7th December

I went through the cabin and found myself walking on the 4th floor of the cruise where was the girls' rest.

I didn't know which room that Horikita was, but I just randomly knocked on a door.

After waiting for a while, the door was opened.

"Ayanokouji-Kun?" Horikita was on the door frame, she looked better than yesterday. She seemed to be surprised to find me standing in front of her room.

"I think I should explain something to you first. " I said.

"I'm about to call you anyway. " She nodded and said. "Talking in my room isn't good, what about we go talking at the lounge?"

"Good idea."

We agreed to each other. Therefore, we walked to the lounge on the rooftop of the cruise. When we reached there, the sky became orange. The view of the sparkle at the horizon was so beautiful. It reminded me of the scene at the special building.

We sat down and ordered the drink. While waiting for it, we started our conversation.

"I came to you first, because I knew that from now on, you will be surrounded by the classmate who admires you."

Horikita raised her eyebrows.

"Admire? Didn't I make the class lose 30 points? They should hate me."

I nodded. "You did. But you also give our class 372 points."

"" Horikita shouted, making the waitress that served us the drink flinched.

"Be quiet. Horikita. " I warned her.

"How can we do that!?"

"Um. Because we could guess about class A and class C's leader. And because of our domination on that territory. Of course, the disappearance of Shinohara and more, also your retirement, cause us to lose 40 points. But our class was still very high."

"But...what about Ibuki-San? Didn't she know our leader?"

Well, it was complicated.

I started explaining.

-------------------------------------------------------------------------------------------------------------------

After Horikita's retirement. We need someone to be our new leader.

Because of Horikita's dying massage (Horikita: I told you I didn't die yet!), I decided to take this role. We could change the leader if it was necessary.

"I see. Ibuki-San will guess me as a leader, But when you became the leader, class C will be wrong and lose 30 points." Hirata said.

"Really?" I tilted my head. I didn't think about that, I just thought the class couldn't win without the leader.

But if Hirata said so, I guess it was also Horikita's plan.

Because we could solve the case, our class became harmonious again. The Berlin wall was destroyed. Ike and Shinohara almost ran to each other, Yamauchi kicked Ike's ass before he could do. None of us complained about it though.

That night went easily.

When the noon of the 7th day came, our test was finished.

We packed our stuff and headed to the beach.

Class A and B were waiting for us at the beach. I didn't see any piece of class C.

Honami, Cho, and Ryuji waved to me, I greeted them back. Behind them, I saw Chihiro whose mouth was covered with the muzzle.

Katsuragi and Yahiko were there too, they nodded to me as greeted.

After waiting for a moment, Class C appeared----

-------------------------------------------------------------------------------------------------------------

"It must be Ibuki-San. " Horikita guess.

But I shook my head.

"It was Ryuen."

"Ryuen-Kun? I think he retired with his classmate."

"Well, he didn't. Actually, Kaneda who was with class B and Ibuki retire instead so Ryuen became the last person on the island." In Hirata's opinion, Kaneda was a spy too.

Horikita lowered her head and thought.

"He hid for sure, to make us think he retired from the test. And he also knows class B and class D's leaders. He will get 100 points! More than that, if he knows class A's too--"

I shook my head.

"I don't think he will guess Class A's leader."

I propagated my conversation with Ryuen to Horikita.

--------------------------------------------------------------------------------------------------------

When Ryuen saw us, he grinned and walked toward us.

"Kuku. How are you, Ayanokouji? Are you prepared to lose our battle?" He asked me.

"I can't remember that when I agree to a battle with you?" I replied.

Ryuen laughed.

"Try to hide your ability, Kuku?" He shrugged his shoulder. "There is no need though, you will lose anyway, Kuku."

"What do you mean?"

"Well, if we wrote your leader's name, you would lose 50 points, Kuku. " He grinned. "What about class A write your leader's name too?"

-----------------------------------------------------------------------------------------------------

"Katusaragi was Ryuen's ally?" Horikita said.

I shrugged my shoulder.

"I don't know. How do you think?"

"Um. Ryuen-Kun told us that there were only two people from class C running away from his camp. One is Ibuki-San, another is Kaneda-Kun. " Horikita analyzed. "There is a high chance. Because there is no spy in class A. This's bad. We will lose 100 points."

Then she realized.

"No, we didn't lose 100 points. In fact, they both lose 30 points!"

"80 points. " I fixed her words. "I wrote the right name."

"So you can guess class A and C's leader?"

I nodded.

"I used the whole night to find the evidence, My super-deduction analyzed the statistic, the evidence, the opportunity to conclude who is the leader."

"Really?"

"Of course, no. I just randomly choose their name."

I zipped my orange juice, it was very cold.

I felt the weird sight from Horikita.

"So you just write the first name that comes into your mind?"

"For class C that I guess Ryuen, yes. But no for class A. At first, I decided to choose Katsuragi. But I can't remember his first name. So I choose Totsuga Yahiko instead."

Horikita sighed. "It makes sense for some reason. Just like our class, if we choose Hirata-Kun or Karuizawa-San, there is a high chance that they can guess the name."

I got her points. The leader should be the responsible one and not that outstanding. I didn't know if Yahiko was the responsibility monster or something, but he was a kind of NPC that you couldn't remember his name and trustable enough for this kind of job. This made him was the perfect choice for his class.

Horikita didn't that outstanding compare to Hirata or Karuizawa.

But because of the result, if there was this kind of test again, I won't surprised if they would suspect Horikita most.

"So what about the result?"

"As I said. We got 372 points and win first place. Followed by Class B with 140 points, Class A with 120 points, and Class C without points."

When the result was announced, Ryuen opened his mouth wide. It was the most hilarious picture I ever saw.

Horikita started calculating the total class points immediately.

"Class A has 1140 points, Class B has 877 points, Class C still has 735 points, and Our class has 459. " She sighed. "We are still far from them."

"But closer, isn't it?" I said. "It's because of you."

"I didn't do anything. " Horikita shook her head.

"Come on, don't be shy. That's my role. You left me a dying message that told me to become a new leader, didn't you."

"First, I'm still alive so it can't be called a dying message. Second, I didn't leave anything to you."

"But you gave me a card."

"I just dropped it by chance!"

"Oh, so it didn't mean anything?"

"Yes!"

I see. I sighed and turned my glare to the sunset.

"It might be the coincidence then."

Horikita raised her eyebrows. "You still use that word?"

"The fate is the hilarious thing, Horikita."

Horikita looked at me with curiosity. At first, I thought she wouldn't believe me and started threatening me.

But what she did was nod.

"If you said so, I'll believe you."

"Hm? Weird. Normally, you won't believe me at all."

Horikita sighed.

"Actually, I still don't believe you. But you are my genius pervert sexually harasser who falls on the girl every 2 minutes and hides his ability. I believe that you have a good reason to hide it."

Horikita zipped her drink.

"The most important thing is you will give me a hand when I need it, that's all of it."

It was my delusion or her tone sounded softer.

"Can I say that you trust me?"

Horikita turned her sight to the sunset too and said without looking at me.

"Do what you want, Baka."

Ah, when was the last time I thought she was so cute?

At that moment, we heard something.

"Rokusuke-Kun! Drink the milk, please."

"No way! I want to drink the soda!"

"It isn't for a kid!"

We turned our eyes to the chaos and saw Koenji Rokusuke chased by Hirata.

Koenji smiled when he saw me. Then, he ran toward me and hid behind my back.

"Kiyotaka-OniiChan, help me! Yousuke-OniiChan force me to drink the milk!"

Horikita looked at me unbelievably. "Kiyotaka----OniiChan?"

Hirata reached us, he seemed to be so tired.

"Hi, Horikita-San. You are so great!---Rokusuke-Kun. Eating soda before dinner is bad!"

"But I want to! " Koenji cried. "I hate you, Yousuke-OniiChan!"

I sighed and rubbed Koenji's head.

"There, there. Rokusuke-Kun. Yousuke-OniiChan is right. Milk is good and if you drink milk, you will be taller!"

According to his height, he was the last one on earth that should drink more milk though.

"Taller? Tall is good?"

"Yes, tall is good. Everyone loves a tall guy! (Disclaimer: Ayanokouji's personal opinion.)"

Koenji's eyes were sparkle.

"I want everyone to love me! I will drink milk!"

"But, Rokusuke-Kun, if you want everyone to love you, why did you say you hate Yosuke-OniiChan? If you say you hate someone, they will hate you too. " I taught him.

Koenji nodded and looked at Hirata.

"Yosuke-OniiChan. Do you hate me?"

Hirata smiled softly. "I never hate you, Rokusuke-Kun."

"Uwa! I'm sorry I say I hate you! I love you, Yosuke-OniiChan!" Koenji cried and hugged Hirata. While Horikita looked at them with many feelings.

"What the hell happened on the island?" She mumbled.

"Well, it's complicated---"

------------------------------------------------------------------------------------------------------

Back to this morning.

Matsushita called me to the place where she hid Koenji's body. Koenji didn't wake up for 5 days. But he was still breathing.

Matsushita kneeled beside his body and considered him.

"The test ends today. How should we do?" I asked her.

"Um. I think the best way is to throw him into the sea. " Matsushita said. I flinched and shook my head menacingly.

"No way! I won't kill anyone!"

"You don't have to. Onee-San will do it, you just keep your mouth close."

"Are you insane? I don't want anyone to die either, also I don't want my classmate to be a murderer."

Matsushita smiled and titled her head.

"Aw. So sweet. This is the reason why I can't get my favorite little brother get into trouble because of this man."

"Last time I checked, my last name is Ayonokouji, not Matsushita."

She took the big log from the floor and swang like a bat.

"I will hit him to die before that, he won't suffer when I threw his body into the sea."

"Don't do that!"

I tried to stop her but then, Koenj's eyes were opened.

"Ah---Where am I?"

It triggered Matsushita. She raised her log, I see that and hold her hand immediately.

"Let me go, Ayanokouji-Kun. I will kill him before he will expose our crime."

"Your crime. Well, our crime. But you can't kill him!"

Koenji who made his eyes big looked at us interested.

"Onii-Chan and Onee-Chan are fighting?"

We bogged down and looked at him.

"Pardon. " I said. "What did you call me?"

"Onii-Chan!" Koenji said happily. "Ah, where are we? It looked like a forest I saw in the photo book!"

Matsushita and I looked at each other.

"Is he---amnesia?"

"Possible."

It wasn't that surprising. We hit his head again and again. Well, it was still surprising, since we hit his head many times, I expected more harshly injury like hemorrhage.

"Do you remember your name?" Matsushita asked Koenji.

He nodded. "Koenji Rokusuke, 6 years old!"

"Shit. " Matsushita exclaimed. "Amnesia."

"What do you mean Amnesia?" Hirata spoke out.

"Well, we hit---Argh!!!!!" I and Matsushita screamed and turned around.

Hirata was there with the whole class, looking at us with confusion.

"H--Hirata-Kun. How long do you stay there?" Matsushita stuttered.

"Just a moment. What happened with Koenji-Kun?" The class representative said with worried.

I sweat. And looked to Matsushita for help. But she seemed to be panicking too.

Ah, is this the end?

I would be fired and sent back to the white room. Became that man's tool again.

Maybe, confession was the best way.

"Coconut---"

"This morning, the coconut fell on his head. " Matsushita spoke out. "I and Ayanokouji-Kun found him laying down on the floor. When he get up, he became amnesia."

Hirata opened his eyes wide. "Really, Ayanokouji-Kun?"

No. I almost answered that, but Matsushita looked at me with the sight that said. "Ototo better know how to make Onee-Chan happy.

"Yes. " I nodded. "He became a Shota because of the coconut, we didn't commit the crime or plan to kill him at all."

"Coconut?" Koenji titled his head. "I know it, I know it. I love coconut, it's sweet and delicious!"

He looked around at our classmates.

Then, he smiled and pointed at Sakura.

"Coconuts!"

And Hasebe.

"Coconuts!"

And Kushida.

"There are coconuts everywhere!"

Then, Mii-Chan.

"Coco----" He stopped and shook his head. "No, it is a surfboard!"

No need to be a sleeping Nene. After comparing those four differences, we all could decode them.

We tried to hold our laugh. Mii-Chan's eyes became blank. The Chinese loli turned her face to Hirata.

"Hirata-Kun. " She said coldly. "Please tell the teacher that from now on, our class has 39 people."

"W--Where is another one?" Hirata stuttered since he tried not to laugh.

"Well, let's say. He wants to take a rest on this paradise island for a long, long time."

---------------------------------------------------------------------------------------------

"This is the reason why we have to babysit the 6-year-old Shota in a muscular man's body."

Horikita blinked her eyes and looked at Rokusuke-Kun.

"Oh, I forget to introduce you. Rokusuke-Kun. This is Horikita Suzune."

Koenji-Kun bowed to Horikita.

"Nice to meet you, Horikita-OneeChan! I'm Koenji Rokusuke, 6 years old!"

"N--Nice to meet you. " Horikita mumbled.

"You are so cute! Can I call you Suzune-Onee-chan?"

"Yes...I guess."

She blushed a bit.

"Ok, Rokusuke-Kun. Let's take milk! And after you drink it, we can go to do something fun!" Hirata said while rubbing Koenji's head. "What do you want to do?"

"I don't know, Yosuke-OniiChan. Haruki-OniiChan tell me to bathe with the girl! He also gives me a camera!"

Ok, we needed to protect this kid from Yamauchi at all costs.

"Ah, I think you are too young for that kind of stuff. You need to grow up, then, you can pay for bathing with a girl or girls!" Sometimes, Hirata looked surprisingly professional. "Now, what about swimming? Can you swim?"

Koenji shook his head.

"Well, I will teach you! Let's go!"

"Um. Wakata!" Koenji seemed to be happy.

"Well, see you. Horikita-San. Ayanokouji-Kun. " Hirata nodded to us.

"Goodbye, Suzune-Onee-Chan, Kiyotaka-Onee-Chan!"

Hirata hold Koenji's hand and walked out of the lounge, leaving I and Horikita alone.

Horikita sighed and looked at the sunset.

"Well," She said. "At first, I think I'm more special than everyone in this class. Now, I learned that I'm pretty normal compared to my classmate. And it's good."

I didn't want to interrupt her. But if the compass fighter who could use the demon blood art and will become the predator every time smelling the waffles was pretty normal. Yamai Ren would be a pretty kind girl.

------------------------------------------------------------------------------------------------------

After a little dinner with Horikita to ceremony our success, I walked to the rooftop.

The sky was dark and calm. The sky and sea became one.

Behind me, it was a colorful light from the lounge. Everyone was gleeful with the luxury of this cruise and the easiness that they didn't meet for a week.

But there was someone who never met the easiness for a long time.

These kinds of people were used to the uneasiness and were more comfortable when they were a problem in their mind.

Someone like me and a girl who was on the rooftop too.

"Good evening. "

I greeted her, she turned her face at me with surprise.

"Oh, good evening. Ayanokouji-Kun."

"I didn't expect to find you here, Inogashira. " I called her name. "Or should I call you the detective Kokoro?"

Inoghira Kokoro opened her eyes wide.

"Don't deny. I know it was you who solve the case. You are the real sleeping Nene. You made Mori unconscious and act like her to close the case."

The girl pursed her lips. She became silent for a few minutes, before nodding as giving up.

"How do you know?"

"Come on. You hid behind the tree that Mori lend on, How can no one see you?"

But it came out that there was only me who saw her.

Inogashira sighed.

"You are right. Ayanokouji-Kun. I used Mori-San as my puppet. If you don't know, I have a talent at investigation and changing the voice." She twitched her face a bit before speaking with my voice. "Hello, I'm Ayanokouji Kiyoyaka. I really enjoy Buddhism."

It was very impressive. There was no difference from the real one.

That was why she could sing like Luciano Pavarotti. She could change her voice.

"Why do you have to hide your talent?" I asked her.

"As you see. I'm very shy. Every time I tried to explain my deduction to anyone, I can't say it out loud. So I need to use someone as my puppets." Inogashira said sadly. "More than that, I have to hide from something."

"Something?" I raised my eyebrows.

She nodded.

"Actually, I'm not a 15-year-old girl as you see. I'm older than this. Before I enrolled in this school. I was the high schooler detective. One day, I went to investigate at the amusement park. I saw a secret organization planning a crime. They noticed me and catch me. They forced me to take the weird medicine and make my body younger."

"Wait. What is your real age?"

"Sixteen. " Inogashira said. "Despite my body is fifteen, but my brain is sixteen. My name is the great detective Kokoro!"

I heard the saxophone sound again.

"This organization is the thing that I tried to hide from."

"Do you know its name?" I asked her.

"I don't sure. But I called it the black organization." Inogashira sat down on the floor and looked at the sky.
