暗殺教室 [Ansatsu Kyōshitsu / Assassination Classroom] #17

Volume 17 of Assassination Classroom presents the series' signature bold minimalism — Koro-sensei's enormous, toothy grin floating against a vivid yellow background, those distinctive droplet shapes scattered around him like a visual signature of his alien energy. Creator Yūsei Matsui's instantly recognizable cover design distills the whole series into one unsettling-yet-cheerful image, the subtitle 「分裂の時間」(Time of Division/Splitting) hinting at something significant stirring within the pages. A sharp addition to any Assassination Classroom collection, this Jump Comics volume captures exactly why Koro-sensei's impossible smile has made such a lasting impression on manga readers.
