Ado's new song "Yukue Shirezu" has been picked up as the theme song for the movie 'Karada Sagashi' to open in theaters on October 14. This song was written and composed by Sheena Ringo.

Directed by Hasumi Eiichiro, 'Karada Sagashi' is based on a novel of the same title by Welzard that was published on the novel posting site Everystar in 2011. It will star Hashimoto Kanna, Maeda Gordon, Yamamoto Maika, Kamio Fuju, Daigo Kotaro, and Yokota Mayuu. 

On her collaboration with Sheena, Ado commented, "To have a song written by Sheena-san and to be in charge of the theme song for movie 'Karada Sagashi,' I feel very honored to the point where I feel I've run out of lives and that I've used all the luck in this world." Meanwhile, Sheena stated, "When I first listened to Ado-shi's voice, I thought 'what an ideal doraneko (stray cat) voice.' If I heard this 25 years ago before releasing Muzai Moratorium, I probably would've had her sing all of it." 

In addition, Ado and Sheena's collaboration visual has been revealed. It was illustrated by ORIHARA, who is Ado's image director.
