Chapter 37: Nanika I

.......

'Hmm, I scanned her at a cellular level yet she seems normal, perhaps I should try it again when Nanika appears,'

"Yoo, kill, how's your training?" Yasuo then turned to Killua getting him out of his daze.

"Ahm, It's okay" Answered Killua awkwardly. He and Yasuo rarely talk or even meet since the latter spends most of his time in his lab or outside, and even if Yasuo visits, he spends the majority of the time with Alluka or Illumi so they're not close.

"Oni-chan! what happened to her?" Asked Alluka confused while pointing towards Mitsuba's remains.

"Hmm, she just had an unfortunate accident, anyway let's go home," Yasuo noticed a while ago a servant hiding a little bit far with a camera which should relay everything to the surveillance room where the rest of the family should be watching.

After all, the one who ordered Mitsuba to refuse all of Alluka's requests is none other than Kikyo.

Alluka didn't say anything else as she laid her head on Yasuo's shoulder, she looked quite cozy as she dozed off.

Since Yasuo made the vow for increasing his enhancement, the air around him changed making it more peaceful and serene.

This affects anyone close to him making them feel safe and secure which basically gives him the ability to get close to people easily.

....

"kill, you can go to the playroom if you want to play more, I'll send Alluka there when she wakes up," Suggested Yasuo with Alluka still in his arm, Killua just nodded then ran heading to the playroom.

Yasuo entered the family room finding Silva, Kikyo, and Illumi all waiting there. He also noticed that Zeno and Maha aren't anywhere in the mansion so they should be on a mission or just doing whatever they like.

"I'm back." Said Yasuo while taking a seat on the couch.

"Em, welcome back.."

"So. for how long were you watching? did you see it?" Asked Silva.

"Long enough to see everything, so care to explain?" Asked Yasuo while putting Alluka next to him laying on his right shoulder, then he started stroking his earring with a hint of interest in his eyes though only he knew it's faked.

Silva started explaining in a serious tone.

To keep it short, a few days ago, Alluka asked Mitsuba to do three simple things: carrying her, going up a staircase, and raising Alluka up in the air.

After Mitsuba did what she was told, Alluka's eyes and mouth suddenly turned pitch-black. Freaked out by this, Mitsuba called for help. Killua came and changed Alluka back to normal by asking Alluka to make himself go "high-high", which Alluka did.

After the accident, Killua had to tell the Zoldycks about Alluka's secret because Mitsuba had already reported it to them.

It turned out that when Alluka had three requests fulfilled, her eyes and mouth would turn pitch-black, and they would change back to normal only when she heard and granted a wish.

"As for what you saw today, your mother ordered Mitsuba to refuse all of Alluka's requests, and as you saw, Mitsuba died.

Also, a servant informed me that Hassam also died the same way she did at the same time. Lastly, we call the thing Nanika." Silva finished his explanation.

"So, did you use your Hatsu on her?" He then asked.

"Hmm, I did and I noticed no difference, she's completely normal though I haven't tried it when she's in that peculiar state since I was far away."

Since Yasuo sometimes spar with Silva and Illumi, then they know general knowledge about his abilities and he told them that he has an ability that helps scan things which makes sense considering his interest in researching things.

And since he needs to shrink his domain almost completely to create a 15 cm amplification domain allowing him to sense things at a cellular level but he can only use his amplification domain inside the available normal domain.

So when he was observing Nanika in action, he wasn't able to use it.

"From what you said, It appeared that once one fulfills three of Alluka's requests, Nanika will assume control over Alluka's body and grant one wish.

The wish does not have to come from the one who fulfilled Alluka's requests since as you said Killua was able to ask for a wish even though Mitsuba was the one who fulfilled the requests."

Once Yasuo started to talk, all three of them paid their undivided attention to him.

The relationship between Yasuo and his family is something like this:

-Mutual Appreciation and respect between Yasuo and Silva.

-Kikyo is extremely fond of Yasuo and appreciates him, she also considers him to be the perfect assassin while Yasuo simply appreciates her and is thankful to her and this is as far as his feelings can go for her, a mother-child bond isn't something he is interested in.

-His relationship with Killua and Milluki is non-existent as they practically never interact though Milluki seems jealous of how much Kikyo and Silva appreciate Yasuo.

-As for Illumi, he likes him and likes their interactions and he trusts him a little bit considering his personality, and they kinda understand each other.

-Lastly, he is fond of Alluka, he sees her as a cute little sister.

This is why they take his opinions seriously and because of his intellect and ability.

"If that person declines or fails to fulfill Alluka's requests four times, people will die in this case, two people died and they're lovers so the relationships the person has may have something to do with who dies. Lastly, All deaths occur instantly and simultaneously."

Everyone seems to be in deep thoughts for a while as silence enveloped the place while Yasuo just continued to stroke his earring.

After a while, Illumi narrowed his eyes, "Should I take care of it or just use my ability on it?"

"No, we don't know what creature it is nor do we know where it came from, there might be some unforeseen consequences to doing that" Silva directly refused.

"We should experiment on it more, if it's deemed too dangerous then we can lock it up," Added Kikyo.

"Nah, leave her to me, I won't abuse her power since I don't know the price one has to pay for it. After all, according to my observation, abilities work on the concept of equivalent exchange so the question is what's the price." Stated Yasuo calmly

Silva and Illumi both narrowed their eyes, "It could be useful to the family and if she asked you for something you can't do then all of us will be in danger, so it's better if it's looked up." State Silva in a resolved tone while Illumi seems to agree.

Yasuo looked at this calmly with a serene smile on his face, he turned his face looking at Alluka since he noticed her waking up.

Yawn!

"Good morning!" She seemed to a bit confused as she said that until she felt herself comfortably laying next to Yasuo.

She instantly turned around and with a bright smile, "Onii-chan pet me!"

Instantly everyone but Yasuo narrowed their eyes as they focused on her.

"Sure," He said as he started patting her making her whine in satisfaction.

"Onii-chan, hug me!!" She said lifting her hands.

With a smile on his face, he hugged her then she laid comfortably on his chest, 'This should be the third one since she asked me to lift her back at the playground,'

Then Nanika manifests itself, it tinges Alluka's sclerae, irises, and mouth pitch black, causing the latter to appear larger.

She just looked at Yasuo with darkness overwhelming her face with no sound made in the room.

Though Yasuo looked at her with interest in his eyes as a purple bubble appeared surrounding her face. This is his Amplification domain as Yasuo sensed everything inside the bubble processing all of the information at a cellular level.

"It feels like there is a mask to more like there is another skin but with no cells, just darkness," Remarked Yasuo after observing for a while.

He looked at Nanika's face closely saying, "Well, you are cute, in your own bizarre way."

Then a weird smile surfaced on his face as he stated his wish, "Only I can make wishes and I can do so consecutively...."
