LiSA will sing the theme song "YES" for the upcoming film 'The Irregular at Magic High School: Yotsuba Succession Arc,' set to premiere on May 8.

'The Irregular at Magic High School' follows siblings Tatsuya and Miyuki Shiba at a prestigious magic high school, where Miyuki excels, while Tatsuya is labeled an “Irregular” despite his hidden abilities. In the new film, the story begins when the siblings receive an invitation to a gathering that will determine the next head of the powerful Yotsuba family.

"YES" marks LiSA’s third collaboration with the franchise, following her opening themes for Seasons 1 and 3. She commented, "I sang as if crying out, releasing emotions that had been frozen like ice."

A preview trailer featuring part of the track has been released on YouTube.
