The girls were waiting for us in front of the tents with furious expressions. Hirata stood before them and tried to calm them down.

"Don't too stampede. I think we should talk about it first."

"It's okay, Hirata-Kun. This isn't about you though. " Sato said. I felt something different from usual in the girls' group. After considering it a bit, I got a conclusion.

Karuizawa who was a leader of girls wasn't there. So Sato and Shinohara acted like their leader instead.

"What happens?" Yukimura asked and yawned.

"Karuizawa-San's underwear was disappeared. " Shinohara said with anger.

"Yabai!" Yamauchi shouted. "We have to find it. Sorry, how is it look like?"

Sato sighed and said with embarrassment.

"It's a white panty."

"Is there some pattern on it? Please give me more detail. How is it smell? How is its surface?" Miyake stepped on Yamauchi's foot for being perverted without reading the atmosphere.

"However. Why do you look like us as we are the culprits?" Ike asked.

"Our package is outside of the tents. If someone wants to steal it, he can make it easy. So the culprit is among us here! I bet with my grandfather's name!" Onodera announced.

The boys looked at each other with panic. Yamauchi pointed at Ike and yelled.

"Oi, Kanji. Last night, didn't you go to the toilet? You used very long time!"

"I just peek at the girls' tent to find if some girls hug each other!"

"Really? Aren't you the culprit?"

"What the hell, man? I'm shiptrash! Not a pervert!"

We started blaming each other.

"Anyway, we can't live with the dirty underwear thief!" Shinohara said.

"Wait a minute, Satsuki. It's no need that it was stolen. Karuizawa maybe lost it by herself!" Ike protested.

Wait. Satsuki? Everyone looked at him. Shinohara's face turned red.

"Mo, I told you don't call me with my first name in front of other people!" She cried.

"S--Sorry. I forget---"

Ike scratched his head and tried to not look at Shinohara's eyes.

Of course, it made us jealous until we want to murder someone.

"Oi, on this island, there are many places to hide the betrayal's body. " Yamauchi whispered.

"Don't too rashly, Yamauchi. Throwing his body into the sea is more efficient." Miyake whispered too.

I tried to ignore the criminal planning and focused on the problem we met.

"Um. I don't want to think that there is a culprit among us. " Hirata said to the girls. Sato took the lead role since Shinohara was too shy to do that.

"I know it isn't you, Hirata-Kun. But we want to check the boys' bag."

The girls insist like that, and the boys insist that they won't let the girls mess with their bag too. But Hirata called us to talk alone.

"Hirata. The bags are our private space. I don't want someone to mess with my space. " Yukimura said.

"I understand you, Yukimura-Kun. But we need to think on the girl's side too. The bag is your private space and the underwear is Karuizawa-San's space. Am I right?"

When Hirata used his own word to convince him, Yukimura couldn't say anything.

"But there is no need to be the boys, right?" Yamauchi pointed out. "It can be the girl too!"

Karuizawa Kei was the girl's leader. But her way to act could bother someone and made them hate her. In that case, this underwear stealing could be bullying.

But I didn't think the thing would be like this, because---

"Do you think there is some girl who dares to mess with Karuizawa?" Miyake noted.

"Are you in the girl's side, Miyake?" Ike asked.

"No. I think neither we nor the girls will be a thief. Don't forget that there is a foreign among us."

"Mii-Chan? Hey, that's racist!"

"Not that foreign, idiot. I mean the foreign objects. That girl from class C----"

Every boy said in unison.

"

Yes. Ibuki Mio acted unobtrusive for four days. But we couldn't deny the fact that she was from class C.

But unexpectedly, Ike spoke out.

"It can't be Ibuki-San."

"Why?" Yamauchi raised his eyebrows.

"The tents have one door, right? Last night, when I peek at the girls' tent. I saw Ibuki-San was sleeping inside of the tents near Kushida-Chan. She is the farthest from the door. And Satsuki was nearest to the door. She is easy to wake up. So if Ibuki-San went outside of the tents, there was no way that Satsuki won't know."

He completely didn't realize how he called Shinohara.

Hirata nodded.

"It makes sense. Before you guys came out. I talked with the girls a little bit---"

He started explaining about the detail that I could conclude it like this:

4 August

19.00 p.m. The fish party started,

23.00 p.m. The fish party ended. Karuizawa went to the river to change her cloth. It was the last time she saw that underwear. Then, she put it into her bag.

23.30 a.m. Everyone went to sleep. No one came out until the morning.

23.45 a.m. Ike came out of the tent and peeked at the girls' tent.

5 August

05.30 Matsushita came out of the tent to go to the toilet. She came back five minutes later.

06.00 Everyone got up.

06.30 Karuizawa went to the river to bathe. When she looked at her bag, her underwear was gone.

Yukimura considered the timetable and shook his head.

"There is no chance to steal it between 23.00-23.30. Because there were many people sitting outside the tents. But after 23.30 a.m. There is only Ike and Matsushita who have a chance to steal her underwear." He analyzed.

Now, everyone turned their face of suspicion to Ike who denied immediately.

"I swear to the god! I'll never steal Karuizawa's panties! If I did, I beg heaven to kill me with thunder!!"

Suddenly, the thunder strikes the tree behind him. The sky roared.

Ike yelled and flinched. While the girls screamed with fear.

"S---S--See. " Ike stuttered. "I don't die yet. So it means that I'm not a culprit."

"So it's Matsushita?"

Yukimura asked and looked around. We shook our heads at the same time. There was no way that our Onee-San would steal her friend's underwear.

And I knew that she came out on 05.30 for hitting Koenji's head and made sure he would sleep for a whole day.

"However, I think we should let them see our bag to show our frank. I may sound like a simp who does whatever the girls tell him but this is the best way. " Hirata suggested.

Don't worry, Hirata. The real simp was here.

Therefore, although we were still displeased. We agreed with Hirata.

We grabbed our bag but before we walked to the girls. Ike sat down and opened his bag hurriedly.

Sudo noticed it so he asked.

"What happens, Kanji?" He said.

"N--Nothing."

Of course, after he acted like this. Only the fool would believe him. Yamauchi turned our back to Hirata and asked Ike again.

"Kanji. What's wrong?"

Ike might know that he couldn't hide the truth anymore. So he took the underwear out of his bag.

It was a girl's underwear. Pink and pinned the teddy bear in the middle.

Yamauchi opened his eyes wide. "K--Kanji. Are you---"

"I'm not a thief! I don't know how it appears in my bag."

Yamauchi looked at Ike with disbelieve. Different from me and Sudo. Sudo didn't mind whether his friend steal it or not in the first place. But I knew that Ike didn't steal.

"If you steal it, you should be panicking when they asked to check our bag. But you're not. More than that, there was no evidence that he steal too." I pointed out.

"Ayanokouji!!!!!" Ike cried.

"So what do we have to do?" Yamauchi said.

"The girls would be furious and didn't listen to anything if they found out that Ike has Karuizawa's panties. We should hide it."

"Oi. You guy over there hurry up!"

Onizuka called us. Ike flinched and crammed Karuizawa's panties to me immediately.

"Do you think so? Ok. Hide it."

"You son of a---" Before I finished my line. Yamauchi and Ike ran away. I looked around panicking while holding Karuizawa's panties in my hand just like the hot snack.

Before I realized it. I threw it into the forest and ran to the line for checking the bags.

After we finished the checking. The girls still didn't believe us so they insisted to check our tent too.

"Ah. I will check them. I will check them. " Sato raised her hand and ran into the tent that I slept in last night. She looked too happy for some reason.

After she came back. Her hair looked messier.

Ok. After we finished checking everything. I insisted to check Sato's bag too.

Although they checked our tents. The girls were still displeased.

"Ah. Hirata-Kun. It's possible that they hid it in their pocket. I saw Ayanokouji-Kun, Yamauchi-Kun, Sudo-Kun, and Ike-Kun speaking something to each other over there." Onodera said.

"Hey. There in no way to be Ayanokouji-Kun! He is religious!" Mori protected me.

"And there is no way to be Ike too!" Shinohara shouted.

"No. I don't think so. He just admitted he peek at us when we slept, remember?" Sato pointed out.

"He just wants to see us kiss or hug each other! He is a good man!"

"Excuse me. Shinohara-San. I don't think peeking at the girls at night and hoping to see they kiss or do weird stuff can be considered as a good man."

Since Shinohara, Mori, and Sato protected us. I and Ike don't need to be checked. So we just stood there, watching Hirata checking Sudo and Yamauchi.

His soft hand fondled around their body. Touching their chest, rubbing their thigh, grabbing their bottom. Hirata filed his face to their face. Looking at every space on their body. Whispering with a soft tone, "Nothing here".

Ah, I was jealous of them. I wanted to be touching like that too. I imagined he did that to me.

"Mo! Hirata-Kun! Don't be naughty! Don't touch that!" I mumbled. Ike glared at me with thrilling. "Oh, I mean---Oi, Hirata. How dare you touch that?"

Ike stepped farther from me. So I guessed the way I delivered the word wasn't the problem.

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

Hirata couldn't get anything from Sudo and Yamauchi. So the conflict was freezing for a while.

Around 10 a.m. Hirata summoned us again. When we all were together. We saw Karuizawa standing over there with red eyes. She looked furious.

"We can't trust the boy anymore! We can't live in the same space!"

"But if we separate from each other, it can cause the problem. More than that, the test was almost ended. We are friends. We should be together until the end."

"...It's true but I can't live in the same space with underwear thief!"

When Karuizawa who was a victim said that, Hirata couldn't do anything. Before we could protest, Sato stepped up and draw the line between us boys and girls.

"What are you doing?" Ike asked, raising his eyebrows.

"Matsushita-San. Read it." Sato said.

Matsushita Chiaki nodded and started reading something from her note.

"According to the conclusion from the general assembly of class D girls' meeting. We want to announce that behind this line is under our sovereignty. No man except the man that the general assembly approves can cross this line. If someone did, we would consider it as sovereignty and punish him without inquiry. In conclusion---" She looked at us and said with a soft tone.

"From now, we will separate. Don't cross this line."

Karuizawa Kim nodded.

"Except Hirata-Kun."

"Why does it have to be Hirata? He is the boy too. " Yukimura protested.

"Because Hirata-Kun is the only one we can trust now. And we need someone to help us." Karuizawa said.

It was the truth that Hirata Yousuke was the most reliable one. Not only for the girls but also for the boys' group. We cut Hirata from the suspect list automatically.

However, when it became honest discrimination like this. No one could stand.

"Huh. He might be the culprit though. " Yukimura mumbled.

"What? Ridiculous! Hirata can't be the thief!"

"You think he isn't because he is your boyfriend? Come on, Karuizawa-San. You are the one who is ridiculous."

If Shinohara joined this argument, it would be more bloody more than the battle of Sekigahara. But since she was sad about the fact that Ike couldn't cross the line to her anymore. We lost to the girls' stubbornness with not much injured.

At that moment, Horikita spoke out.

"I don't agree with you. Karuizawa-San."

Karuizawa glared at Horikita with scary sight.

"Pardon? Aren't you agree with us in the meeting, Horikita-San?"

"I agreed with you and I signed on that declaration. But I don't trust Hirata-Kun. Of course, he might be the most decent guy in this class. But you can't deny the opportunity that he can be the culprit."

"Huh. Hirata-Kun can't be the culprit at all."

"It's your personal opinion."

Karuizawa laughed and embraced. "You won't understand though. Someone like you never understands the nature of humans. You have no friend, don't you?"

"Oh! That's harsh!" The boys who became the audience shouted with excitement. The girl fight was always fun.

"I have no friend, but I have a brain."

"Ugh! Roasted!!" The boy yelled.

"Hm. It must be a little cute brain. Because you can't even use it to realize if someone is the good guy. " Karuizawa said.

"Aw! She just calls you stupid!"

"I don't mind if you call me stupid though. Because my father taught me, be mercy with the one who inferior." Horikita replied.

"Woh! That's wicked! Fight! Fight! Fight! Fight!"

Karuizawa and Horikita said at the same time. Then, they returned to confront each other.

"Karuizawa-San, The point is I don't agree that you allow Hirata-Kun to come into our space alone."

"So what do you want?"

"Allow another boy to cross to our space too. If there is Hirata and another one. They can invigilate each other."

"Ridiculous!"

The argument seemed to be more dangerous. Hirata might be thinking this is the best way to compromise so he stepped in.

"I agree with Horikita-San. I have to take care of those stuff on the boy side too. If there is someone to help me, it'll be great."

"...If Hirata-Kun said so... Fine. Who do you think we should allow him? Not Ike-Kun, Shinohara-San." She said without looking at Shinohara who seemed to be hopeful for a second. "And don't even think to volunteer, Yamauchi-Kun. Since Ike-Kun became shiptrash. You are the scariest one here. " She also said without looking at Yamauchi who almost raised his hand.

I wonder who would Horikita choose.

"Ayanokouji-Kun."

Oh, it was me. I see. I see.

"What?"

"Hehe." Karuizawa laughed. "So you choose your only friend. So ridiculous, Horikita-San. How can I trust this guy?" The way she delivered the word this guy made me know that she was still angry with me since that time.

It seemed like Karuizawa Kei was the vengeance person.

But without expectation.

"I think we can trust him," Sato said. "Right, Mori-San?"

Mori nodded in agreement. "Ayanokouji-Kun is the good guy."

"But Mori-San! Sato-San!" Karuizawa protested.

"Huh, that lucky bastard. " Ike shook his head. "I think he is the best choice though."

Most of them agreed with Horikita. I was the only man who can be on the same table with Hirata in the first place. This was the most reasonable.

Because of it, although she wasn't satisfied. Karuizawa didn't have any choice but to accept.

"Tch. If you want so. " She mumbled and walked back to her tents.

Horikita turned her face to me. She nodded to me.

Ah, Horikita. Do you do it for me? You confront the girl's leader because you want to be close to me? Well, maybe I could forget Ichinose this time---

But then I realized that why they need the man in their boundary----

"Move your ass here! And started moving these tents!"
