This Osomatsu-san Gocha Collection figure features Matsuno Choromatsu in a pink variant from the Pokasuka Matsu line. The chibi style emphasizes a large head and a compact body to capture Choromatsu's cautious, self-conscious charm. Painted in a soft pink palette with darker accents on the hair and uniform, the figure wears Choromatsu's school jacket and tie in a simplified, toy-like silhouette that exaggerates his earnest expression. Subtle shading highlights the folds of the blazer and the creases of his small boots. The finish is glossy, giving the piece a playful, collectible look, and it sits on a small display stand to stabilize the pose. Overall build is compact for shelf display, with clean lines and bright, appealing colors typical of the Gocha Collection.

Matsuno Choromatsu is the self-described level-headed elder of the Matsuno brothers, often trying to present a perfect, responsible image even as chaos erupts around him. In Osomatsu-san, he is quick to adopt logical plans, organize activities, and lecture his brothers on proper behavior, though his schemes frequently backfire in humorous ways. He values tradition and social appearances, sometimes clinging to routines and outward success while secretly grappling with his own insecurities. His interactions with Osomatsu, Karamatsu, Ichimatsu, Jyushimatsu, and Todomatsu reveal a mix of rivalry, affection, and comic misunderstandings, making Choromatsu a relatable foil and a steady anchor amid the show's rapid gags.
