Description
In the RPG-themed spin-off's alternate universe, Korosensei embodies the Demon King. He deliberately mentors Class 3-E, students viewed as flawed "heroes-in-training" due to in-game bugs hindering their abilities, preparing them to ultimately defeat him. His motivation springs from achieving every heroic feat possible, leaving him profoundly bored with invincibility. Seeking purpose, he accepted a position from Aguri Yukimura of the Temple of Trade, transforming into his distinctive yellow octopus-like form via a magical robe. This role shift channels his powers into educating the class. His primary goal is fostering the students' growth until they can overcome him, specifically targeting his maximum speed stat of '99999'.
As instructor, he crafts quests and combat challenges tailored to each student's unique weaknesses and bugs. For Nagisa Shiota, he leverages the randomized bug causing unpredictable physical or temporal shifts, utilizing Nagisa's ability to equip female-exclusive gear due to his feminine appearance. He guides Kaede Kayano through her self-perceived bug related to small stature and chest complex, and helps Karma Akabane manage his severe luck penalty when displaying arrogance. Training involves dungeon exploration, joint exercises with other classes, and specialized trials like the Ruins of Tribulation, testing observation, trust, and tactics.
His personality blends eccentricity with genuine mentorship. He exhibits theatrical villainy through dramatic entrances and declaiming world-ending threats, while simultaneously demonstrating patience and perceptiveness toward students' emotional and strategic needs. This duality includes playful tendencies—like enjoying hotpot parties and skiing—and decisive protectiveness when students face external dangers. His teaching merges encouragement with rigorous demands, spurring innovation and collaboration. During a body-swapping treasure hunt, he supports the abandoned Ryōma Terasaka's solitary training, resulting in Terasaka reaching level 99 as the class's strongest member. Korosensei's black academic robe and crescent-patterned tie visually reinforce his dual role as educator and final boss, symbolizing his commitment to their development until they can assassinate him.
