The official website for Key and Visual Art's announced on Tuesday that the release date for Kud Wafter will be delayed a full year and is now set for next September. After speaking with J.C.Staff, the staff mentioned that scheduling for the studio and the production team members were too difficult for a September release, given the studio currently has many other anime projects lined up. In order to ensure high-quality animation, they pushed the release back. The official website also announced a change of director from Yoshiki Yamakawa to Kentarou Suzuki, who worked on other anime adaptations of Key's works.

Developed in June 2010, Kud Wafter is the eighth visual novel by Key. A PlayStation Portable version of the visual novel was released in May 2013, followed by a PlayStation Vita version in December 2013. A manga adaptation drawn by Bakutendou was serialized in Dengeki G's magazine between March 2010 and December 2013.
