Trailer for the anime film The Deer King reveals the theme song

On the official website for Shika no Ō: Yuna to Yakusoku no Tabi (The Deer King: The Promised Journey With Yuna), the anime film adaptation of Nahoko Uehashi's fantasy novel series Shika no Ō (The Deer King), streaming has begun for a trailer and teaser video for the film. The song "One Reason" featured in the trailer was written by singer-songwriter milét.





The film will open in Japanese theaters on September 10, following a one-year delay and during this year's shortened edition of the Annecy International Animation Film Festival, where it was placed in competition among several entries.

GKIDS describes the film as follows:

In the years following a brutal war, the Empire of Zol now controls the land and citizens of the rivaling Aquafa—except for Aquafa's Fire Horse territory, where wild dogs that once carried the deadly Black Wolf Fever continue to roam freely. When a pack of dogs rushes through a Zol-controlled mine, Van, an enslaved former soldier, and a young girl named Yuna are bitten but manage to escape as the only survivors of the attack. Finally free, Van and Yuna seek a simple, peaceful existence in the countryside. But as the deadly disease begins to spread once more, they find themselves at the crossroads of a conflict far greater than any single nation.
