Founded in May 2009 as a subsidiary of Triple A, the studio was established by Ryosuke Yamada, who served as a production desk at Triple A, Takuya Ono, who oversaw production, and animator Takeshi Oda, with the aim of creating original works for the company.
The name is an abbreviation of "Challenge To Challenge," reflecting the influence of parent company Triple A's corporate philosophy that "without challenge there is no success." Although its business scope included animation planning and production, the studio primarily functioned as a gross contractor for other companies after its founding, mirroring the parent company's approach. Since 2012, it has handled the production of five-minute short animations, such as "Yurumeitsu Kare wa 3D," often in joint productions with other firms. The studio frequently collaborates with production companies and satellite studios, managing numerous gross contracts for satellite productions even after commencing its own production activities. Pursuing the goal of "someday becoming a prime contractor production company," it continued to undertake gross contracts, co-productions, and short animations for other entities. It achieved this objective by independently producing TV animation works. While it has since operated mainly as a prime contractor, it has also continued to accept gross contracts as before.
In February 2022, the studio established a finishing department within the company.
