"Is it... over just like that?"
Tsunade had also arrived at the scene.
Seeing Kaguya in her current state, she immediately understood what Kaguya had just experienced.
That extremely improper "Medical Ninjutsu" of Seiryū's.
Tsunade had experienced Kaidō herself.
Putting aside its formidable healing ability, the side effects of Kaidō were truly terrifying.
It could practically render someone unable to resist.
Unexpectedly, even the Rabbit Goddess and Progenitor of Chakra, Kaguya, had been unable to withstand it.
"Hmm. To be honest, even I didn't expect Kaidō to work this well."
Seiryū gave an awkward laugh.
He had always known about Kaidō's "side effects."
But the fact that even someone at the Kekkei Mōra level could not withstand them was somewhat beyond his expectations.
This technique was just too improper!
Who exactly had developed this kind of Kaidō in the Bleach world?
Could it have been the Fourth Division Captain, Retsu Unohana?
Hiss!
Something about that possibility felt very wrong!
Tsunade fell silent.
With Seiryū's strength, defeating a weakened Kekkei Mōra-level opponent should not have been difficult, and she had confidence in him.
But ending the battle like this.
No matter how she looked at it, the whole thing felt bizarre!
This technique, Kaidō, was far too dangerous.
For some reason, Tsunade even felt a little sympathy for Kaguya after she had encountered a freak like Seiryū.
"How do you plan to deal with her?"
Tsunade quickly returned to the important matter.
Her beautiful eyes swept over Seiryū.
"Don't tell me you actually have... those kinds of intentions toward her?"
This brat was hardly innocent.
He had made plenty of bold claims about such things before.
Seiryū shook his head.
"Feelings have to be mutual. I generally don't force people. Haven't you noticed that I don't even bother Konan-senpai?"
"Besides, that old man, the Sage of Six Paths, entrusted her to me. Since I've already accepted the favor, I promised to take responsibility for the rest of her life."
"I can't go back on my word."
"I have to reform her through 'love and kindness'!"
Tsunade's mouth twitched.
This brat really had some nerve.
He was even setting his sights on the Rabbit Goddess, Kaguya.
Mutual feelings?
Love and kindness?
He could make it sound as righteous as he wanted, but Tsunade knew perfectly well what kind of ideas were running through his head!
Kaguya tilted her head in confusion.
She did not understand what the two of them were talking about.
What feelings?
What did mutual mean?
Having lived with little understanding of ordinary romance, Kaguya knew almost nothing about love.
Even though she had two children, she was practically a blank slate when it came to romantic relationships.
Those two children had been born from her power.
"Hiss."
Black Zetsu, however, had spent many years hiding throughout the shinobi world.
Its understanding of such matters was far greater than Kaguya's.
After hearing their conversation, it suddenly realized something.
It sucked in a sharp breath, its pitch-black face filling with horror.
Wh-what did this mean!?
That rebellious son, the Sage of Six Paths, had actually entrusted Mother to Seiryū?
Th-this.
Did Seiryū want to become its father!?
Absolutely not!
Kaguya hovered several centimeters above the ground, her bare feet beneath her robe never touching the dirt.
She looked at the two people in front of her and asked in a low voice, "What exactly do you intend to do with me?"
"If you intend to seal me again, then even if I die, I will resist until the end!"
Her words sounded fierce, but her voice lacked conviction.
Seiryū had defeated her but had not sealed her.
What exactly did this descendant of Hagoromo intend to do?
"We have a common enemy."
Seiryū looked at her.
"Isshiki is about to reach the Kekkei Mōra level, and possibly without the weaknesses you currently have."
"So I need you to help me train."
Seiryū's gaze briefly passed over Kaguya's bare feet.
He could not help admiring them inwardly.
If he had to rank them, they would definitely be number one.
Even more beautiful than Tsunade's!
As expected of a goddess.
Perfect from head to toe.
"Train?"
Kaguya frowned slightly.
As a member of the Ōtsutsuki Clan, she barely understood the concept.
The Ōtsutsuki were born with tremendous power.
Their primary method of becoming stronger was consuming Chakra Fruits.
As long as the quality and quantity of Chakra Fruits were sufficient, one could eventually reach Kekkei Mōra.
Training?
What was that?
Seiryū nodded.
"I need to understand the fundamental nature of Kekkei Mōra so that I can reach that level myself."
"You are already Kekkei Mōra, so you can help me."
"I don't understand such things," Kaguya replied.
Seiryū revealed a sinister smile.
"It doesn't matter whether you understand."
"I have my own methods."
Kaguya inexplicably shivered.
She suddenly had the feeling that this descendant of Hagoromo intended to do something even more excessive than sealing her.
However, she was already his captive.
It seemed she could not resist him anyway.
Kaguya lightly bit her lip, looking both wary and uneasy.
"You... what exactly are you planning to d-do?"
The psychological impact of Kaidō had been too great.
It was so severe that she could barely bring herself to think about resisting him again.
Seiryū revealed an exaggerated villainous smile.
"Hehehe. You'll find out later."
"You can't resist me anyway. Hehehe!"
Kaguya's body trembled.
She instinctively retreated several steps.
"You."
Black Zetsu looked completely despairing.
Could it be that this man actually intended to do something terrible to its pure Mother?
No!
How could he dare!?
Mother was a goddess.
The noblest and purest goddess!
This descendant of Hagoromo actually wanted to corrupt its beautiful Mother?
And become its father!?
This was too much!
Mother had only just escaped from her seal, and now she had encountered someone even more troublesome than those two unfilial sons, Hagoromo and Hamura!
She had escaped one disaster only to fall straight into another!
It was over.
Everything was truly over now.
'Smack!'
Tsunade slapped Seiryū on the back of the head.
"Enough. That expression doesn't suit you at all. You just look ridiculous."
Ignoring Seiryū's dissatisfied expression, Tsunade adopted the dignified bearing of the Hokage and looked toward Kaguya.
"The reason you're still alive and haven't been sealed is because you can still help us."
"I hope you don't do anything foolish."
Kaguya was worth bringing onto their side.
After all, she was both a member of the Ōtsutsuki Clan and a Kekkei Mōra-level existence.
Apart from Isshiki in the shinobi world, there was also the threat posed by the Ōtsutsuki Clan beyond this planet.
The shinobi world needed to prepare for that possibility.
At the very least, they needed reliable information about the wider Ōtsutsuki Clan.
Kaguya possessed that information and was therefore an invaluable source of intelligence.
Moreover, Seiryū had already said that he wanted to reach Kekkei Mōra through his own power.
A living Kekkei Mōra-level existence was extremely useful for that purpose as well.
"Hehehe. Just remember one thing."
Seiryū once again put on an evil grin, looking like some terrible villain threatening a helpless captive.
"You're my prisoner now."
"If I need your cooperation, then cooperate."
"And if you refuse, don't forget that my Kaidō isn't just for show."
