Ansatsu Kyoshitsu vol. 7, by Yusei Matsui, Grade B+
The test goes by quickly, and each of the 3-E students do well in their chosen subjects. Rio Nakamura takes top standing in English (because Koro had her read "Catcher in the Rye," which was on the test). Yukiko Kanzaki takes second place to Asano in Japanese. Yuuma Isogai gets first place in Social Studies. Poisons master Manami Okuda takes first for chemistry. The best student in math, Karuma, dropped from 2nd to 10th place because he didn't study. Asano dropped a couple places in the other subjects as well, so Gakuhou eggs on Asano, and Koro eggs Kuruma, to get revenge next time. In the end, the class finally gets mentioned in the school year book, and the top 50 places are dominated by either class 3-A or 3-E students. Koro is happy, because he thinks that he can easily survive losing 3 tentacles, but he's overlooked something. Gakuhou added a new subject to the tests - Home Economics. Ryouma and all 3 of his minions aced Home Ec, tying for 1st place overall in the school. Koro has to give up 7 tentacles, which puts him in a panic. However, doing so well allows the class to take a summer vacation trip to an island resort down in Okinawa. (The 3-A top four students, not including Asano, brag about getting to go to Europe, which just threatens to further tear 3-A apart, since the other students have to settle for Okinawa, too.)

The next chapter is filler. Some of the students go out to the woods behind the school to hunt for beetles to sell for cash on the net. Along with Sugino, Kayano, Kuruma and Nagisa, we have Hinano Kurahashi and Taiga Okajima. Taiga has set out etchi magazines to trap Koro, while Hinano has talked Koro into helping her find a rare albino deep mountain stag beetle, worth $5,000-$10,000 USD. Kuro knew about Taiga's snare trap all along, and he's just been using it to pass the time until capturing the stag beetle. In their exuberance in finding the beetle, the students completely miss the presence of an even rarer Japanese otter.

Lovro Brovski is back to train the class in new techniques. At the moment, Koro-sensei is killing time in a sensory deprivation capsule on mount Everest, and is being spied on by Lovro's men. (Actually, Koro is hiding in a cave under the capsule, practicing moving fast minus 7 tentacles.) Lovro teaches Nagisa a secret move, while the boy asks him about who the strongest person in the assassin's world is. Lovro answers that it's the almost mystical "God of Death" (Shinagami). During the training, both Lovro and Karasuma note that the best snipers are Ryuunosuke Chiba and Rinka Hayami. After this, everyone goes to an island resort in Okinawa, and spends the day surfing, hang gliding, and practicing assassinating Koro, while also setting up their next gambit against Koro. Some of the students receive free tropical drinks from the bartender as a "service." Irina is upset that no one is around to admire her in her new bikini, but she becomes professional when asked to talk about the importance of having backup plans during an assassination attempt. That night, the class takes Koro to a hut out on the water, and exposes him to a humiliating 1-hour documentary of all the perverted things he's been caught doing, including dressing up as a stag beetle and reading etchi magazines. The video ends, and Koro realizes that his tentacles are floating in seawater because the tide has come in. The seven students shoot off a tentacle each, as promised, then the walls of the hut collapse and a bunch of students show up on fly boards (water-powered hover boards), spraying more water everywhere. Many of the remaining students lay down a blanket of pellet fire to keep Koro from escaping, and finally the snipers, Chiba and Rinka surface from the ocean (they'd set up scented dummies to trick Koro into thinking they were on the mountain side elsewhere) and they fire the kill shots at Koro. Koro panics and there's an explosion.
(Koro was expecting water, but not fly boards.)
A few minutes later, an orange globe pops up from the water. Koro had invoked his ultimate defense - sacrificing his body to put an impenetrable sphere around his head. He can still talk, but he needs someone else (usually Nagisa) to carry him on a leash. In 24-hours he will recover, but in the meantime, he's protected. That doesn't stop Karuma from propping up his smartphone in front of Koro (who can't cover his face in embarrassment) and playing the 1-hour documentary again. The students return to the hotel, while Ritsu shows Chiba and Rinka high-speed video of their shots, indicating that the two of them had stiffened up in the clutch, and had been off by just enough as to ruin the plan. A few minutes later, half of the class comes down sick, becoming lethargic and spitting up blood. Karasuma gets a call from a mysterious villain claiming that the victims have been injected with a bio-virus, and the only antidote is at the top of a 10-story hotel building on top of a hill at the other end of the island. To get the antidote, Karasuma has to send only Nagisa and Kayano. Otherwise, the suitcase with the antidote is rigged with a remote controlled bomb and will be destroyed. The second hotel is owned by the yakuza and hosts gangsters from around the world, and spoiled trust-fund babies. Ritsu pulls up maps of the area, and Koro orders the student medics to treat the inflicted ones. The remaining kids will storm the hotel from the backdoor. Karasuma and Irina are convinced that the cliff leading up to the hotel is almost insurmountable, but Nagisa, Ryouma, Karuma and the others zip up with no problems. Karasuma settles down, and gives orders - everyone comes out alive, and they've got less than one hour to reach the tenth floor and save all the others.
