When Akatsuki was playing around Haruka's body, to teach her that he's not that such dignified person as Haruka thought, there was someone called him by phone.
At first Akatsuki said jokingly like "Is this new `it's me` conning?" to Chikage that picked the phone for him, he immediately knew that person after talking in the phone.
Her name was Arashinomiya
She told Akatsuki that she would come to that island in three days.

Akatsuki and the girls came to hotel where Arashinomiya was.
When the girls knew that Arashinomiya was in highest floor of that hotel, they immediately understood that was royal suite, which the price for each night easily surpass 2 million yen.
Listy and Miyu too understood she was the person that Akatsuki talking in before (in vol. 6 when they enquired where Akatsuki got money for their living cost, he said there was once he won the bet against some woman and the prize of it should enough for them to accommodate their living cost).
Just before came to that floor, Miyu wanted to go to toilet, Listy and Kuzuha then accompanied her. Between the girls, individual activity should avoided when outside the home.
Miyu, Listy and Kuzuha met some granny in wheelchair with young girl who pushes that wheelchair.
Those three thought, maybe that granny was Arashinomiya because the impressing aura those two gave out.
3
As soon Miyu finished her thing, just outside the women toilet there were several men in uniform wanted to attack them but the girls swiftly suppressed them easily. The girls thought those men could actually targeting Arashinomiya.
They called the staff and ask him to handle those unconscious guys.

In the royal suite room, there were the granny and young girl that Miyu saw them before.
The young girl walked to front of Miyu and grabbed her breast, she didn't stop until Akatsuki said "That breast is mine, stop it already granny" to the young girl who wear kimono
6
That young girl was actually Arashinomiya Yoshiko instead of that granny in wheelchair, (嵐ノ宮貴子, 嵐ノ宮 this part Arashinomiya is obvious, but I don't know how to read 貴子 as name, the second part reading it as "ko", but the first kanji is usually what you find in 貴方 (anata) and 貴殿 (kiden, an archaic way to address second person), it could be, Ako, Kyoko, Yoshiko, Takako, hmm)
This Arashinomiya was the person who has many companies (incorporation) and could be said the one who controlling economy from the shadow.
She was in artificial body, known as cyborg (not made from metal of course
) purely the product of scientific research.
She too had many scientific/medical laboratories and that artificial body was one product from one of laboratories.
But since the body wasn't absolutely completed, the granny body was there to improve the nervous signals work. When Arashinomiya cut it completely, the granny was as if the doll cut from the string.
7-9
This part where Akatsuki and Arashinomiya debating about Akatsuki's action defeating one of COCOON also the future plan for this island.
Just like 4 country conference in Alleyzard, Akatsuki wonderfully handled this too with the end result was Arashinomiya's assistance for the island such as companies, expertise, politics and moving the essential resources to support the artificial island.
10
But Arashinomiya then gave some condition to secure her cooperation, she would cooperate if the girls (Miyu and others) passed her test.
Akatsuki immediately protested with loud voice but Miyu and others weere able to convince Akatsuki to let them taking Arashinomiya's test.
Haruka added with question to Kurono Ai (黒野亜衣), (don't you think Kurono would be cool to write it as Chrono?
) the Japan branch president of Albazen Optical company.
Ai said, since Haruka speficically asked it to her, so Haruka knew the hidden business of her company.
Haruka explained, Albazen was the rival company for magical tools maker that supplying for JPN Babel so Haruka knew that. Also the cooperation of Albazen should be crucial for the future fight against COCOON.
Akatsuki gave up with hard feeling, and before he went outside the room, he told the girls to not do excessive and just take it easily.
11
After Akatsuki and Ai went outside, Arashinomiya said to the girls that she didn't like them.
She honestly felt their existence purely a hindrance to Akatsuki, especially in the Kyouya's case. She intuitively knew that Akatsuki had to make that blatant fight because of the girls.
So she said to them to die, because even if they're taking some distance from Akatsuki, they still could be kidnapped and gave Akatsuki more trouble.
Shen said to them, even to this day, Akatsuki never let his guard down, and what he said about "new way to `it's me` conning?" also the tactic that made Arashinomiya let her guard down.
In contrast to Akatsuki, the girls didn't seem to be prepared enough. She took off some small container within her sleeve and said the bottle contained with some virus developed from her laboratories, only she could provide the vaccine, so it was proved that the girls let their guard down.
Miyu asked for some chance so Arashinomiya was to give them the test.
The test was, she told they should choose one among them who would be the most hindrance to Akatsuki in the future and kill her.
Arashinomiya gave them 3 hours to decide.
12
Akatsuki was in rooftop together with Ai (Kurono Ai) with her explaining about Albazen company.
Albazen company worked as magical tools maker which exclusively using ability from this world.
The existed magic in Akatsuki's world was very small compared to magic that used by people who come back from alternative world, but didn't mean it didn't exist.
Ai explained that her glasses was magical tool too. She challenged Akatsuki to touch any part of her body. But when Akatsuki wanted to touch her, he just couldn't touch her.
Ai said that the ability she has by using her glasses was to manipulate distance between things. She manipulate her body and Akatsuki's hand so Akatsuki didn't able to touch her.
Akatsuki impressed with it and asked that Albazen cooperation should already sure even without Arashinomiya's test to the girls.
In exchange, Ai asked to Akatsuki to give her some information about someone, she gave photograph of her together with other girls.
"I want you to give me some information about this girl, Mikagami Memeko (深鏡めめこ) who a member of Scarlet Dusk since two years ago. She's previous user of this glasses."
13
One of maid came to inform that the result of test would be after 3 hours. That maid, Sayaka, asked whether Akatsuki wanted to give all maids the thing he did before to all of them. She said they were excited when know they're going to meet Akatsuki again.
But Akatsuki had to refuse it by saying there's something that he needed to do for awhile.
When Ai enquired him what business that he need to do by refusing a beautiful maid, Akatsuki said he must to settle a thing
14
Within some area where many apartments for JPN Babel students, Kaidou was talking in his phone with someone
"You see Memecchi, don't you think that poor for me for such task? I meant, hey, I know I just have to observe him but sometimes he ordered me to do things."
"It's actually poor for me to listen your whining about your homo lover for awhile."
"Aww, I totally normal guy, if I must have a lover, it should a cute girl like you Memeko."
Immediately Memeko cut the line, several second Kaidou called her again and talking various thing (I inserted that conversation above because it's funny, also that joke would be a continue in next part, also it's not about "lover" but "ordered around by"
)
This part ended with Kaidou's phone ringing, and he said "Ooh, the rumored person now talking"
(This part Kaidou knew Memeko's background from Albazen and said the president of Japan branch came to visit Akatsuki, of course he knew about Arashinomiya too)
15-16
This part is discussion within Miyu and others about how to solve the test, I leave it out because nothing interesting in there
17
Akatsuki treated Kaidou a ramen. Kaidou said to Akatsuki that it's just rare Akatsuki to invite him. Akatsuki said usually he ate with the girls so he didn't have any chance to eat with some guy friend. Especially the guy who at least equivalently powerful as him.
Kaidou said "Don't say that everything I've done is paid with ramen." with Akatsuki "of course not, I just want to talk about something with you".
Akatsuki said to Kaidou to sit in rear sit of Sleipnir but Kaidou said with as if shocked "Akki ―― you sure aren't homo right?" with Akatsuki replied "Hahaha, stop joking or I'll run you over" (this continuation joke from before
)
In short, Akatsuki wanted to talk something but not in that current place, that's why he brought Sleipnir with him.
While riding too, Akatsuki asked something to Kaidou about Memeko, but Kaidou said he didn't know where she's now
18-20
The place where Akatsuki wanted to talk was the place where he and Kaidou fought at that night.
Akatsuki said he needed to finish what they started. The last fight was ended with some intervention.
Kaidou said jokingly that Akatsuki already finished Kyouya who got higher dimensional being ability, so isn't it obvious already.
Akatsuki said that defeating Kyouya didn't necessarily mean able to win against Kaidou, especially when Kaidou wasn't necessarily weaker than Kyouya.
Akatsuki said, if he won against Kaidou, he wanted Kaidou to quit Scarlet Dusk and worked together with him.
Kaidou didn't immediately refuse, asking what's in for him if he do that. Akatsuki said Kaidou would freely observe him from behind without conspicuously stand out.
That way Kaidou could fight with his heart content without anyone know, contrasted with what Akatsuki did for defeating Kyouya.
Also Akatsuki said Kaidou should feel itchy to settle their fight from before, that's why even though Kaidou didn't necessarily to observe him anymore but Kaidou still didn't leave from this island.
After Kaidou was consent with Akatsuki's reasoning, the next moment where those two fought by entering their respective zone.
21-22
The result of test, the position was changed, this time those girls that threatened Arashinomiya, and by doing that Arashinomiya should have no other choice except helping Akatsuki.
Immediately the test ended with the girls won, Akatsuki came with body full of wounds, he said he settled thing with Kaidou, so the other understood it, because they knew Kaidou at very least was on par with Akatsuki.
When Akatsuki was enquired about the result, he didn't answer and just said with laugh, the result of fight between them was only for them so Miyu didn't ask it more.
Akatsuki asked to challenge Ai once more, this time he was able to grope Ai's breast. Akatsuki explained even though the tool was very good, but it depended on user too, since Akatsuki moved his hand so fast, Ai couldn't be able to discern it so that's why Ai's ability didn't work on Akatsuki (he explained thing while groping Ai's breast, well, it's Akatsuki's usual signature
)
