Chapter 15


Nagisa POV

The day we go to the resort is getting nearer. With Koro-sensei gone to Mt. Everest, now the class can strategies and train without interruption. Before we can start our training, first we must figure out how to kill Koro-sensei. The plan we come up with is simple enough. First we lower his reaction time by giving him psychological attack. Mimura-san and Okajima will create a video featuring all embarrassing materials we have on our teacher. Then those who won the right to destroy his tentacle will make good of that promise. Without pausing, the entire class will shoot simultaneously to bring him down. That is the outline of the plan. Now we need to crack down the details. Unlike this mountain, the resort island is an entirely new environment for us. We need to check every nook and cranny when we are actually there to adjust our plan. The pamphlet helps but not enough. For this operation, Hayami-san and Chiba-san will be the clincher. Those two are the best snipers in Class E.

From the back, Oichi-san raised her hand. "We need to do something to prevent him from escaping to the air."

"Then we should do it in a closed up space," Isogai-kun suggests. "Or we can create one."

This time Kimura-san raises his hand. "How about we use the flyboards to create a water cage around him?"

Everyone like the sound of that. Koro-sensei is weak against sudden change of environment. The only building surrounded by water is the chapel. Karasuma-sensei will ask permission from the hotel to use it anyway we like. Chances are it will be teared down after we executed our plan. The resort will also be fully reserved for Class E. It's a shame that there won't be any women in bikini to distract Koro-sensei but the populace must be left alone. Since the winners will have to stay on the ground, those with athletic abilities will be the one using the flyboards. The rest will be shooting from the ground. Kayano can't swim well, so she will be standing by the wooden path.

Kurahashi-san raises her hand. "I read in the dolphins that they are dolphins! Maybe they can help!"

A unique idea. We will consider that in later date.

Oichi-san raised her hand again "Koro-sensei told me just recently that his senses are as great as the vampires from Twilight. The novel is ridiculous but at least it give us an estimation of how great Koro-sensei's senses are. It is still unclear if he has night vision or not. So we need to hide Hayami-san and Chiba-san so he won't be able to pinpoint their exact spot. Be it by sight or smell." She look towards Chiba-san who is somewhat agitated. Hayami-san shifted uncomfortably. I wonder if something have happened.

"Chiba-san, Hayami-san. Is it okay for you two to stay underwater for an hour?" Isogai-san asks them. The two nodded in affirmation.

"Then how about we practice at the pool? We still need to watch out for the tides. Wouldn't want you guys to get injured before doing the actual thing. I'll help you." Kataoka-san offers. So dependable. "We can ask Karasuma-sensei for the diving equipment. Ritsu will help with calculations." The AI saluted them when Kataoka-san turn to her.

Everything is falling into place. We can do this. We'll kill Koro-sensei. This time for sure.

Okajima-san suddenly grins. "I can't wait to see babes in swimsuits!"

"The Summer Arc plot thickens!" Fuwa-san snickers.

...Okajima-kun... Fuwa-san...


August X 20XX

Dear Diary,

Lovro-shi came to visit us today. He will be our special instructor during the summer break. He gave us advise regarding our strategy from a pro's point of view. It was nerve wrecking to be observed by a hit man other than Irina-sensei. He didn't use any demeaning words though. Lovro-shi is so polite. He told Chika that she do better at shooting when she draw up her knee. A pro really knows what he's talking about. Lovro-shi is so cool. With him here, Irina-sensei can't slack around.

He told us that won't send out assassins for a while. Koro-sensei have learnt the signature of a pro's bloodlust. Many have came to Kunugigaoka but Koro-sensei stopped them before they were anywhere the school. Lovro-shi won't be able to sent a same hitman twice. On top of that, a number of promising hitmen suddenly goes missing. If we use the laws of TROPES, this is what you would call 'Foreshadowing'. Sounds eerie, Diary. Chika hope the assassination will go well.

Shiota-san seems to be interested with the hit man occupation. Earlier today he asked Lovro-shi about his job. Lovro-shi seems interested in Shiota-san. He even taught him an assassination technique. It looks silly at first but Lovro-shi assured us that it is a very useful technique. We'll see how effective it is against Koro-sensei in the future.

Lovro-shi also told us one more thing. The greatest hit man is nicknamed God of Death. The initial would be G.O.D. God. Clever. A phantom whose elusiveness only matched by their cruelty. He (or she (or they)) will appear sooner and later according to Lovro-shi. Koro-sensei VS the best assassin in the world. That will make quite the battle. It will be interesting to see the God of Death fight one-on-one against Karasuma-sensei. He's a superhuman in his own right. But you have to admit Diary. Anyone using the word 'God' as part of their nickname have to be narcissistic.

Chika must admit. She want to talk more with Lovro-shi. His firsthand knowledge about assassination will make quite the material for writing. The mechanics, the lifestyle, the drama. Chika knows she can ask Irina-sensei anytime but hers are mostly honey pot mission. Not to mention Lovro-shi is older. He've seen war zone, judging from his ethnicity. The name Lovro originated from Eastern Europe. He is definitely old enough to remember the Cold War, as well as the fall of Soviet Union. Chika must learn more about that period. Who knows? It might give us lead about Koro-sensei.

Toshiko-nee will take Chika to buy swimsuit tomorrow. She insisted. Chika hope her period won't start during the assassination. Sure, Chika can wear tampon but she never go swimming with tampon before. Moon cup is still a bit...

Hayami-san and Chiba-san spent the day avoiding Chika. Chika wonders if they are dating. Chika now wrote a couple of stories about them.

Chika wonder what Horibe-san is doing right now. Will he show up at the island? He failed assassinating Koro-sensei twice. Rules of three dictates that his third time will be the last one... What will happen to him after that? Will he keep working with Shiro only? Who is Shiro anyways? It's eerie how much he knows about Koro-sensei... Not even Karasuma-sensei know that much... There is only one explanation for this. He was directly involved with Koro-sensei. How else Horibe-san have tentacles? Wait... What if Koro-sensei was once human...?


Chika paused in the middle of her writing. Koro-sensei... Once a human...? That's a possibility... Koro-sensei said that he is an artificial life form... He is born on Earth. Maybe a cloning experiment gone wrong? Never Let Me Go by Ishiguro Kazuo is a novel that covers human cloning. All clones in fiction have a complicated life. Chika remember that there are clones in the Gundam franchise. Well... If it's cloning or artificial life form, science is the link. Science... That's Okuda-san's forte. Chika wonder how far her research is with that spray substance Terasaka got from Shiro. If only they have Shiro's gadgets... Maybe Ritsu will be able to recreate the gadgets Shiro used. Chika continue her entry.


Regardless of what Koro-sensei was before coming to Class E, our objective stay the same. Assassinate Koro-sensei. Anything that sway Chika will make the situation worse. Chika will not repeat her mistake from the second year's last exam. Chika was distracted because of her parents' split. Chika won't be swayed again. This time will be different. This time it is not just Chika. Class E is in this as well. Chika must do her best to support the others. Chika must not mess up. One mistake can ruin this whole operation.

Chika just realised she never think of what she will do when she get the prize money. Half of it will go to her savings of course. Chika must think ahead for her golden years (And Toshiko-nee's). The other half though... It felt really nice when Koro-sensei took Chika to England. Maybe Chika will go on a pilgrimage to famous writers' hometowns. Ernest Hemmingway, Stephen King, Sylvia Plath, Leo Tolstoy, Maya Angelou, Oscar Wilde, Victor Hugo, J.D. Salinger, Jean-Paul Sartre, Herman Hesse. America, France, Russia, Germany... Ah! Chika feel really excited now! And for It will be best if Chika go to bed now.

Before Chika call it a day, Chika want to apologise to Diary. Chika can't bring Diary with her to the resort island. Chika won't put it pass Koro-sensei to secretly read you Diary. Same goes to Nakamura-san and the boys. Chika promise that Chika will write a looooooooong entry when Chika get back. Thank you for being so understanding!

Good night Diary.


Predictably, Toshiko-nee is very chipper the following morning. She will always be chipper when shopping is involved. Chika barely finishes her breakfast when her older sister whisk her away. "Summer is not summer unless you go swimming! Swimming means swim suit! Swim suit means something not from your school! No, Chika-chan. You can't wear swimwear from your school!" She said sternly when Chika give her a blank look. "So what do you have in mind? Daring? Cute? Sweet? Mature? Seashells are not allowed! You're still in middle school!" Toshiko-nee crosses her arms, making the sign 'X'.

"Nee-san, I don't think the sports store is open now." Chika said calmly, fixing her bun. "It's still too early."

"Ah" Toshiko-nee glance at her phone to check the time. "Sorry" She grinned sheepishly.

Since they are already outside, better to go along with it. "How about we go to the department store to buy necessities for the resort? Like sunblock. We're out of those."

Toshiko-nee clapped her hands, grinning. "That's right! Summer this year is a toughie! Well? Let's go!" She pull her hand again. "Should we go to Taiheyo Shopping Mall again?" Chika nodded. Taiheyo's department store is quite nice. "I'll keep myself in check this time. Don't worry." She bumped her shoulders playfully to Chika's. "We should check if they sell yukatas as well! It's been a while since you've gone to a summer festival, am I right Chika-chan?" Chika nodded again.

Summer festival... Chika only been there once in her life. It was her last year on kindergarten. Their parents are too busy with work so she went there with Toshiko-nee. She wear her sister's old yukata, a light blue yukata with goldfishes. Toshiko-nee herself is wearing a white yukata with pink and blue yukata. Toshiko-nee spent hours putting on yukatas for the both of them since their mother wasn't there to help. Numerous magazines spread on the floor as Toshiko-nee keep glancing at the tutorial as she work. Her sister insisted on doing an elaborate bow for Chika's obi. It was tough but somehow they did it. The festival itself was very fun. Chika tasted her first cotton candy there. She tried so many food for the first time. Candy apples, takoyaki, choco banana, karumeyaki, shaved ice. Oh God, the shaved ice... Her first case of brain freeze is something memorable indeed. Toshiko-nee bought her water balloon yoyo. Chika tried her hands on with the shooting game but failed. Years later, she is taught how to shoot. Funny how the world works. Their time at the summer festival is the first time Chika got a stomachache not from Toshiko-nee's cooking. She ate so much there. And the fireworks. They are just... Beautiful.

That night was ended with little Chika sniffling because her foot got hurt from her geta sandals. Toshiko-nee carried her piggyback all the way home. Her sister disinfected the wounds and put Hello Kitty bandaids. Toshiko-nee tucked her in. Chika slept soundly that night. She have no memories about it but she remember that she had a good dream. This year... She will attend her second summer festival... This time with Class E and Koro-sensei. It will be a lot of fun. What kind of crazy things Koro-sensei will do there?

"Nee-san... Are you going to summer festival this year?" Chika asks as she reach for her sister's hand.

Toshiko-nee smiled sadly. "Unfortunately, I can't. I have to work on a runway that day. The theme is 'End of Summer'. Summer festival this year fall on August 31st. Very convenient don't you think? But don't worry!" She bump her shoulders again. "We still have Christmas! And another summer festival next year!"

'If the Earth survives Koropocalypse,' Chika mused. Then she remember something else. Something unpleasant. A matter that she must discuss with her sister, sooner or later. "Can I ask you something, Toshiko-nee?"

"Anything for my dearest sister!" Toshiko-nee giggled.

Chika swallowed. "Have you... Heard anything from our parents...?"

The relaxed smile on Toshiko-nee's face turn to a frown. Her usually spirited eyes turn serious. "Oh. Them." She mutters icily.

"I'm sorry." The younger sister looked away.

"No, no. It's okay, Chika-chan. Don't be sorry." Toshiko-nee give her hand a squeeze. "I'm just caught off guard with your question. Well..." She sighed loudly. "I haven't heard anything from them directly," Chika's shoulders loosen hearing that. "Though according to my sources, aka the grapevine, their divorce process is nearly finished. Those two take an awful long time to settle this. No doubt screaming at each other every time they met. I pity their poor lawyers." Her big sister let out another sigh. "My estimation suggest that they will be officially separated some time this year."

Chika nodded. That sounds about right. Their parents are already living separately anyways. If you can call your father opting to sleep in hotels rather than seeing his wife's face. Chika wonder where are they living now. Are there anyone still living in their old home? Another thought come to her and it cause her to freeze.

Toshiko instantly noticed. "Chika-chan? What's wrong?"

"What if... They start fighting for custody over me..?" Chika asked fearfully. She can't deal with those two. If they start using her as a pawn in their game to spite each other-

"Chika-chan, look at me," Toshiko-nee cup her face. She lower herself so the sisters are on eye level. "I won't let any of those two awful people to get their claws on you. Don't even think that I would abandon you. Again." Toshiko-nee grimaces. "Who says it will be a battle between the two of them? It will be a three way battle... Your sister too will fight for you. But unlike our parents, I do it because I genuinely love you, Chika-chan. I already left you with them for years. I have so many regrets. Leaving you behind is one of them. I'm not going to make the same mistake again. I'm not going to leave you, Chika-chan." Chika is pulled to a really tight hug.

Her sister was 16 when she ran away. Their parents made no attempt to chase her or at least support her financially. They readily abandoned her. All because she is not the model student they want her to be. Toshiko-nee was under pressure. She have no choice to leave. Her mental state won't be able to take it anymore in that environment. Chika is glad that her sister didn't take the suicide route to escape. There were so much news about suicides at the time. At the time, Chika was gullible, susceptible to their parents' toxic influence. Now, older and wiser, she knows better. Chika is glad that Toshiko-nee got out.

"I don't blame you, Nee-san," Chika pat her back. "You were 16. You can't possibly take care of me at the same time. I'm just glad things works out for you. And look at where we are now. On our way shopping."

Toshiko-nee let out a sob. Is she crying? Suddenly her sister let her go. She is grinning widely though Chika can see her glassy eyes. "Yeah! Shopping! One of the best cure around! Look at us! Getting melodramatic in the middle of the street. In daylight even! Come on, Chika-chan! Taiheyo Shopping Mall is waiting for its favourite sister duo!" She pull her hand. "Let's run! Great way to get your blood pumping!" Running? In this heat? Is she trying to distract herself so she won't cry..? "We'll buy ice cream when we get there!"

Chika stare at her sister, admiring the way her brown red hair flutters. Toshiko-nee is so beautiful, so spirited, so strong. Even so, she can be so vulnerable. Chika just witnessed that. Her sister love her so very much. Chika love her just as much. This summer will be an unforgettable one for her. She can just feel it. Summer is the time you learn more about yourself and others. Chika have missed out many years of Toshiko-nee's life. It's time for both sister to catch up those lost time. To treasure every moment that have almost been stolen from them. To do sister things. Chika must look up the internet for that. Wonder who in Class E that have sisters...? Or older siblings? Horibe-san claimed that Koro-sensei is his brother. Not the best example.

Oh right.

Firstly, let's go shopping.


Karumeyaki = grilled caramel
