Throughout the day, Karma uses psychological pranks, such as stealing Korosensei’s special Italian gelato or leaving a dead octopus on his desk to provoke a reaction. Core Themes and Character Arc

The English Dub , featuring as Karma, is often praised for capturing the character’s "delinquent yet brilliant" energy. The episode is notable for its rapid tone switches—shifting from high-stakes tension during the cliff jump to the absurd comedy of Korosensei turning Karma’s "octopus prank" into a delicious breakfast of takoyaki.

He successfully destroys one of Korosensei’s tentacles during their first handshake by taping anti-Sensei knife shards to his palm—a feat no other student had achieved.
