Rose already felt the presence of hisoka, understanding it, Hisoka revealed himself.

"Oh my~, isn't it the undefeated rose~?"

Rose sighed, she already know where this is going.

"So, you want to fight me?"

Hisoka was surprised, nonetheless, his gut is telling him he knows her. He smiled creepily and said "well~, it seems you already know me~"

Rose removed her disguise revealing Akane making hisoka realize how she knows him.

"Oh~, I never thought you would create a hatsu to disguise"

"It's just for fun, anyway have you seen Gon and killua?" Akane got straight to the point, she can kill hisoka if he annoys her but he is required...for now.

"No, but I know they will come here"

"Even I know that. Anyway, if you excuse m-"

Hisoka attacked her not letting her complete the sentence. However, the attack didn't reach her. When Hisoka's punch landed near Akane's face, it immediately got reflected turning his fist into a bloody pulp.

Hisoka didn't know what happened, he went into a state of shock even if it is for a split second.

Akane smirked " oh hisoka~, I'm completely out of your league but since I need you for my plans, I will forgive you. Here, I will even heal you"

Akane used reversed cursed technique on Hisoka. he is needed for Gon's development. She also plans to devour Gon when he makes the contract with Nen for maxed out physical stats and aura. Even if it is inferior to post-rose Meruem, a 'little' power is still power.

Hisoka is surprised to see his hand get regenerated and thought 'a support type hatsu and a counter type hatsu? And what more surprises is she hiding?'

" don't worry, I won't kill you. Not exactly, I don't have any reason to kill you unless you give me one"

...

At the base of kukuroo mountain, a car arrived. From the car, a beautiful woman stepped out.

"That costs a total of 20,000 jenni miss"

Akane smiled "here"

The driver immediately left. Akane continued her travel to the top of the mountain. 

She already reached the 200th floor. She decided to spend some time in heaven's arena to increase her physical strength, stamina and endurance. They are already off the charts due to rabbit quirk but once she gained aura nodes, it received a boost. So, she spent her physical training in the heavens arena for three months. She even saw Gon and killua but she didn't interact with them.

Akane stood in front of the testing gates of the zoldyk mansion.

Guard "Do you need something, miss?"

Akane " Yes, I would like to know if Illumi is here or is he on a mission?"

Guard "Master Illumi is here"

Akane" Very well"

Akane directly went to the testing gates and pushed all the seven gates. With her current strength, she can lift 4,000 tonnes easily, pushing some 100 tonnes isn't even a task for her.

The guard didn't stop her, his instincts are screaming danger when she is near.

The butler didn't stop her either, They already got informed that she opened all 7 gates and is powerful. When she reached inner area of mansion, Gotoh escorted her to main mansion.

"I presume, you are here for master illumi "

"Yep"

In the main hall of zoldyk mansion, we can see some major figures of zoldyk family including Illumi, Silva, maha, zeno, kikyo.

Akane "It seems the whole party is here"

Silva " I heard about you from Illumi. For what exactly do you need my son?"

Akane " You can say I like him very much. I admire your family's work philosophy so, I plan to give you something in return for taking Illumi with me for... maybe 2 years? I will get bored of him very soon anyway, don't worry, I will return him alive and perfect~."

Zeno "I understand your intention, What do you want to pay us with young lady?"

Akane " It's for you to decide, do you want money? Protection? future knowledge? or control over the calamity from dark continent you are containing? Anything is possible. I can even extend your lifespans if you wish. Of course, some things require some human sacrifices but I'm sure you got the gist of it"

The whole zoldyk family remained silent. They were not surprised by her knowing about Nanika. Her tremendous aura is really something that can make anything possible.

Silva " We would like to discuss this personally"

Akane "Go ahead, I will wait outside"

When she left, Silva directly looked at illumi

Silva "Illumi, are you hiding something from us? Are you sure you don't know anything else about her?"

Illumi " She is overwhelmingly strong, I never saw her use her aura even when facing reasonably strong opponents in heaven's arena apart from using her transformation hatsu. That is the only information I have on her. Oh and she is sadistic and sensed me all the time"

The room remained silent once more.

Zeno "I propose we trade illumi for knowledge over the future"

Kikyo "Isn't control over 'something' more important?"

Silva "No, what father says sounds reasonable. The control won't last long even if she could do it."

Kikyo "That's right.."

After some more discussion. Akane is once again in meeting with the zoldyks.

Silva "We want Future knowledge but how far can you show exactly?"

Akane "The range is unlimited. I recommend the point when killua and that child leave this mansion forever which happens in very near future. Of course, I will show you how it happens and you will even learn some interesting things about 'something'  and killua from it"

Silva "I accept the trade"

Akane "Do you have any television in your mansion. Even computer screen should do the trick"

Kikyo " I know the place"

They went to milluki's room. Where Akane showed the future with her 'clairvoyant' technique.

Akane doesn't have any future sight ability. She is just showing them her memories with her cursed technique. She just manipulated them making them see what she wanted them to see.

Even if they selected control over 'something', she can easily do it with geass, cursed technique or her new hatsu.

She started showing them from when killua entered the mansion to reaching the hunters association hospital.

The zoldyk family learnt a lot from this confrontation.

Before leaving with illumi she gave them a warning

"This happens 1 and 1/2 years from now, just don't interfere with killua up until that point. By that time, he will grow incredibly powerful and explores his potential in Nen and I'm sure you realized his power. When he returns next time, you can do whatever you want"

...

In a hotel room somewhere in an abandoned forest near York new.

Illumi "what do you want to do with me from now on?"

Akane gave him a sadistic smile as a red chain manifested in her hand while a collar connecting to the chain manifested around illumi's neck.

"I'm going to enjoy torturing you for the next two years~"

She caressed his cheek " Don't worry, baby~, I will not let you die no matter what~ I just love you that much~. Maybe you are the only male that attracted me, so I will shower you with my love by torturing the soul out of you~"

Akane started using her construction cursed technique as the empty room began to get filled with 'toys' as Akane would like to call them with a red bed in the middle.

She chained him down to bed, covered his eyes with a blindfold and gagged his mouth. Dominatrix's clothes began to manifest over her as she whispered in illumi's ears in a sickeningly sweet tone.

"Call me master from now on, my pet~"

Akane is not really torturing him, she is just 'showing' her love and admiration towards illumi in a different way. She can't have sex with him like she did with females as she is a lesbian but love doesn't need to be shown only through sex.

For the next two years, Akane tried all the toys she has, 'showering illumi with her love'. She occasionally invited menchi to this place to relieve herself sexually. As for the job as a hunter, she doesn't give a sh*t about it.
