Time for Training

Inside a government meeting, the prime minister, Takanojo Migitsuma, fumes that nobody has managed to kill Korosensei in three months. A chief raises a plan drafted by someone in the Information Bureau, a scheme set against Tadaomi Karasuma's approach. Out on the field, Karasuma puts the students through blade testing while mentally drafting a progress report. He rates Yuma Isogai and Hiroto Maehara a sharp pairing with quick reflexes, then sizes up Karma Akabane as idle yet dangerously mischievous, doubtful the boy will land the humiliating blow he is angling for. Among the girls he singles out Hinata Okano, a former gymnast who moves unpredictably, and Meg Kataoka, whose drive and frame rival a boy's, marking both as strong at close range.

When his thoughts drift toward Korosensei as the ideal teacher no one should harm, he discovers the creature whispering those very words into his ear and shoos him off. He notes the rough trio of Ryoma Terasaka, Taisei Yoshida, and Takuya Muramatsu as unmotivated but well-built, and concludes the class is improving at a remarkable clip even if few individuals stand out. That judgment is interrupted when a snake coils around his throat. He instinctively hurls it away, only to find it is Nagisa Shiota, and he apologizes for the force. Sugino chuckles that Nagisa simply was not paying attention, while Karasuma files the boy away as nimble and mild, unremarkable apart from the eerie presence he just felt.

With Korosensei having finished a sand model of the Taj Mahal, Karasuma ends the session. Kurahashi invites him to join the class for afternoon tea, but he declines, citing an expected message from the Ministry of Defense, and heads back inside. The students read his distance as a wall he keeps between himself and his own life, though Korosensei defends him as a genuinely good teacher rather than a mere agent. A flashback shows Karasuma's chief acknowledging his elite record in the airborne forces and in undercover work, yet insisting he cannot finish Korosensei alone without leaning on his secret weapon, the students themselves. The chief announces that a new arrival is on the way.

Back in the present, that arrival opens the door: Akira Takaoka of the Ministry of Defense's Special Services Division, loaded with boxes and bags. He drops his cargo on the field and introduces himself with booming enthusiasm, and the students discover the containers are stuffed with pastries and drinks. When Isogai questions the generosity, Takaoka waves it off, urging everyone not to treat him as a trap and insisting food tastes best shared. He hands Korosensei a slice of cake while joking about killing him, and the class quickly warms to him as a more fatherly figure than Karasuma.

As Korosensei frantically devours the treats in a corner, Karasuma's fellow agent delivers the chief's instruction: Karasuma is to concentrate solely on supporting the students from the outside, while Takaoka assumes their training. Left stunned, Karasuma hears the agent voice her own worry for the class, branding the cheerful new man a dangerous deviant. The chapter, whose Japanese title reads Kunren no Jikan, was published on April 8, 2013 in issue 19, ran twenty pages, and was adapted in the anime as part of Episode 13, Talent Time.
