milet's new song "Sunny" has been chosen as the opening theme for the upcoming TV Tokyo anime 'Though I Am an Inept Villainess: Tale of the Butterfly-Rat Body Swap in the Maiden Court,' which premieres on July 12.

Based on the light novel series of the same name, the anime follows Reirin, a beautiful and intelligent court maiden who suddenly swaps bodies with Keigetsu, a woman despised by those around her and known as a villainess. Despite the challenges she faces, Reirin refuses to give up and pushes forward with determination.

"Sunny," which will be released digitally on July 12, was written specifically for the series. milet commented, "The story begins with Reirin and Keigetsu switching places. I'm sure there is a world that only the two of them can see, and I'm very happy to be able to dive into that world with a song called 'Sunny.'"

A clip of the song can be heard in the anime's trailer, which can be seen below.
