timelesz has released the music video for their new song "Kienai Hanabi." 

Written as the theme song for the animated film 'Kimi to Hanabi to Yakusoku to,' starring Shori Sato, the song reflects on the idea that while fireworks eventually fade, the memories shared with loved ones remain. 

The video follows the group's summer adventures, from running along a riverside and enjoying a barbecue to jumping into a pool together, with the finale featuring a dance performance filmed beneath approximately 500 real fireworks.
