A collaboration campaign between the movie version of ``The Irregular at Magic High School: Yotsuba Inheritance'' and the cities of Kanagawa and Yokohama will be held from May 8th to 24th, the first day of release.

The city of Yokohama was once the setting for "The Irregular at Magic High School." As part of the campaign, a digital stamp rally ``The Irregular at Magic High School ~Yokohama Walk Edition~'' will be held in the Yokohama waterfront area. Depending on the number of stamps you collect, you will receive smartphone wallpapers and original novelty items. Also, at the stamp point, there will be a photo spot with audio of Tatsuya Shiba and Miyuki, and AR photo frames will be distributed.
Yokohama Marine Tower will be lit up in the image of the movie version from May 17th to May 24th. The lights are turned on for 5 minutes each, every 30 minutes between 7:00 PM and 9:35 PM, and at the end of the final episode at 9:30 PM, you can enjoy a searchlight display. Furthermore, from 7pm on May 16th, a 5-minute collaboration fireworks display centered on the image colors of the movie version will be launched at Yokohama Night Flowers x GREEN x EXPO 2027, which will decorate the night at Yokohama Port.
