Chapter 5

"Chika-chan! You're back!" Toshiko-nee welcomed her home with a bear hug. Chika can only muffle her reply because her big breasts is squashing her. "I missed you so much! Home is so lonely without you!" The woman start kissing her sister's cheek. "I already cooked dinner for you! Why don't you change first and then we can talk about your trip over dinner! Then you can show me what you bought from Kyoto!" Toshiko-nee pushes her inside. "And don't forget to wash your face!"

"Yes..." Chika answered weakly, still dizzy from the suffocation. Her sister is as energetic as always. Chika dropped her purchases in the living room before heading to her bedroom. Toshiko-nee must have cleaned it in her absence because there's no dust. Chika opened the bottom drawer of the cabinet. She hid her diary at the very bottom of it, hidden underneath her underwear. Thankfully Toshiko-nee is not the type to just waltz in but she don't want to take any chances. She even got a diary book with a lock on it.

A few minutes later, Chika emerged from the bathroom, face clean and already dressed in home wear. Toshiko-nee is serving dinner. Tonight's menu is pot stickers and hot-sour eggplants. "I've been meaning to cook Japanese food but I figured since you just got back from Kyoto... I won't be able to hold a candle against the capital." She scratched the back of her head. "But it's a nice change from western dishes, don't you think?"

As far as she remember, Toshiko never cooked Chinese before, so it might not be that bad... Then again, this is her sister we're talking about. "They look appetising." They dumplings are colourful but no whacky colour like pink or violet. Cautiously Chika pick up her chopsticks. Toshiko-nee already start eating. She choose the green one first (green usually means vegetables right?). The moment she chew it, Chika's eye twitched. The vinegar and chilli pepper is too strong. You can always count on Toshiko-nee to create an... interesting taste. She make a note to herself to cook something healthy for breakfast tomorrow.

Dinner is a short affair. Toshiko really can't wait to see what she bought from Tokyo. When the table is clean and the dirty dishes in the dishwasher, the two sisters sit down on the living room's floor. Chika told her all about her experience (minus the assassination) while they eat the green tea cookies. When the cookies are out, Chika show her the furoshiki. "Aaaaw what a cute furoshiki!" Toshiko-nee spread out a light pink furoshiki with white blossoms and blue/green lines on it. Chika is holding a blue (beige on the other side) furoshiki with red plum flowers. "This one surprisingly look mature." Toshiko-nee look at the black furoshiki with koi fishes swimming along the golden stream lines and tiny white flowers. "This one's pretty." She pick up a indigo furoshiki with butterflies.

"I thought maybe I'll cook bento for both of us." Chika start to fold everything. She've been thinking about it. Toshiko-nee said money isn't an issue because she saved up a lot since high school. But Chika don't think eating snacks only during lunch is good. Karasuma-sensei's PE lessons are very demanding. Sure, Hara-san doesn't mind sharing her bento but she feel bad. It's best for her to start eating bento.

"You would do that?" Toshiko-nee teared up. "I have the best little sister ever!" She pull Chika to another crushing hug. "Ah! But my schedule is always changing... I know! How about I leave you a message the day before so you can know when to make me bento! How's that!" She hold onto Chika's shoulder. Her sister weakly nodded. Toshiko grinned. "I love you Chika-chaaaan~" She lunged for another hug and perhaps a few kisses.

Chika swiftly dodged her 'attack'. Karasuma-sensei's lessons have made her faster than before (not that it can match Koro-sensei's speed) but she's glad that she can dodge Toshiko-nee's hug when she want to. "It's late, Nee-san. Let's go to bed. I'm really tired." In more ways than one...

Her sister grinned sheepishly. "Okay, okay. Oyasumi, Chika-chan."

"Oyasumi, Nee-san."

The younger went to her room. That doesn't mean she'll head straight to bed. Instead she walk towards her desk. Time to write another entry in her diary...

May X 20XX

Dear Diary,

Chika is back. The trip is packed with so much fun and assassination. Now where to start...?

Yesterday is Saturday so today is Sunday. School will start again on Monday. Leave it to Kunugigaoka to only give its student one day to rest and write a report about the school trip. The third years are used to it now. Chika start the day by making salad and boiled eggs as their breakfast. Toshiko-nee is going to hang out with her model friends all day. The entire apartment will be hers for the whole day. Chika have no intention of staying in though. It's been a while since she last go out by herself (that trip to the convenience store does not count). She'll work on her report in a cafe somewhere, have coffee there at the same time. A trip to the bookstore and stationery store will be nice... Finally, some alone time.

The downtown is crowded because today is Sunday but that is expected. There's a newly opened cafe that offers free cake for a cup of coffee. Naturally the place is crowded with girls. Chika managed to get the last table in the corner. The dividing screen is blocking the view so it gives her more privacy. As soon as her coffee and cheesecake come, she start to type in her laptop. History of Kiyomizu-dera, the other sites near it, the shopping experiences, how the local shops keep improving their merchandises, the impact of tourism... Those kind of things. Ah, she must check for any typos and grammatical errors as well.

"Working hard, I see"

Chika looked up to see Koro-sensei seating at the chair across her, enjoying his cup of coffee and strawberry shortcake. As usual, he wear that awful disguise (he did keep on the fake nose from Sugaya-san). "Koro-sensei, you startled me." Chika said in monotone. "Are you here because they give out free cake for a cup of coffee, added with the fact that you don't have enough money?"

"Nyu... Oichi-san, sometimes I wonder if you're just being snarky or just asking..." Koro-sensei nervously sweat. Chika simply sip her coffee. "I see that you are working on your report. Don't forget to add the experience of tasting the authentic flavour of Kyoto's pastries! Sensei still can't forget the taste of the wagashi at Ninenzakan..."

"You can just fly there and back in a jiffy."

"Yes, but this strawberry shortcake is just delicious! It's so fluffy!" Koro-sensei joyfully cut a piece and bring it to his mouth. "How was the trip, Oichi-san? Do you have fun?"

Did she have fun? Sure, the trip is also filled with assassinations but they get to work with snipers (that's pretty cool now that she think about it). Shopping with Hara-san and Hazama-san is fun. Chika get to know what their tastes are. The delinquent trio don't cause any trouble. She talked with Takebayashi-san for the first time. Sleeping in the same room with so many assassins... The story telling session with Irina-sensei that was sadly interrupted... That crowded assassination in the end...

"I had fun," She answered truthfully. "Did you?"

Koro-sensei's eyes turn softer. "Yes, me too, Oichi-san."

Chika almost smiled, almost. "You still haven't told us about your love life."

Koro-sensei tensed. "...You're still on to that?"

"You're very interested in our private life in extension to our studies and assassination. We in turn interested in you. Who knows? Maybe we will be able it to our advantage." Did he got his heart so broken that he want to take revenge on this world? But out of respect for this person, he wants to see how things would turn out? Is that person still alive? Did they have some sort of connection to Class E that prompts Koro-sensei to be their teacher? The knowledge will explain how they got to this point.

"Nyufufufufu. You won't find out that easily," His eyes turn devious as Koro-sensei eat the strawberry fruit.

"Then can I ask you another question?"

"Most certainly," Koro-sensei waves an 'arm'.

"How exactly did you blow up the moon?" The waving stopped. Chika observe the yellow octopus in front of her. That default smile got to be the ultimate poker face, because she can't detect any hint of emotion. That means she asked the right question. It's not an irrelevant subject either. Koro-sensei have displayed his destructive power (weak punches notwithstanding) but exactly what he did is never elaborated on. Is he an alien with super advanced technology? Do he have a special move like Dragon Ball's Kamekameha? Does he have an airspace hidden somewhere? Can he breath without oxygen? His home planet got blown up and he's checking if Earth is habitable for his kind? Is he the last one of his species? Is Koro-sensei a mutated being? An extraterrestrial being that somehow ended up on Earth and accidentally wipe out dinosaurs? What? What is he actually? Too much mysteries.

"That is a secret, Oichi-san," Koro-sensei finally said after a moment of silence.

Chika closed her laptop. "If there is one thing books taught me, it's that we will find out either way. In the near future, someone from your past will appear. Don't forget that your students are studying you as well. Unless we kill you first."

Green stripes appear on Koro-sensei's face. "Nyurufufufu. I like to see you try."

"Sensei, human are not supposed to change their facial colour to green stripes."

"Nyuyah?!"

May X 20XX

Dear Diary,

If you think would have calmed down after the school trip, you are sadly mistaken. Today something big happened. We have a transfer student coming in. And it's not what you think. This being the assassination classroom, no one doubted that this person will be unusual. How very wrong we are... The transfer student is not a 'person'. It's not a 'living being' either. Unusual doesn't even begin to describe it.

Our new addition hailed all the way from Norway. The student is Autonomously Thinking Fixed Artillery. In other words, a machine. No, Diary. Chika did not mistakenly write it. Class E have a machine as a student. ATFA (it's too long to write its full name) is a large rectangular robotic casing with a video screen. The Norwegian scientists have also created an avatar for it. The avatar is a girl so the class will refer her as 'she'. Karasuma-sensei explained to us that ATFA is officially a student so Koro-sensei is not allowed to counterattack or injure her in any way. Koro-sensei must treat ATFA as a student, regardless of her physical form.

First period was peaceful until Koro-sensei turn his back on us to write on the blackboard. ATFA don't waste a moment. The sides of her case opens, revealing a set of guns. Their shape are very unusual. It look like something coming straight out a sci-fi movie. She shot a barrage of bullets, perhaps as much as we did the last time. Koro-sensei easily avoid every and each bullets of course. Koro-sensei told her that firing guns during lesson time is prohibited but ATFA ignored it. The second time she fired her attach, she is able to shoot his finger. Amazing! ATFA confidently (if that's possible for a machine) state that the probability of her killing Sensei before graduation is 90%. ATFA might be able to pull it off.

Throughout the first period she keep firing her arsenal. The same thing happened during second period, all the way to the last period. ATFA keep adjusting her attacks, creating new patterns and new weapon designs. Unfortunately she is not equipped with cleaning tools to clean up all those BB Bullets. The task fell on us the whole class. Everyone is annoyed.

Cleaning BB bullets aside... Chika have to wonder if Koro-sensei's existence have triggered new technology? Now that the moon is destroyed, mankind try to come up with new ways to improve their life. The sense of urgency often push people forward, sparking a revolution (or evolution) even. It's suffice to say that the world is changing. Is the change good or bad? Chika do not know. All that Chika know that Class E is tasked to kill Koro-sensei. That way, we can find out if the world is changing for the better.

May X 20XX

Terasaka of all people took action on ATFA. He restrained her by putting tapes all over her, effectively sealing her casing. Because it is the student's action and not Koro-sensei, ATFA cannot blame him. Chika feel a little bad for her but we can't go through the same thing again. The endless barrage got in the way with lessons. One precious day is enough to widen the gap between Class E and the main building. We need to catch up or be left behind.

Chika cook a bento for Toshiko-nee today. She sent Chika a message earlier. She said the bento is delicious! Chika is so happy! Next time Chika will cook super sweet egg rolls!

May X 20XX

Dear Diary,

Koro-sensei give several upgrades on ATFA. He replaced her screen with full display LCD screen to give her full body view. The new length enable to avatar take real life size. Now ATFA's avatar is a girl wearing Kunugigaoka full uniform. Not only her appearance have changed, her personality changes as well. In order to create a sense of familiarity, Koro-sensei give her a software of facial expressions and cheerful way of speaking. The touch screen have also been applied, allowing students to 'touch' her. ATFA have a background behind her that allow us to know her current moods. Default clear sky for cheerful, cloudy when sad, rainbow when happy. Something like that. Oh and she have a music function to indicate current atmosphere.

To make it short, ATFA is like an dating sim character.

...The upgrades costs Koro-sensei his entire money though.

Takebayashi-san is pleased with the change. He said and Chika quote, "2D is just fine... Real women don't need dimensions more than that."

Otakus have an unexpectedly open way of thinking...

The upgrades proves to be a success, because the current ATFA is able to interact with students like normal person (as normal as machine can be that is). She helped out Sugaya-san when Koro-sensei asked him a question (he didn't pay any attention). ATFA showed us her ability to mold anything from these special plastic in her. Anything but guns. As long as she have the data, she can make it. ATFA also a fast learner. In 4 games she is able to beat Chiba-san in shoji. Koro-sensei seemed alarmed with her sudden popularity. His attempt to show off only made the class disgusted (he changed the colour of his skin to resemble a human face. It's so creepy). Since Autonomously Thinking Fixed Artillery is too long, the whole class decided to name her Ritsu Ji. ATFA aka Ritsu seems to like her new name.

Toshiko-nee brought back a large flower bouquet with her. She said its from a fan. It's very pretty. Certainly brightening up our living room. Chika wonders if this means we will get flowers from time to time... Our apartment might turn to a flower shop at this rate. Chika can't help but wonder if Toshiko-nee ever gotten any flowers from his former lovers... Is she seeing someone at the moment? Chika don't know...

May X 20XX

Ritsu have been downgraded by her developers. They also added to the agreement that upgrading her is the same to injuring her. So Koro-sensei will not be able to upgrade her again. Restraining her with tapes and alike will also be counted as one. We won't be able to hold on her barrage. Shockingly, instead of bullets, flowers came out. It turns out that Ritsu hid Koro-sensei's software in the corner of her memory bank. The reason why she did so is because she found that the software and 'power of cooperation' are necessary elements for assassination. Ritsu have developed her own will and decide to defy her 'parents'

The flowers are so beautiful... The petals are filling the room instead of bullets. Chika can tell that she genuinely wants to be part of Class E. It really is a heartwarming moment.

Chika have to wonder though... Does everyone consider Chika as a part of the class? Chika never try to assassinate Koro-sensei before... She also never create any plans... And barely inputs... Chika really need to start smiling... But for some reason Chika just can't... What should Chika do, Diary...?

June 1st 20XX

Dear Diary,

We're entering the third month of the first term. There's 9 months left until the deadline. The rainy season is here. The hydrangeas are blooming. Toshiko-nee don't particularly like rains because it will hinder her work. Outdoor photo shoots depends on the weather. Rain will force the schedule to change. Chika don't particularly mind rains. Chika always found the sound of rain soothing. The smell of rain is very unique. Do you know that it actually came from plants? When plants are in drought they produce oils in replacement for waters. When the time comes and it finally starts raining the plants get their needed water and they release these oils in the air and the smell of that oil is what we call smell of rain. The scent is called perichor.

The school building do not agree with the current weather though. The rundown parts cause leaking. We are forced to put buckets underneath the leaks to prevent puddles indoor. The air is so humid it causes Koro-sensei's head to bloat up. Apparently his head absorbs moisture. The air is so humid, mushroom grows on top of its head. Koro-sensei claimed that it's hair though. Shiota-san jot this down (Chika will also write the weaknesses he noted during the trip).

Koro-sensei's weak point#11: He worries about appearances

Koro-sensei's weak point#12: He can't handle hot food

Koro-sensei's weak point#13: Getting wet

Sadly, nothing can be done about it. At times like this Chika missed the main building with their air conditions. Thankfully we haven't done laundry yet.

Kayano-san asked Chika if she want to go home together. This is the second time Chika's classmate asked Chika to hang out together after school. Of course Chika said yes. Shiota-san, Sugino-san and Okana-san also came. Chika think this is the first time she go home with boys... (After student council that is). We made a quick stop at a pudding shop. Kayano-san loves pudding. Chika decided to get one herself. Strawberry flavour for Kayano-san and custard for Chika.

Along the way, we saw Maehara-san walking with Tsuchiya Kaho from Class C. Chika was once in the same class with her back then in our first year (Chika was in class 1C). Tsuchiya-san is a bit boy crazy. She always have her eyes on someone. This time it's on Maehara-san. Tsuchiya-san have a bad habit of having multiple boyfriends at the same time. Her type are those who are popular and will make her look good. She once ditched the smartest boy in Class 1C for the soccer player from Class 1B.

Okana-san is the first to noticed them. She is always annoyed with Maehara-san's playboy tendencies. ...Could it be that Okana-san is attracted to Maehara-san but denies it?

Back to the story, it appears those two are going on a date. Never one to miss any details about his students, Chika is hardly surprised when Koro-sensei appears, writing something in his notes. Sugino-san said the content is love gossips. Koro-sensei claim it is the teacher's duty to keep track of their students' affairs... He intent to publish a non-fiction novel by the third semester of all the students' love stories.

...Chika don't have her first crush yet, moreover a love story...

Koro-sensei said the first chapter will be about Sugino-san's feelings for Kanzaki-san but unable to reach her...

...

Chika will definitely buy that novel!

Maehara-san's chapter will be long according to Shiota-san. Maehara-san is really popular after all. Chika remembered her former classmates gossiping about him. Then trouble came. Seo-san, Araki-san and Goto-san appeared! Tsuchiya-san immediately ditched Maehara-san. The way she called Seo-kun give it away. It seems Tsuchiya-san have yet to give up her playgirl ways... Maehara-san instantly realised what's going on. When Seo-san get angry, Tsuchiya-san immediately switched sides. She start berating- badmouthing Maehara-san, now her ex boyfriend.

Things start to go downhill when Seo-san kicked Maehara-san to the ground. Teppei-san and Goto-san also joined in. Three against one. Not fair. In human terms that is. Then the devil himself descends... Chika is talking about Board Chairman, not the devil version of Koro-sensei. His car just passed by. Chika immediately feel sick at the sight of him (at least his son isn't around). Board Chairman offered Maehara-san a handkerchief while scolding the three council members... And then he give a warning to Maehara-san. He is this close to get expelled.

It's not fair. This whole thing is not fair.

Sugino-san called her a bitch. A different bitch compared to Irina-sensei. Shiota-san found the reason and focus of Irina-sensei's bitchiness reasonable but Tsuchiya isn't as sophisticated as hers. Okana-san gave Maehara-san a towel to clean himself. Maehara-san tried not to look too bothered but he's not fooling everyone. He's hurt. The strong is able to toy with the weak simply just because they are terrifies him. What if he is not of Class E? Will he bully class E like them? That though terrifies Chika as well...

Koro-sensei is even more pissed than us. He want to retaliate for the unreasonable humiliation. He said to us that we are all strong. We are assassins that are able to kill a target without being noticed or leaving proof. An eye for an eye. Time to give those two an even greater dose of humiliation.

Diary, this is what it feels like to be wicked.

Sugino POV

I watched the couple drink their coffee outside of the cafe. Today is raining as well but it don't hinder them at all. Instead, it's the perfect touch for their plan. Still, the information from Oichi is spot on.

"Tsuchiya always bring her boyfriends to this cafe on Y street after school. She always brag that she get special treatment there because the cafe is owned by her father's friend. They will sit on the outside. Tsuchiya will order at least one cup of coffee. Seo-san will most likely to order coffee because its his favourite. He have this habit of putting his feet on desks or other chairs. The date will last for at least 40 minutes. That should be plenty enough time. Right across the cafe is a private housing building. That should be the perfect spot for observation."

Oichi who is in charge of strategy is sitting between him and Sugaya, holding a binocular of her own. She know all these facts because she was in the same class with Tsuchiya back in first year. Not to mention she is a former member of the student council. Oichi have spent time with Seo before. Sugaya is in charge of disguises. He revamped the party masks they found in the storage for this operation. Nagisa and Kayano will disguise as a pair of elderlies, wearing those masks. They are in charge of creating a distraction. The masks will be enough to fool those two. After all, they have no interest in people who appear to be weak. Yada and Kurahashi negotiated with the landlord to let them borrow the room on the upper floor. They will keep him busy until the completion of this operation.

Okuda provide the special BB bullets for Chiba and Hayami. At the cafe, Kayano went inside to go to the restroom. Nagisa 'accidentally' knock over his salad. When all the attention shifted to Nagisa, Chiba and Hayami shoot the BB bullets into their coffee. Compared to hitting targets moving at mach 20 speed, that was easy. Everyone except Oichi smirked when those two drink their coffee.

"I mixed these using magnesium as the main ingredient. It causes bowel irritation much stronger than that from over-the-counter drugs." Okuda explained while holding up one of her creation. "In short, it's a powerful laxative. I call it 'Victoria Falls'" She start to chuckle. Her glasses glinted dangerously.

Victoria Falls work perfectly all right. They watched as the couple dashed inside, only to run back out in less than a minute. The rest is up all up to everyone on the ground. Isogai, Maehara, and Okana will cut off tree branches when the timing is right. When Tsuchiya and Seo are right underneath their range, tree branches will fall on top of them. Time for them to leave as well!

"That was quite refreshing, won't you say?" Koro-sensei chuckled as they gather outside. "Making a mad rush to the bathroom while looking dishevelled will be extremely humiliating for those two." All of us start to grin again, mimicking Koro-sensei's signature grin. Except Oichi. I don't think anyone ever seen her smile.

Maehara looked embarrassed. "Erm... How to put this?" He scratched his head "Thanks... For doing all these for me..."

"What's the matter, Maehara-kun? Do you still believe that you are sort of person who would calmly torment the weak?" Koro-sensei asks him.

Maehara contemplates for a moment. "...No. Watching everyone just now, I realised it would be impossible for me. At first glance, you guys don't seem strong, but everyone possesses a hidden weapon they can rely on. A ton of weapons that I don't have..."

"That's how things are," Koro-sensei slapped a tentacle behind his back. "Strength and weakness can't be determined by sight alone. That's why you, who study while attempting assassination in this class... Will likely find it difficult to look down on the weak in the future."

His words brought up a smile on our faces (except Oichi).

"Crap, I've got a dinner date with a girl from another school. Later, guys. Thanks again and see you tomorrow!" Maehara waves around as he start to leave.

Everyone's face turn to ( . _ . ) emoticon.

Except Oichi of course.

This chapter takes place from Ch. 20 - 24 in the manga.
