Daoko and trackmaker Tomggg co-wrote the song "Nanairo Colorful" as the theme song for Miraikan's new permanent exhibition "Nanairo Quest"! Tomggg's energetic, experimental, and pop sounds blend perfectly with Daoko's cute and charming voice to create a song with a unique charm. The lyrics, which incorporate the worldview of the exhibition "The Future of Living with Robots," which Daoko herself created, are also noteworthy.
