Chapter 321 Surveillance Shift
Edited by: Kanaa-senpai
Fortunately, the elders did not forcefully demand a sacrifice; Nonaka Yuki and Nonaka Kurumi eventually discussed it and decided to play it by ear.
When they actually saw Aki, the sisters felt the elders’ requirements were not that hard to accept after all.
Nonaka Yuki’s heart wavered; she bit her red lips, looking unsure.
Even though she was very curious about Aki’s ‘Dual Cultivation Ability’1 and her body was constantly sending signals of desire, she still could not bring herself to offer her precious first time for this.
Just then, Aki suddenly let go of her.
”I am not using information as a condition to force you,” Aki said calmly.
He reached out and pinched the girl’s round, beautiful buttocks, taking a small liberty, before pulling his ‘Great Dragon’ out from between her legs.
Aki pulled up his pants and, while fixing his clothes, said, “Dual Cultivation Ability is not some secret; I can tell you all about it, but whether you believe it or not is up to you.”
Except for ‘Talent Copy Talent’ and the skill’s ability, the ‘side effect’ of the Dual Cultivation Ability making women unable to leave him was not a secret.
It was just that many people did not believe that such a powerful ability actually had no downsides.
Nonaka Yuki might believe it, but those elders of the Hero Village would most likely not listen to Aki’s one-sided story.
Nonaka Yuki’s beautiful eyes were wet, almost ready to drip; the moment the hot ‘Great Dragon’ was pulled away, while she let out a sigh of relief, a strange sense of disappointment surged in her heart.
”Why?” she asked in a low voice.
”Why what?” Aki asked.
Aki finished dressing and started cleaning up the gym storage room, taking the opportunity to wake up the four girls including Hamazaki Reina who were still lost in the afterglow.
Gym class was about to end, and everything had to be cleaned up before then.
”Why don’t you use this to threaten… to make a deal with me?”
Nonaka Yuki originally wanted to say threaten, but felt it was not quite right.
She was confident that she was a top Schoolgirl, not worse than any girl around Aki, so why did Aki not want to do something with her?
Aki saw through what this cold Hero Schoolgirl was thinking at a glance.
”Because I am very greedy; I don’t just want your body, I also want your heart,” Aki said.
Nonaka Yuki’s breathing hitched, and it was a long time before she said, “I only act according to the village’s instructions; aren’t you afraid that I will betray you?”
Aki gave her a sidelong glance; he knew, this Schoolgirl who looked cold on the outside had a very stubborn personality on the inside.
If he truly obtained Nonaka Yuki’s heart, never mind the village, for Aki’s sake, she might even be able to turn against her own sister.
”Not afraid, you can’t beat me,” Aki said.
Aki paused for a moment and added, “Those old guys in your village also can’t beat me.”
Nonaka Yuki remained calm on the surface, but in reality, her emotions were swirling violently.
Looking at Aki’s undisguised desire and confidence, the original awkwardness and resistance in the girl’s heart quietly disappeared.
If Aki wanted to do something with her right now, she definitely would not hesitate.
Unfortunately, Aki could not read minds.
Looking at the clear liquid between the girl’s legs, he teased, “Yuki, besides Dual Cultivation, there are many other ways to solve the problem; do you want to try one first?”
If Dual Cultivation could still use the mission as an excuse, other ways of intimacy and pleasure could only be based on having feelings for each other.
These feelings did not necessarily have to be love, but at the very least, it was a good impression.
Aki originally thought that Nonaka Yuki would refuse, but instead, he saw the girl gently nod her chin.
Just as he wondered if he had seen wrong and intended to ask again, the bell for the end of class rang.
”Yuki… forget it, let’s go,” Aki said.
Aki pushed his doubts aside; there were many opportunities, no need to rush for this moment.
Soon, it was time to leave school.
Aki left the School together with Yomisawa Tsukino and Sakuramachi Touko, and Nonaka Yuki followed closely behind him.
”Hmm?” Nonaka Kurumi looked at her sister’s figure, and a sound of doubt escaped her small mouth without thinking.
She looked the same as before, but it seemed like something was different.
After staring carefully for a while, she noticed that the distance between Nonaka Yuki and Aki seemed to have become closer, and her position had also changed a bit.
Originally, she had always been one step behind, but now she was at his side and slightly behind, and the distance had also shortened.
It was only a very small change, but as sisters who had grown up together, she keenly noticed the problem.
Rather than surveillance, this seemed more like a boyfriend and girlfriend…
Well, not quite at the level of a boyfriend and girlfriend, but they were already close friends of the opposite s*x.
Nonaka Kurumi’s mood was complicated; it had only been three days, and her own cold sister seemed to have already fallen.
As expected, he was a dangerous man.
The petite Schoolgirl with a light Purple Ponytail looked at Aki with eyes that had become watchful, but it soon turned into relief.
This was also not bad; since she had to offer herself, giving her first time to someone she liked was better than giving it to someone she did not like.
In fact, not only did Nonaka Kurumi notice Nonaka Yuki’s changes, Kiba Yuki and other observant girls had all noticed some clues more or less.
Because there were girls around him every day, Aki did not notice it for a while.
But given more time, he would definitely be able to notice it too.
But before that, he might have already made a direct move.
Aki originally wanted to take the opportunity to bring up the gym storage room matter again after the group activity with the three black-haired Schoolgirls, Sakuramachi Touko, Akizono Kanna, and Yomisawa.
As a result, as soon as they arrived at Sakuramachi Touko’s apartment, he suddenly received a message from Rias.
”Touko, sorry, I will make it up to you next time when I have time,” Aki said.
Looking at the resentful expressions of the three Schoolgirls in front of him, Aki was also very helpless; he did not want to leave at this time, but there was indeed something to do.
Although they were unwilling, the three of Sakuramachi Touko knew the importance of things and did not pester him.
Sakuramachi Touko and Akizono Kanna each hugged one of Aki’s arms and kissed his face.
”It’s a promise, next time you are not allowed to stop until you make us unable to get out of bed,” Sakuramachi Touko said.
”Little Succubus, just wait, this Demon King will definitely make you completely obedient,” Aki declared.
Aki had the Devils Lineage, and his strength had reached Super-Devil, so calling himself Demon King while joking was reasonable.
Finally, he hugged Yomisawa Tsukino and kissed her, and Aki then went home with Nonaka Yuki.
After the big mansion was renovated, unless necessary, the activities of the Occult Research Club after school were all carried out at home.
When Aki and Nonaka Yuki returned home, Rias and Himejima Akeno, as well as the Naruse sisters and Nonaka Kurumi were already waiting in the living room.
Aki sat between Rias and Himejima Akeno, and Nonaka Yuki’s steps paused for a moment before she sat next to Nonaka Kurumi.
”Koaki, the document regarding surveillance has come down,” Rias said.
Rias took out a document giving off faint Mana (magic energy). Naturally, such things involving the two worlds could not be recorded in an ordinary way, to prevent anyone from intentionally causing trouble.
”You will still be monitored by Yuki afterwards, for a period of one year.”
”Doesn’t matter, being monitored for a lifetime is also fine,” Aki said as he picked up the document and spoke casually.
When Nonaka Yuki heard this, her body moved quietly, and it seemed as if light was shining from her cold, beautiful eyes.
”Eh?” Aki flipped the document down and asked, “Kurumi’s surveillance target has been changed to Mio?”
”Yes,” Rias said. “That is the reason why I called you all back.”
Naruse Mio did not participate in any club, but she was not a member of the go-home club.
Besides studying, she now practiced hard whenever she had free time, trying to master the power within her body.
Partly to deal with Zolgear who was secretly watching her, and partly because she wanted to be reunited with her parents sooner.
When she was strong enough to protect her family, the Naruse couple would naturally not need to continue hiding in the Gremory household and receiving shelter.
At this time, Rias took out another document, “This is the news that Grayfia just sent over, you all take a look.”
Aki took it first and started flipping through it.
A moment later, he passed the document to Naruse Mio and Maria.
While the others were passing around the document, Aki held his chin with one hand and began to think secretly.
If the Hero Clan wanted to monitor the Demon King’s sister, the next head of the Gremory household, one of the Four Great Devil families, they would inevitably have to discuss it with the high-level officials of the Underworld.
Although there were legitimate reasons, they still could not reach an agreement.
Monitoring Aki was still easy to talk about, but monitoring Rias was a bit insulting to the Devils.
The Devils Peerage was also a Peerage, and they valued face and dignity highly.
The Hero Clan did not insist on monitoring Rias either; anyway, monitoring Aki had about the same effect.
As for monitoring Naruse Mio, it was because of Zolgear.
After the Three Factions Talk, Sirzechs and Serafall had been looking for trouble with Zolgear.
But this guy who was about to die of old age was very slippery, and they could not produce clear evidence; facing this kind of old guy, they could not easily deal a fatal blow.
After tossing and turning for a period of time, it ended with secret surveillance.
