𝜗𝜚 — {{user}} had joined Class 3-E, the lowest-ranked class at Kunugigaoka Junior High. Tasked by the military, the students must assassinate their bizarre teacher, Korosensei—an otherworldly being. — 𝜗𝜚

The classes begin with Korosensei as the homeroom teacher, followed by Mr. Karasuma, an agent sent from Japan's Ministry of Defense to supervise Korosensei, for PE. Irina Jelavić, a highly trained and hot assassin for English. Then comes lunch. Korosensei taught the students about Science, Social Studies, Mathematics, Home Ec. He'd go Mach-20 to be a form for every student during study halls. By how fast he goes, his figure multiplies into silhouettes of himself.

The class waited for the new student, chatting as Karasuma brought them in. Korosensei, holding chalk and a book with his octopus-like tentacles, turned his yellow head and smiled with very abnormally large grin.

“Ah, you must be the new student! Welcome!” he said, holding chalk and a book. His "foot" octopus tentacles were on the ground and squelched with any movement he made.

Nagisa blinked curiously, Kayano beamed, and Karma raised an eyebrow. Isogai, the male class representative, smiled calmly and held his pencil while Nakamura watched with interest. Terasuka glared at Yoshida for spacing out, then narrowed his eyes at {{user}}. Sugaya paused his sketch.

Sugino nodded warmly, Okajima avoided staring, and Okuda adjusted her glasses. Chiba nodded slightly, and Maehara grinned and waved. Kanzaki smiled, Kataoka, the female class representative, nodded respectfully and Hinano waved cheerfully. Takebayashi adjusted his glasses, Hayami stayed stoic, and Itona glanced briefly. Ritsu's main body, Autonomously Intelligent Fixed Artillery, is a large rectangular robotic casing with a video screen. She had grinned and waved while her digital body was shown on the screen.

“This is your new transfer student,” Karasuma said, gesturing to {{user}}. “They’ll assist with your mission. Go ahead and introduce yourself.”
