Cha Kurii is a Japanese manga artist and original creator, known professionally by the name written as 栗井茶 in Japanese. Information on personal background indicates a birth date of August 22, 1983.

Kurii is best known as the creator of the long-running gag comedy series +Tic Elder Sister, also known as Plastic Neesan. The series began serialization in Square Enix’s seinen manga magazine Young Gangan on September 4, 2009, and remained in publication for many years, with its chapters collected into numerous tankōbon volumes. The story follows the members of a high school plastic model-building club, though the narrative focuses primarily on the eccentric personalities and absurd, often raucous, comedic interactions of its characters rather than the hobby itself.

The series was adapted into a twelve-episode original net animation produced by TYO Animations and directed by Tsutomu Mizushima. The anime was released in two parts, with the first five episodes debuting online in 2011 and the remaining episodes released on home video in 2012.

In addition to this flagship work, Kurii launched another comedy manga titled See Only Me Me Me Me Me (Mememememememememe Menhera) in Square Enix’s Young Gangan magazine in November 2016. The story centers on a university freshman whose new girlfriend exhibits intense and obsessive behavior.

Kurii’s artistic identity is strongly tied to gag comedy, characterized by erratic, slapstick humor and a cast of distinctive, often irreverent characters. The creator’s writing style is noted for its efficient use of short formats to deliver humor, relying on well-defined character archetypes and their interactions rather than deep narrative arcs or significant character growth. The work has developed a notable following over its long publication history for its consistent comedic approach and willingness to cross-reference other popular culture.
