Anime has always had a strange talent for hiding deeply emotional stories beneath ridiculous premises. In Neon Genesis Evangelion, a teenager pilots a biomechanical god to fight angels while he spirals into depression. One Piece is about a group of pirates searching for a cartoonishly named treasure while grappling with grief, oppression, and inherited trauma. On paper, many of anime’s most beloved series sound too absurd to take seriously, right up until they land with surprising emotional weight.
That’s exactly where Yusei Matsui’s Assassination Classroom thrives. The Shonen Jump manga and anime, which lands on Netflix in June, is almost impossible to explain without sounding unserious: a class of underperforming middle school students is tasked with assassinating their octopus-like teacher before he destroys Earth. The government even places a massive 10 billion yen bounty on his head. Yet beneath the chaos, slapstick comedy, and nonstop assassination attempts is a surprisingly heartfelt story about adolescence, failure, and mentorship.
Koro-sensei is the beating heart of the story. Due to his Mach 20 speed, accelerated regeneration, and impenetrable skin, the kids eventually give him the nickname as a play on the Japanese words korosenai (殺せない) and sensei (先生), meaning “Unkillable Teacher.” Despite looking like a yellow, tentacled monster, Koro-sensei gradually reveals a deeply human side that hints at the larger mystery beneath the story.
Through their repeated assassination attempts, the students of Class 3-E learn valuable life lessons on discipline, self-worth, and confidence. These lessons are often delivered through absurd comedy that keeps the pacing consistently energetic. Students carefully stage assassination attempts during routine school activities — hiding knives in lunch trays, rigging classroom traps, or trying to ambush him during gym exercises — only for Koro-sensei to react with overwhelming enthusiasm instead of fear.
The humor works because the series treats assassination like a normal part of school life. Parent-teacher conferences, exams, field trips, and even dodgeball games become opportunities for murder attempts, while Koro-sensei responds less like a villain and more like an overly supportive teacher excited to see his students improve their technique. Assassination Classroom succeeds by using its ridiculous premise to explore relatable ideas, like failure, self-improvement, and the pressure of trying to become a better version of yourself.
Season 1 is already available to stream on Netflix, with season 2 landing on the platform on June 1, making this the perfect time to dive into one of anime’s most absurd yet poignant series. Where season 1 establishes the world and relationships, season 2 deepens the stakes, eventually leading to an emotional climax where the assassination premise becomes secondary to the students’ fear of losing the one teacher who truly understands them.
Few anime transform such an outrageous concept into something this emotionally genuine, which is exactly why Assassination Classroom continues to resonate years after its original debut.
