Ojisan and Marshmallow

Ojisan and Marshmallow originated as a web manga series created by the artist Rekomaru Otoi. The work gained significant traction on the platform Pixiv before being adapted into a short-form television anime series by Studio Creators in Pack in early 2016. The story centers on the workplace dynamic between Hige, a middle-aged office worker with an intense obsession with marshmallows, and Wakabayashi, a younger colleague who uses her affection for him to pique his interest.

The animation design focuses on a minimalist, episodic structure that reflects its origins as a digital comic. Creators in Pack emphasized a lighthearted, observational approach to the characters' office life, prioritizing comedic timing and the interplay between the two protagonists over complex visual effects. Upon its release, the series was noted for its brief runtime and its ability to condense the niche, quirky humor of the original manga into a digestable format for a television audience.
