King & Prince has released a special collaboration video combining their latest theme song "Waltz for Lily" with footage from the upcoming film "Oni no Hanayome" (The Demon's Bride). The video is now available on YouTube.

The film stars King & Prince member Ren Nagase alongside actress Ai Yoshikawa in a dual lead role. Having the group provide the theme song creates an interesting connection, with Nagase both starring in the movie and performing the accompanying track with his bandmates.

"Oni no Hanayome" appears to be a supernatural romance, fitting the dreamy, waltz-like quality suggested by the song title. The collaboration video likely gives fans a preview of how the song will complement the film's emotional moments.

For King & Prince, providing movie theme songs has become a regular part of their activities, allowing them to reach audiences beyond their core fanbase. The group has successfully balanced their idol activities with individual member pursuits like acting, and this project represents another example of that synergy.

The collaboration video serves as promotion for both the film and the song, giving international fans a chance to experience the pairing even if they can't see the movie in theaters. King & Prince continues to expand their musical range with each release, and "Waltz for Lily" suggests they're exploring more mature, cinematic sounds.
