Chapter 29

Nagisa POV

This is seriously bad...

Nakamura-san noticed something strange of the headline in today's newspaper. So she decided to bring it to school and read it together with the whole class before jumping conclusion. The content of the following article goes like this.

An underwear thief specialising in targeting large-breasted women. The culprit is a large man, with yellow head. 'Nurufufufu' is his signature laugh. The culprit leaves behind a mysterious goo at the scene of the crime. The number of victims have increased from twenty to 24 last night.

As soon as Nakamura-san finishes reading aloud the article, the door slides open. Koro-sensei enters the classroom. What perfect timing. Almost everyone have a disgusted look on their faces. Even Karma-kun is frowning. The only one whose expression remains the same is Oichi-san. Koro-sensei looked at us in confusion. Nakamura-san wordlessly handed the newspaper to Koro-sensei. He grow paler by the seconds as he read on.

"This is totally you, Koro-sensei," Mimura-san said. "Honestly, I'm disappointed."

"How could you do this?" Okano-san adds.

"P-Please wait a minute! Sensei doesn't know anything about this!" Koro-sensei refute in panicking tone.

"Then what's your alibi?" Hayami-san asks, grabbing everyone's attention. "Late last night, when this incident occurred, where were you and what were you doing?"

Koro-sensei calms down in an instant. "Well... I was shaking around some french fries while moving up and down between the heights of 10,000 M - 30,000 M."

"WHO THE HELL COULD CONFIRM THAT?!" Almost everyone shouts collectively.

Yoshida-kun narrowed his eyes in suspicion. "There's no point in having an alibi in the first place."

"No matter where he is, for the most part, he can return to town in an instant," Hazama-san agrees with him.

Koro-sensei's face went pale again. Isogai-kun, ever the kind ikemen, jump to defend him. "Hold on, guys! We can't just accuse him like that! It's true that Koro-sensei has a lot of little worldly desires. But, if you think about all the things he's done until now, the worst he's done is... Picking up and reading porn magazines... Being bribed by photos of girls in swimsuits... Staring at gravure magazine during break like he's lost it and... He write out requests such as 'Hand bras won't do. Please let me give you a tentacle bra,' on postcards... And..." Isogai-kun pauses for a moment before lowering his head. "Sensei, please tell us the truth."

"N-Not you too, Isogai-kun!" Koro-sensei cries out, tentacles flailing. "Sensei is innocent! The nerve! All right, everyone come to Sensei's desk in the teacher office!" Koro-sensei slides the door open. "In order to prove the strength of Sensei's mind, I will throw away all the gravure magazines in my desk this instant!" Everyone exchanged uneasy glances before we move out the classroom. We follow Koro-sensei to the teachers office. Koro-sensei opens his drawer. Even from this distance, we can spot the large breasted women on the cover. "Look! I will remove all the contents of my desk-" He pulled out his magazines. Geez, there are at least half a hundred in there! And then...

Koro-sensei pulls out a pair of bras.

"Seriously?" Terasaka-kun stares at him incredulously.

"Hey, you guys!" Okano-san grabbed our attention. In her hand she holds the class roll book. "The letters written next to the girls... All our cup sizes have been looked into..."

A - Okano Hinata

A - Okuda Manami

C - Kataoka Megu

Forever O - Kayano Kaede

B - Kanzaki Yukiko

B - Kurahashi Hinano

D - Nakamura Rio

A - Hazama Kirara

D - Hara Sumire

C - Hayami Rinka

B - Fuwa Yuzuki

C - Oichi Chika

Kayano-san shrieked in rage at the entry, mostly because 'Forever O' is written. Okuda-san have to hold her in place. The girls cringed while the boys shifted uncomfortably. Okajima-kun is trying really hard not to show his excitement over the newfound facts of the girls' cup sizes. The only who remains unaffected is Oichi-san. Maehara-san flip over the pages. He let out a gasp and proceed to tell us that there is another list on the last page. It is a list of people in Kunugigaoka city with F cup and higher.

Koro-sensei splutters under the dirty looks everyone is giving him. "I-I know! Let's all have a barbecue right now!" He pulls out a cooler box out of nowhere. "I thought we'd have one after school and prepared these! Now, take a look at these skewers!" He pulls out three skewers... Piercing through three bras... The atmosphere soured even more. Koro-sensei start to hyperventilate. I can't believe. Did Koro-sensei really... To all those poor women... Would he really stood that low? Our Koro-sensei...?

Everyone hold their breath when Oichi-san take a step forward. Koro-sensei stops hyperventilating to look at her curiously. She gently take the skewers from Koro-sensei's tentacle, pulling off the bras. I looked at her curiously. What is she doing? Next she pull out more skewers from the cooler (again, there's bras on them.) Oichi-san took them all off and put them on the table. What is she doing exactly?

"Last night, someone stole my sister's underwear," She says. Koro-sensei grow still. "She told me that the culprit have a big, yellow head with big teeth." Big yellow head? That's Koro-sensei! "I tried to give you a benefit of a doubt, Sensei. I really did. But I can't do that anymore." Then her next words are filled with so much emotions.

"All of these bras belongs to my big sister."

Oichi-san pull out an Anti Sensei knife. Something changed in the air. I could feel it. Pretty sure the others can feel it too. I recognise this. This sensation... This is... Koro-sensei froze in fear and shock.

This is blood lust

And not the good kind. This is the exact same bloodlust I had for Takaoka-sensei back then. The kind that you should not have. Her blank expression might've fooled us but there is no mistake. Oichi-san is really pissed off. The aura she's giving off right now is very dangerous. It's palpable. Yet none of us make a move, all eager to see how this will play out (and out of fear). It felt like someone flipped a switch on Oichi-san.

"O-Oichi-san-" Koro-sensei takes a step back out of fear. Oichi-san ignores him and steps forward. "I-I didn't do it! I swear! I-I-I don't know that your sister is an F cup or above! Sensei never even met your sister! Oichi-san! Stop!" He did a full body shudder when his back meets the wall. Fear and shock have gripped him so much that Koro-sensei actually forgot about his Mach 20 speed. Is that even possible? Then again, this is the first time Oichi-san point a weapon at him on her own accord. Not driven by the 10 million bounty or to give support in group work. She want to kill Koro-sensei for the sake of her older sister. In a way, her motive is the most honest compared to us.

"Die," Oichi-san said coldly before swinging her arm back to stab-

RING RING

Oichi-san stop her movements. Koro-sensei let out a squeak (I have this sudden urge to check if he peed himself). She lowers her weapon and pull out her cell phone. "Nee-san, what's wrong?" Her voice turn from cold to gentle. We watch her talking. "No, no. You are not bothering me. I'm just in the middle of taking out trash." Koro-sensei's shoulders slumped at the derivative name. "After school? To the police station? Okay. I understand." Oichi-san paused to let her sister talk. "Mm. I love you too, Nee-san." I noticed the warmth in her voice as Oichi-san says 'I love you'. She calms down a little now. She proceed to disconnect the call. Oichi-san gathered the bras as if nothing happened. She turn her back at Koro-sensei (he sighs in relief). His relief is short-lived when Oichi-san deliberately step onto his porn magazines. Everyone parted to make way for her, reminiscent to how the Red Sea parted before Moses.

The tension lessened after Oichi-san left. Just a little bit. Then it multiplied again. Koro-sensei has once threatened to hurt other people such as our families. Now Oichi-san's sister became a victim of his (albeit in a way we didn't see coming). As far as I know, Oichi-san did nothing to warrant Koro-sensei's ire in the past. Did Koro-sensei really do it...?

...

That was the dullest day we ever had ever since Koro-sensei became our teacher. No one bothers to assassinate Koro-sensei while Koro-sensei himself teach with less passion than he used to. Everyone avoid eye contact with him. Except Oichi-san. She give him a glare every time he looks her way. You have to give her credit though. She can take a hold of herself and not attack Koro-sensei. When Fuwa-san asked her during break time, Oichi-san simply told her that she want to save all of her energy to take care of her sister. Karasuma-sensei wanted to talk to her just then. Since Oichi-san is going to see the police, they must be talking about certain details like Koro-sensei. The bras, which are evidence, will be in Karasuma-sensei's possession for safekeeping. After class is over, Koro-sensei dejectedly leave the classroom. Oichi-san urgently stuffed her textbooks and pencil case into her back, already promising to meet her older sister after school. Without glancing at anyone, she is the first student to leave the room.

Karma-kun broke to a chuckle. "He was on pins and needles all day. Don't you think he's running away because he can't handle being here?"

"But, did Koro-sensei really do it?" I speak up. "This crime isn't a joke."

"Compared to world explosion, isn't this cute?" Karma-kun grins. I guess he does have a point... When you compare it like that... "If I were a Mach 20 underwear thief, I wouldn't suddenly leave around these ragged piece of evidence." He bent down to pull out something out from his bag. "Look, Nagisa-kun. This ball that was in the PE storage." He hold up a basketball with a bra on it. "If he did something like this, he knows he would be dead to us as teachers. For the instructor freak monster, I think losing our trust... Is something he wants to avoid as much as being assassinated."

"Yeah... I think so too," I agreed with Karma-kun. Koro-sensei is not such a person.

"But if it's not Koro-sensei... Then who?" Kayano asked.

"...A fake," A new voice joins us. I turned to see Fuwa-san coming behind Kayano, arms folded. She grins. "A fake Koro-sensei! The convention of a hero's tale! It's the work of an impostor, the evil villain!" She exclaims with fire in her eyes. "The fact that he imitates his body colour and laugh means that the culprit is someone who acquired information on Koro-sensei!" That's true... "I'll have Ritsu help me look for clues." Ritsu appears on my phone, dressed up as a detective.

"...Sounds like a plan," Karma-kun got up to his feet. "Although, I have no idea why they'd do something like this." He grab Terasaka-kun's collar. He were just about to leave. "At any rate, if these rumours spread out and our bounty couldn't stay in town anymore, we'd have nothing to gain. Also for the sake of Oichi-san's sister. Why don't we beat the hell out of the real culprit on our own and have the octopus owe us one."

"I'm joining you guys," Muramatsu-kun suddenly come up to us. "This situation just don't sit well with me."

It's settled. We are going to solve this case. I look out to the window. Oichi-san is crossing the yard. I hope she and her sister will be all right...

Chika hold her sister's hands tight. Those two are now at Kunugigaoka's police station, along with three other women. They are the latest victims of the underwear theft spree in the last few days. Toshiko-nee wear flawless make up as usual, but the younger girl knows that it's to hide the bags under her eyes. Sadly it didn't hide the red eyes. The other three women have the same restless look on their faces. Chika would look up to the clock, counting how much time have passed. Toshiko-nee is the last one to be called. Finally, several police officers and investigators came. One of them lead the sisters to the opposite direction from the other victims. They must be questioning them separately. Together they enter the conference room (Chika thinks its the conference room). There's a table with four plastic chairs, a water cooler in the corner and coffee maker next to it.

"Oichi-san, please sit down," The police officer, Kimura-san (Chika suspects he is the father of Class E's Kimura-san) gestured to the chairs. "Would you like some tea? Coffee?"

"Just water, please," Toshiko-nee answered. Chika simply shakes her head no. Kimura-san fetch Toshiko-nee a cup of water. She accepted it graciously and take a sip.

"Now, Oichi-san..." Kimura-san sits down, "Can you tell us what happened last night? It's okay to take your time."

Toshiko-nee swallowed. She turn to Chika. Chika squeeze her hand in encouragement. Toshiko-nee's features relaxes slightly. "We just finished dinner... After we washed the dirty dishes, Chika-chan went to the bathroom... The time was 8 pm... 8.37 to be exact... I went to the balcony to check if-if our laundry are dry..." Toshiko-nee paused to take a few deep breaths. "When I look outside, I noticed something dangling wildly... I thought the wind must be blowing strongly tonight... Or I did not properly put the clip on... Anyway, I opened the door and...," Her body start to shiver. "There's a head- yellow- peeking out from the balcony- He-he-he- The freak is grabbing onto my bra! That's when I scream." Toshiko-nee's eyes start to water. Chika moves closer to wrap her arms around her. Once she is calm enough, her sister continues, "I continued to scream. The-The guy just keep taking my bras... It was dark. I couldn't quite see his face... But he was large. And yellow... Very yellow..."

Chika make a mental note to avoid cooking anything yellow for the next few weeks.

"All of my bras are taken away by him... He did it so fast... Chika-chan came out from the bathroom... Our neighbours knocked on our doors... They must have heard me scream... Someone called the police... The building supervisor came...," Toshiko-nee take another deep breath. "That's it."

Kimura-san nodded, having writing everything down. "Have you seen anyone suspicious lately? Any strange activity?"

Toshiko-nee shifted uncomfortably in her seat. "Actually... I've been receiving disturbing fan letters."

"Eh?" Chika looked at her sister with alarmed voice.

Her sister give her an ashamed look, "Chika-chan... I'm sorry... I meant to tell you but-" She sighs tiredly. "I work as a model. Once in a while, I would get fan letters with enthusiastic content. I'm used to it now... But lately... This one particular guy stands out. His initial is H. There is no return address listed on his letters. At first it's once a week... Then twice a week... Next thing we knew, H sent his letters every day."

Chika narrow her eyes at the new information. It's possible that letters from H were already there when she look for Koro-sensei's (all the way back to summer vacation).

Kimura-san nodded. "Do you still have these letters?"

"Yes, the agency decided to keep everything after his letters became alarmingly frequent... In case something- something like this happened...," Toshiko-nee let out a hollow laugh, "And here we are."

Kimura-san give her an encouraging smile, "It is not your fault, Oichi-san. We can't ever predict what crazed fans would do. Now, the police will take a look at those letters. We will go to your agency and pick them up. Are there any other strange activities going on around you?"

This is her cue. If she's going to tell them, this is it.

"Ano," Chika interrupted before either adults can say more, "I have to tell you something." Toshiko-nee and Kimura-san looked at her in confusion. "There's a mysterious caller who have been calling to our apartment for the last few weeks. He never said anything. I noted down the dates and time of his every call in my diary."

Now the two adults look at her with wide eyes.

"Chika-chan! That's really serious! Why didn't you tell me?!"

"I don't want to worry you," Chika told her truthfully. "I was thinking to solve it myself," With the help of Karasuma-sensei and Bitchirina-sensei.

Toshiko-nee look at her in a weird way. Chika just can't figure out what. No doubt that she's disappointed in her... The younger Oichi feel a stab on her heart. Toshiko-nee being disappointed in her... She don't want that. She must apologise. "I'm sorry...," Chika lowers her head, unable to bring herself to look at her sister in the eye. This is worse than letting down Father or Mother.

"Then Oichi-san- I mean, Oichi-chan?" Kimura-san interject before Toshiko-nee can say anything more. Perhaps he senses an upcoming conflict and decided to interfere before it hinder the interview. "Will you let us take a look at your diary- No?" He back away a little at Chika's intense gaze. Uh uh. No way. She won't let anyone read her diary. "Or you can write it down and give it to me tomorrow?"

"Yes, Officer," Chika give the man a nod. Kimura-san asks some more questions, just to make sure everything is covered. Then he process to tell them the progress of their investigation. The culprit have yet to get caught (Figures. It's Koro-sensei). Traces of slime found in crime scene are still being processed (the Department of Defense would surely do something about that). No fingerprints have been found (Koro-sensei don't have finger prints). The police will look into the caller issue, in case other victims receive similar calls (Chika make a mental note to ask Ritsu to monitor calls to their apartment).

When it's time for the sisters to go home, Kimura-san walk them out to the entrance. The journey back home is spent in silence. Chika is too distraught to even look up to Toshiko-nee. What if she's mad at her? What if she's disappointed in her? That... Would be much worse than their parents. Chika don't want that. Yet she is too scared to talk. Toshiko-nee didn't talk either, so she can't gauge her reaction. The silence is suffocating.

Once they reach their apartment, Toshiko-nee pulled Chika to the couch. The two sisters sat down. Hands holding her shoulders tight, Toshiko-nee looked at her seriously. "Why didn't you tell me?"

Chika can feel the cold sweat running down the back of her neck. She can't get away now. "I... Don't want to trouble you. Nee-san is already so busy- I thought I could handle it by myself..."

"This is serious, Chika-chan! It's not about you being a big girl. I deserve to know!" Toshiko-nee snapped. Chika winced. "I'm sorry..." She loosened her hold. "I'm such a hypocrite... Yelling at you when I did the same thing... I'm sorry..." Toshiko-nee look away in shame.

"I'm sorry too, Nee-san..."

Toshiko-nee pull her to a tight hug. "We need to trust each other more," Toshiko-nee rests her head on top of hers.

At that moment, Chika is filled with the vehement need to spill everything. Koro-sensei, the stalker, Board Chairman. Everything. But all she can do is to keep silent and hug back.

Dear Diary,

It's been one hectic day today. Chika is too tired to even recap everything. Toshiko-nee is sleeping with Chika tonight so there won't be much time to write anyways.

Chika will tell you everything when things calmed down.

Good night.

Chika found herself sandwiched between Toshiko-nee and her bears. They all sleep on the floor (the beds are too narrow for a pair of sisters and a pair of bear). It's kinda fun though. Anyways, Chika can feel her lower part of the body feeling funny. Time to go to the bathroom. She carefully detangle herself from her sister's bear hug. Once she finished her business, the younger Oichi crawl back into the blanket. She about to lay her head down when her phone buzzes. Toshiko-nee steers in her sleep.

She quickly grab her phone and move out of the room. Ritsu is on the screen, looking apologetic. She shows her an email from Muramatsu. The subject is 'EMERGENCY! PLEASE READ'

Chika clicked it open.

"This is..."
