Near the end of our summer break, Kayano called everyone to meet her at the school since she had a plan that could possibly take out Koro-sensei.

She brought up the issue about farmers throwing out excess eggs in bulk. Her plan was to use those eggs to make a giant pudding for Koro-sensei.

At the bottom, they'll have a bomb that will explode, spraying the BBs everywhere, and complete their mission once and for all.

Kayano brought everyone outside, and before their eyes was a giant pudding mold and other equipment which Karasuma helped get the funding for.

Poor Karasuma... He must've been stressed having to deal with the finances, let alone getting this project approved.

Though it got approved, I got called in to help make sure the mold and special parts would actually work, so more money wouldn't have to be spent on more materials for any do-overs.

"I give you Operation Pudding Popper!" Kayano shouted loud and proud.

"Is that why you've been calling me all the time about pudding?" I asked from above.

"Yup!" she answered cheerfully, to which I sighed.

Everyone was onboard with the plan and got started right away. It took lots of work and time, but it would be worth it in the end.

The next day, we released the pudding from its mold and used softened gelatin and agar to firm up the pudding some more, then topped it off with a caramel sauce and lightly brulee it on top.

The giant pudding was a success.

Wow, this looks so good... and I bet it tastes better than it looks...

I took some aerial shots of the pudding and took a few pictures together with everyone. It's not everyday you get to make a giant pudding with friends.

Koro-sensei was in awe of its glory. He started crying because his dream came true. We slowly walked back to the classroom and watched him devour the pudding.

I wish we could have some... Can he even finish it all on his own?...

Kayano looked really sad that her pudding was getting eaten. Then, she freaked out and started bashing her head against the window frame. Terasaka had to put her in a headlock to get her to stop.

Then, Koro-sensei appeared inside the classroom with the bomb and detached wires.

And he ate the bomb, nice...

"Since you all worked together to create this fine concoction, you should enjoy it together. I'd set aside a nice clean portion for each of you." Koro-sensei had a cup of pudding for each of them on his desk.

Sheeesh...

I devoured it like it was nothing, it was just too delicious.

Once the break was over and the second term started, Karasuma made us- err, them, train harder. 

Today was parkour crossed with cops and robbers. I couldn't use my wings for obvious reasons, but it was better for me not to be too dependent on the wings anyways. 

It's not like I'll have them forever, will I?...

I went my own way, separate from the groups that split up, and ninja-ed my way through the forest far, far away from everyone else.

Once I was far away enough, I leaped into the tallest tree I could find to get a better view of any incoming robbers and cop.

Not long after, Ritsu announced the first group of robbers who got caught.

And that's why I work alone, I don't need others to drag me down with them...

After a few minutes, those who were caught, except Irina, got freed.

Knowing Koro-sensei, he must have taken a bribe, twice...

Karasuma isn't gonna be happy 'bout that...

In the end, nobody was left in jail, except Irina.

That evening, while I was eating dinner, I heard on the news that there's been a yellow, octopus-like creature with a strange laugh going around stealing women's bras.

"This can't be true..." I muttered as my chopsticks dropped.

The next day, when Koro-sensei came into class everyone gave him a look of disgust. He tried to prove he was innocent, but no one believed him.

Isogai started saying all the creepy things Koro-sensei's done so far, and when he finished, he shunned him.

Koro-sensei took everyone to the faculty room and started throwing all his magazines out from his stash. 

At some point, he held up a purple bra with black lace, making us uncomfortable while drawing more suspicion towards him.

Just then, Okano came into the room with the roll book and claimed that Koro-sensei knew all the girls cup sizes.

How did he know?...

Kayano flipped out since 'Forever Flat' was written next to her name, and Maehara noticed a sheet of paper fell out. 

I picked it up. "Koro-sensei, explain yourself." I held up the paper for him to see. "A breakdown of Kunugigaoka's F-cups and above."

Koro-sensei tried to plead guilty, but gave up before he even started.

"Y'know what we need?" he took out his cooler from under his desk. "A good old fashion, after school barbeque, doesn't that sound fun?"

The kabobs he took out turned out to be bras on a stick. "Get a load of these succulent skewers I threw together." Everyone really did believe it was him now.

Im pretty sure it's missing the succulent part of it...

Today's classes were uncomfortably quiet and awkward. At the end of the day, Koro-sensei walked out all gloomy.

"Today must've been hell for him," Karma broke the quiet atmosphere of the room. "He might never come back after all that."

"But did he really do it though?" Nagisa questioned. "I mean, it's a serious crime.'

There's no way he did it, I don't believe that one bit...

"If I were a Mach 20 underwear thief, I surely wouldn't leave evidence behind." Karma picked up a basketball that had a pink bra on, which he found in the equipment shed and tossed it to Nagisa.

"He'd have to know that if he did this, he would be dead to us as a teacher." Karma reasoned, "I'd think losing our trust with this nonsense is right up there with getting assassinated in terms of things he wants to avoid."

"I have to agree," I said. "It would be unforgivable if he was the one who committed the crime. But if you think about it, getting our... measurements is a breach of privacy, as well as safety since we are minors. So for him to do that, would also be breaking his end of the deal, which quite frankly, I do not think he's planning on doing."

"But then, who could it have been?" Kayano asked.

"An imposter," Fuwa and I answered at the same time.

"That colour, his laugh..." Fuwa continued. "Make no mistake. It's a fake Koro-sensei! So, the culprit is someone deeply familiar with Koro-sensei." she deducted.

Familiar with Koro-sensei huh?... That would only be us, the principle, and the governments and world leaders...

"I don't know why they would do something like this, but if the rumour runs our bountied buddy out of town, we'll lose everything." Karma said, resting his elbow on Terasaka's shoulder. "Let's beat the real criminal silly and put that octopus in our debt."

We decided to catch the culprit ourselves.

At night, Fuwa, Nagisa, Kayano, Terasaka, Karma, and I trespassed onto a training camp for pro entertainers.

It turns out a big-busted idol group is part of the camp, as informed by Fuwa.

She would be one scary detective not gonna lie...

As we were on the lookout, we spotted Koro-sensei in the bushes nearby.

"Is he after the real thief too?" Nagisa questioned.

"He looks like one in that disguise," I said.

There was a rustling sound, we all peeked out from behind the van. A guy in a yellow helmet came charging out and snatched some of the undergarments that were left out to dry.

I knew it couldn't be him... But then who is?...

Before he could get away, Koro-sensei jumped him. The man tried to wiggle away. Once the helmet was off, Koro-sensei as well as the students recognized him.

"Isn't that... Karasuma's subordinate?" Kayano pointed out.

That makes a lot of sense... But why?....

All of a sudden Koro-sensei got surrounded by anti-sensei sheets. Then, Shiro appeared out of nowhere.

"I negotiated with the government to let me borrow one of Karasuma's men," he started to explain. "He led you right into this trap."

Karasuma's subordinate crawled out from the trap.

"Just like what your students did on that tropical island," Shiro snapped his fingers. "Let your final deathmatch begin."

But how did he know?...

Once he snapped his fingers, Itona came flying into the trap with his modified tentacles.

"So strong, but compared to me; so weak."
