"Why?"
Anko instinctively asked. Kurenai immediately provided the answer.
"Isn't it for you! With this relationship between him and me, if he regrets it later, I can persuade him."
Although Kurenai said it was for Anko, what came to her mind was Ryun's strong, sensible demeanor, and the way he kept calling her 'Sister Kurenai'. "Thank you, Kurenai. You are too good to me!"
Hope also rose in Anko's eyes.
Then, Kurenai sent Anko out to buy a bunch of food suitable for a patient, planning to let Ryun have a full meal first, then solve this troublesome matter all at once.
By the time Ryun sat down at the table, Anko, who had used the Body Flicker Technique all the way, had also rushed back.
She didn't dare to look Ryun in the eye, shoved all the things in front of him in one go, then immediately returned to sit opposite him in a deep bow, prostrating herself on the floor, wishing she could shrink into a ball.
Kurenai spoke first. "Nojuro, whatever decision you make, I guarantee you will not be threatened or harmed again."
Anko immediately felt immense pressure. What if Ryun said he wanted her to die now?
Ryun pretended to have an internal struggle before speaking. "Sister Anko, can I call you that?"
"?! Yes, of course you can!"
Anko felt like she heard heavenly music, but Kurenai frowned.
She had witnessed Ryun's most lonely and helpless side, and had shown him her true feelings, which only then earned her the title 'Sister Kurenai' from him.
Why should Anko get to be called 'sister' by Ryun?
Ryun continued. "Sister Anko, I know you acted recklessly under the influence of alcohol. That wasn't your true intention."
"I don't want to hold a grudge against you, but I also cannot pretend yesterday never happened."
"After careful consideration, I've decided to treat yesterday's incident as a misunderstanding. From now on, let us address each other as siblings. What do you think?"
Kurenai's frown eased. She understood Ryun's intention.
Anko could transform the apology in her heart into compensation for Ryun under the name of being siblings.
Ryun could also use the sibling relationship to prevent their relationship from deteriorating and being harmed by Anko, a Special Jonin, again.
It was just a very smart and practical approach, but so practical it made Kurenai's heart ache.
Anko rubbed her hands uneasily, muttering to herself. "Is that enough?"
"That is enough." Ryun said firmly.
Anko nodded, but her earlier happiness was gone.
Ryun forcibly ended this matter, but she couldn't forgive herself in her heart.
Seeing that the mood was about right, Ryun spoke up. "But Sister Anko, there's one thing you must promise me."
"Okay, yes! In the future, Nojuro, little brother, you can come to me anytime for anything, I'll do whatever you want!"
Anko expressed her attitude enthusiastically. It seemed she could only slowly make up for the guilt in her heart through this kind of concern from now on.
"Ahem, this matter..."
Ryun hesitated. Seeing this, Kurenai immediately stated her position. "Nojuro, you can bring up any conditions. I'll stand up for you."
"Alright then."
Ryun looked at Anko and said, "Sister Anko, did you take contraceptive measures? I don't want a child yet."
Anko blinked, her face visibly turning red.
In terms of age, she could indeed be Ryun's sister, but in such matters, Ryun's theoretical experience was countless times richer than hers.
She stammered, "Contraceptive measures... of course I already... haha, it's been so long since it ended. Even if we use contraception now, it's too late, right?"
Kurenai covered her face with one hand. Ryun also looked stunned.
Anko said in self abandon, "I've never had a boyfriend. Is it weird that I don't know about these things?"
"Then should I teach you?"
Ryun tentatively suggested. Kurenai couldn't sit still anymore. She grabbed the back of Anko's collar, pulled her into the guest room, and closed the door.
Within seconds, sounds of a commotion came from the guest room. Clearly, Kurenai couldn't help but take action against Anko.
Anko didn't dare to scream, only endured Kurenai's anger.
Half an hour later, Kurenai walked back to Ryun's side with a radiant smile. She picked up a chicken leg and put it into Ryun's rice bowl, saying, "Here, Nojuro, eat your fill to regain your strength."
"What about Sister Anko?"
Kurenai rolled her eyes. "When it's just the two of us, just call her by her name."
"Don't mind her. She has endurance like a snake. She won't die easily."
For the rest of the afternoon, Ryun didn't see Anko again, only sensing that she had slipped away through the window.
This also meant the night assault incident was completely over.
Ryun avoided the awkwardness of having a child next year and also gained two sibling bonds, although this sibling relationship seemed somewhat strange.
But precisely because of this bond, it should become effortless for Ryun to obtain a higher level Natural Energy Adaptation talent from Anko next time.
After finishing the meal, Kurenai left the house.
She took the mission invitation letter written by Ryun and personally delivered it to the Hokage's office, accepting the mission to help Ryun maintain order at his book signing event.
However, the asking price changed from the initial 300,000 ryo for an A rank mission to the starting price of 5,000 ryo for a D rank mission.
Ryun naturally wouldn't refuse such an obvious compensation from Kurenai. While Kurenai was out, he began attempting to use the Flying Thunder God Technique.
The Flying Thunder God Technique actually consists of three steps.
First, use special chakra to imprint the Flying Thunder God mark on a target, or write the Flying Thunder God formula on paper.
Next, the ninja must use their sensory ability to perceive the existence of the mark. Finally, use a method similar to Reverse Summoning to teleport themselves to the mark.
Looking just at the principle, the Flying Thunder God Technique doesn't seem particularly difficult.
But in reality, this technique has extremely high requirements for a ninja's Space Time Ninjutsu talent, Chakra Sensory talent, Sealing Techniques and Cursed Seal Techniques, adaptability, physical fitness, chakra amount, and even combat ability.
From this perspective, the Flying Thunder God Technique is less of a single ninjutsu and more of a mature combat system.
If any part of this system is missing, then the Flying Thunder God Technique degrades into a long distance teleportation jutsu.
Naturally, Ryun didn't dare claim he could use Flying Thunder God in actual combat yet, but using it as a convenient and quick teleportation technique should certainly be no problem.
Ryun closed his eyes, concentrated chakra in his palm, and a chakra mark slowly formed on his hand.
The Sealing Techniques and Cursed Seal Techniques Ryun studied during his time as a medical ninja now came in very handy. He barely paused at this step.
Next, Ryun flipped his wrist and pressed his palm onto the floor, leaving a Flying Thunder God mark identical to Tobirama Senju's on the floor.
Then, the mark slowly disappeared before Ryun's eyes, entering a latent state.
Someone without sufficiently strong Space Time Ninjutsu talent wouldn't even detect its existence.
In theory, it wouldn't disappear unless erased by another person who knows the Flying Thunder God formula, or forcibly removed by a higher power.
Of course, directly smashing the floor into powder would also cause the mark to fail, as the mark itself is just chakra.
Then, Ryun formed hand seals to expand his sensory ability, attempting to perceive the mark's existence.
Before doing this step, Ryun actually felt somewhat apprehensive.
His Chakra Sensory talent was only Intermediate level, with a range of about one kilometer.
It might be enough for usual combat, but for using Flying Thunder God, wasn't that too short a distance?
But the next second, a hint of pleasant surprise appeared on Ryun's face.
Now he finally understood why the Flying Thunder God Technique's requirement for Space Time Ninjutsu talent was so high.
Because the process of a ninja sensing this mark relies not just on Chakra Sensory ability, but also heavily on the ninja's Space Time Ninjutsu talent!
In some intangible way, a three dimensional world coordinate system seemed to appear in Ryun's mind. Everything in his memory integrated into this coordinate system and could extend outward infinitely.
The mark he engraved was within this coordinate system. It felt like no matter how far away, Ryun could grasp its position and transfer there!
This explained the principle behind Flying Thunder God's ability to transfer beyond sensory range, and also explained why the technique itself was dangerous.
Performing an ultra long distance transfer was like closing your eyes and charging headlong into enemy territory. Someone without skill doing this was no different from seeking death.
Now everything was ready, only the transfer remained.
Ryun slowly stepped back, moving near the wall. Then, the chakra within his body surged wildly.
The next moment, Ryun disappeared from his original spot.
It felt like squeezing into a narrow space, then being spat out in one breath.
Ryun's hand landed, accurately pressing onto the Flying Thunder God mark he had just left on the floor.
Success!
After the Fourth Hokage, Namikaze Minato, Ryun became Konoha's next person to successfully perform the Flying Thunder God Technique entirely on his own!
