The Second Dimensional Shuttle of Problem Children

Izayoi, Toyama, and Aria took a taxi to the Yokohama Landmark Tower, which is not far from Yokohama Station.

Riko's hiding place is in this commercial building called Minato Mirai 21 Core.

In order to return the cross, we asked her the exact location - she said it is now on the roof.

Well, this is also a trade of stolen goods. It is normal to choose a place where no one will notice.

The humid sea breeze blew strongly on the roof of the Landmark Tower.

According to the introduction in the elevator lobby on the first floor, the height here is 296 meters. It is the tallest super-high-rise skyscraper in Japan.

Maybe it's a psychological effect, the fast-moving dark clouds in the sky also make people feel so close.

This is a rooftop that is prohibited for unauthorized entry. Of course, there is no one in sight - we walked onto the helicopter platform, and there were only four corners with slightly different heights around us, and there was no protective net.

「Xiao Jin——！」

Ta-ta-ta-ta!

Riko, wearing her transformation uniform, ran over, her honey-colored hair flying in the wind.

「Xiao Jin and Aria are really a good team! They can do something that Riko can't do so easily! I am so shocked and admire them!」

「Kinci. Give her the cross quickly. I get angry when I see her happy.」

「Oh, Arian, are you jealous that I took Xiao Qi away from you? I understand." Riko shouted with joy when she saw the cross.

As fast as a magic trick, she put the cross through the thin chain around her neck.

「Oh, it's a nice view, but she's wearing a skirt. And it's a light and frilled skirt.

The fan dances in front of my eyes, and I can't help but look over there."

Izayoi commented as he looked at Riko.

「"Riko. I'm glad to be here first, but you have to keep your promise, okay?"

Aria crossed her arms and warned her with her temples pounding.

Ah, she looks really angry.

Riko,

「Aria really doesn't understand Riko.」

「I will thank you very much. Come, please untie the bow on the gift."

What...? Does it mean that if you untie this, the contract will be...completed?

I am fed up with Riko's inexplicable behavior.

I untied Riko's bow.

「Oh, by the way, this is the reward for helping me this time."

Riko said and kissed Izayoi.

「I helped, but I didn't expect this kind of reward."

Izayoi said to Riko

「Of course, Izayoi's help was a big help, so this kind of reward is fine.」

「Yeah?」

「You, you, you, you, what are you doing!」

「What? Isn't it just a kiss?"

Izayoi answered.

Then he looked at Aria next to him, whose face seemed to be petrified by the blow just now.

「Aria"

Ha.

Aria finally recovered from his petrified state, his face flushed and his fangs bared.

「Uh, well... I've been feeling that this is going to happen! It seems that wearing a bulletproof uniform is the right thing to do for the sake of caution. Kinji, let's fight. Pay attention to cooperate with me」

——As you order

「Then won't Izayoi-san participate?」

「Your feud has nothing to do with me!!」

「That's true."

Riko turned to Aria and the others.

「I'll draw my gun first, Holmes - this is Butei High School, it will be easier for you to do it this way, right?"

Riko pulled out two famous guns from her skirt, the Walter P99, from both sides.

「Heh, isn't this caring? This way we are acting in self-defense."

Just like a mirror image, Aria also pulled out the black and silver M1911 that didn't match the small hand.

「Before I make a hole for you, there is something I want you to tell me, Riko. Why do you want that kind of thing? I think... it shouldn't just be because it's a relic of my mother, right?"

Aria said, pointing the gun at the cross on Riko's chest.

Riko... put Walter close to her mouth and laughed.

「——Aria. Have you ever been called a"breeding bitch"?」

「Breeding bitch……？」

「Is there a dog that is fed with rotten meat and muddy water and lives in a small cage? Think about it. Aren't there often news reports about vicious pet dealers who put dogs in cages and abuse them in order to breed popular dog breeds? That's it, that. It's the human version of that."Imagine it,"

Riko said with an exaggerated smile.

Under the dark clouds that flowed like fast forward, a strange atmosphere filled the roof of the landmark tower.

「You, what do you mean?……！？」

「You who live in ordinary society may not know that this is how Riko got here."

Izayoi answered the question directly.

「What did you say?"

Before Aria could finish her words, she heard Riko say

「What a joke! Am I just a gene? Am I just the number '4'? I'm not! No, no, no! I'm Mine Riko Robin the 4th! Not a machine that exists to give birth to the '5th'!"

Riko was halfway through her sentence...she looked up at the sky and yelled at someone who was not Aria.

That language could not be called a conversation with what Aria said.

It was incomplete and the meaning was not coherent at all.

It made people feel that Riko was just letting her emotions run wild.

Crack! Boom boom...

From the other side of the sea, faint thunder was heard in the distance, and Aria shrank back.

「……You asked me"Why do I want to do that kind of thing", Aria."

Riko glared at Aria and smiled.

「This cross is not an ordinary cross. This is the cross that Riko's mother, her favorite mother, gave to me before she died, saying,"This is a treasure that can rival all the wealth of the Robin family." So even when Riko was locked in a cage, she kept it in her mind, thinking that this was the only thing that must not be taken away by others... and kept it hidden in her mouth. And——」

「Olmes Toyama Kinji, you two, become my stepping stones!"

Pa la——————

A sound like a small lightning sounded.

Riko, whose cute face suddenly froze, only half...slowly, turned her head.

And,

「……Why...why would you……」

As she said that, she fell to her knees.

Riko's small body fell forward like that, revealing the man standing behind her.

「Teacher Xiao Yeming——！？」

Aria just called out that name

「That guy is actually Iyou's No. 2 Vidora, Aria"

Izayoi reminded him
