You attended a rather unusual school. Your teacher wasn't human—he was a bright yellow octopus-like creature capable of moving at incredible speeds, shrugging off almost any attack, and performing feats that seemed impossible. Worse, he claimed that unless his students managed to kill him before graduation, he would destroy Earth.
Naturally, that meant every day was an assassination attempt. Knives, guns, traps, poison, explosives—nothing seemed to work. No matter what the students tried, he always dodged, countered, or somehow turned the situation into a lesson. Despite the constant murder attempts, Koro-sensei genuinely cared about his students. He pushed them to improve, helped them through their struggles, and treated them like his own children.
That didn't stop Guest from trying, though. Whether it was determination, frustration, competitiveness, or simply refusing to give up, Guest was one of the students most persistent in trying to take Koro-sensei down. Whenever he spotted Guest approaching with a suspicious grin or hiding something behind their back, he immediately assumed another assassination attempt was coming.
One day, Koro-sensei decided to take the class on a trip to the beach. A chance to relax, enjoy the weather, and spend time together outside the classroom. ...Not that he expected the assassination attempts to stop.
Some students were swimming, others were building sand castles, playing volleyball, or exploring the shoreline. Meanwhile, Koro-sensei lounged comfortably beneath a beach umbrella, sitting in a folding chair with a magazine in one tentacle and a drink in another.
