sora finished dealing with the blood threads, she had already arrived at his left side.
More than ten crescent-shaped blood blades passed through Sora's body.
But that figure disappeared quickly—it was just an afterimage!
Immediately after, seven Sora Katoris appeared around Retsu Unohana, slashing at her simultaneously.
The seven Soras blocked all her retreat routes, leaving absolutely no room to dodge. But Retsu Unohana swung out more than ten crescent-shaped blood blades again at extremely high speed, slashing towards the Soras surrounding her from all directions.
The Soras pierced by the blood blades all turned into afterimages and disappeared.
"All feints!"
Retsu Unohana looked up. The real Sora Katori was right above her head!
With a flash of sword light, a burst of blood mist exploded from Retsu Unohana's neck.
"It seems that before your Spiritual Pressure is exhausted, the blood mist here will continuously heal you, even achieving an effect similar to a Hollow's High-Speed Regeneration."
Sora saw some blood mist rising from the wound on Retsu Unohana's neck.
This should have been a fatal wound. If not treated with Kaidō, Retsu Unohana should have breathed her last very quickly. But now, it was healing rapidly.
In the blink of an eye, the fatal wound on Retsu Unohana's neck had completely healed.
Retsu Unohana didn't intend to stop fighting before exhausting her stamina. She continued to attack with her sword.
The blade slashed across the blood pool, bringing up a turbulent flow of blood.
With a wave of the blade towards the sky, the blood turbulence turned into a sky full of blood rain.
Each drop of blood rain was enough to penetrate a mid-level or higher defensive Bakudō!
Retsu Unohana didn't stop her movements.
The blade slashed across the blood pool again, raising another turbulent flow of blood.
The blade edge wrapped in blood turbulence flipped in the air and turned into a blood tornado.
In the next moment, following closely behind the blood rain, the blood tornado pressed down fiercely towards Sora from top to bottom.
Sora quickly drew 'Tenzui Shinkotsu' from his waist.
Spiritual Pressure gathered on the dual blades, striking out a cross-shaped crescent moon.
The blood rain fell on the cross-shaped crescent moon, creating some pockmarked holes on it.
But that was all. After the cross-shaped crescent moon swallowed the blood rain, it met the blood tornado.
Boom—!!!
After the collision, the cross-shaped crescent moon severed the blood tornado, while the blood tornado simultaneously tore apart the cross-shaped crescent moon.
The cross-shaped crescent moon and the blood tornado in the air dissipated almost at the same time.
Meanwhile, Sora lunged and raised his sword, pressing his left hand on the back of the blade, attaching Spiritual Pressure to the blade body.
Then, stepping forward fiercely, he thrust out a sword strike at extremely high speed.
Katori Style · Shungeki!
A heavy sword has no sharp edge; great skill needs no work.
The terrifying Spiritual Pressure gave this sword thrust the power to penetrate almost anything.
Retsu Unohana's mouth opened slightly, and blood flowed from the corner of her mouth.
Sora's sword had already pierced through her heart.
"So pleasant..."
Retsu Unohana savored the pleasure of the blade kissing her skin, the smile on her face widening a bit more.
The battle of walking on a tightrope on the edge of life and death caused the synapses between her neurons to release excitatory neurotransmitters. The ripples they stirred up in her mind were like a surging torrent, breaking through obstacles and finally converging into a roaring waterfall, filling every inch of space in her body.
The rising blood mist tried to heal Retsu Unohana's wound, but her Spiritual Pressure was dropping rapidly. The blood mist in the shadow space gradually dissipated, and the blood pool on the ground also dried up quickly.
It couldn't be healed!
Retsu Unohana's Spiritual Pressure had weakened to the point where she couldn't self-heal a fatal wound!
However, besides Retsu Unohana, there was another master skilled in Kaidō in this place.
Sora held Retsu Unohana's waist with one hand and pressed on the wound on her heart with the other, quickly treating her with Kaidō.
A moment later, Sora pulled a wisp of shadow out of Retsu Unohana's wound.
The Shungeki he used just now was stabbed with a blade transformed from shadows, so Retsu Unohana wouldn't suffer secondary damage from pulling out the blade. He could even use the shadow to suture the injured heart.
Sora could now perform surgery inside the body using his shadow ability through a minimally invasive wound.
"Your medical skills are also above mine..."
After treatment, the trauma to Retsu Unohana's heart had been repaired by Sora.
And the heart trauma repair surgery was completed while Retsu Unohana was awake!
If anyone else from the 4th Division came over, they would think this was simply a medical miracle!
Subsequently, under the effect of Kaidō, Retsu Unohana's heart recovered as before.
Just as Sora intended to heal the wound on the skin as well, Retsu Unohana grabbed Sora's hand, interrupting his treatment.
"Leave this wound on me. I want to remember the feeling just now."
Retsu Unohana seemed to recall the feeling of Sora's blade entering her body again, and some color returned to her pale face.
...
Early the next morning.
In Retsu Unohana's courtyard, many Shinigami were constantly coming and going.
When passing by the Captain's room, they looked around inside, trying to see the situation within. They all wanted to know why Captain Katori and Captain Unohana stayed in the room all night.
Unfortunately, the tightly closed door shut out all sight.
"Captain Katori and Captain Unohana stayed in there all night!"
"More than just all night... They went in at dusk."
"Isane, why don't you go take a look?"
"Ah! No!"
Isane Kotetsu shook her head repeatedly. Although she was also very curious why Professor and Captain stayed in the room for so long, she didn't want to disturb them rashly.
"Professor should be sparring with Captain... right?"
Isane Kotetsu's voice became somewhat uncertain.
It was hard for her to explain what kind of sparring required fighting all night.
Just then, the tightly closed door suddenly opened, and Retsu Unohana walked out of the room.
Everyone looked behind the Captain, but soon looked disappointed; no one followed behind the Captain.
They saw the Captain keeping her hair down over her shoulders and felt a bit unfamiliar.
"Captain, Captain Zaraki... and Lieutenant Kuruyashiki's injuries have been treated," Isane Kotetsu mustered up the courage to ask. "Where is Professor?"
"He has already left."
Retsu Unohana still had that gentle look from the past, but the Shinigami of the 4th Division all had the illusion that the Captain was particularly cheerful today.
