The Koro-sensei figure captures the iconic yellow, round head with a wide, perpetual grin, large blue eye detail, and the texture of his smooth, rubbery skin. The sculpt emphasizes the segmented, tentacled silhouette, with subtle shading across the dome and limbs that highlight the character's cheerful yet enigmatic personality. The figure stands in a dynamic upright pose, one arm slightly extended as if greeting students, while a gently sculpted base evokes his classroom environment. The paintwork uses bright lemon-yellow tones accented with orange and pale highlights, and the distinct white shirt and blade hints are rendered with clean edges for a crisp, collectible look.

In the anime and manga, Koro-sensei is a mysterious, extraordinarily powerful teacher who can move at Mach 20 and erase fear with a smile. He promises to grant his students a chance to pass the class by their own methods while secretly offering them the assignment to assassinate him before the graduation date. His playful, quirky demeanor hides a tragic backstory and a relentless desire to teach responsibility, teamwork, and resilience. The figure nods to this dual nature by conveying warmth in the face and a hint of urgency in his posture, inviting fans to explore the paradox of mentor and target.
