This 1/6 scale Koro-sensei figure stands approximately 450 mm tall and captures the character's unmistakable silhouette: a round, bright-yellow head with a wide, perpetual grin and multiple tentacle-like limbs flowing dynamically around a tailored teacher's suit. The sculpt emphasizes clean lines and playful proportions, with finely defined facial expressions and smooth tentacle articulation that suggest motion. Paintwork uses vibrant yellows and high-contrast black and purple tones for the suit and tie, plus subtle shading to enhance depth. The included base is stable and themed to match classroom elements, completing an eye-catching display-piece for collectors.

Koro-sensei is the central figure of the series 'Ansatsu Kyoushitsu' (Assassination Classroom), portrayed as a highly unusual yet oddly compassionate teacher who instructs a class of underdog students. Once human, he was transformed into a super-powered, tentacled being with incredible speed, regeneration, and intelligence, and he now pledges to teach Class 3-E while a looming assassination deadline drives the plot. Despite his threatening origin and formidable abilities, Koro-sensei develops genuine care for his students, using creative lessons to nurture their talents and confidence. Conflict, humor, and emotional growth intertwine as the class balances assassination attempts with classroom life, revealing themes of redemption, mentorship, and the complexity of what it means to be human.
