Santa Company is an original work brought to life by Kenji Itoso. A short animation was released in 2014 after a successful crowdfunding campaign, followed by a feature-length version released in Japan in 2019. This work is a spin-off featuring some of the same characters. Upon their visit to a tropical island just below the equator, Mint and co. from Santa Company find themselves confronted with a mountain of ocean debris. Small acts of carelessness upon carelessness have, quite literally, piled up into a big problem—just what have Mint and the others gotten themselves into...? A splendid, yet strange, secret Christmas story.
During the late Tokugawa period, tensions between the bakufu and Chōshū clan are rising due to arguments over how to deal with foreigners in Japan. However, unlike the rest of the Chōshū clan members, Touma Kusaka wants Japan to develop good relations with foreign nations. To achieve this, he attempts to learn English behind his clan's back. A man named Keiichirou Akizuki decides to become Kusaka's teacher, but their relationship soon grows into something stronger, despite the fact that Akizuki works for Kusaka's clan's enemy, the Tokugawa bakufu.
