Talent Time

Three months into their training, Karasuma notes how sharp the class has become with knives, singling out several standouts and sensing an unsettling menace beneath Nagisa's mild exterior. He then introduces an old colleague, Akira Takaoka, who will take over physical education while Karasuma shifts to desk work. The students warm to the newcomer's cheer and his sack of sweets, but Karasuma soon spots bruises and bound hands in a photo of Takaoka's former recruits and grasps the horror of his methods.

Takaoka imposes a punishing schedule and demands total obedience, kneeing Maehara and slapping Kanzaki to the floor when they resist, while Korosensei and Karasuma find they cannot overrule him.

Seizing his chance to topple Karasuma, Takaoka stages a challenge: a single student must fight him with a real knife while he stands unarmed, with his authority absolute if the student loses. Karasuma picks Nagisa, trusting the boy's latent instinct. Takaoka expects hesitation, but Nagisa closes in as calmly as if walking to school, slips behind him, feints a throat slash, and pins the paralyzed instructor with the blade at his neck. The class realizes Nagisa is a natural-born killer.

A furious Takaoka lunges for a rematch, only for Karasuma to block the punch, and Chairman Asano then arrives to dismiss Takaoka for ruling through fear, reminding him the school is not the Ministry of Defense. The class celebrates having Karasuma back as their teacher.

The episode adapts Chapters 38 through 42. In the original Japanese, Takaoka storms off cursing, while the dub shows him leaving in tears. The manga's images of a muscled Nagisa and Kayano and the teachers' comic ulterior motives are cut, and an added line has Irina react to Takebayashi's answer. It first aired in Japan on April 17, 2015.
