In each episode of Ojamajo Doremi: Heartwarming Theater, viewers will meet Ayumi, an original character who shares meaningful moments with Doremi and her friends. These heartwarming interactions are a beloved aspect of the Ojamajo Doremi series and are a common thread throughout this spin-off. Created specifically for the Ojamajo Doremi 20th Anniversary Thanks Festival crowdfunding campaign in 2020, this Flash animation consists of five episodes and is based on the Ojamajo Doremi Story Picture Book: The Best Present. Available exclusively to Camp-fire crowdfunding backers on Blu-ray, the mini-series was distributed in early March 2021.
