Ado and KUROMI have teamed up for their first collaboration, "DND feat. KUROMI," which will be released digitally on September 25.

The collaboration came about after KUROMI reached out to Ado with an offer to work together. KUROMI made her major-label debut through TOY'S FACTORY in October 2025 and has since expanded her music activities as part of her ongoing "KUROMIfy the World" project.

"DND" stands for "Do Not Disturb." The upbeat track carries a message about ignoring outside noise and other people's expectations while confidently pursuing your own path. The song also highlights the back-and-forth between KUROMI and Ado's powerful vocals.

KUROMI expressed her excitement about working with Ado, saying, "I'm so happy that I got to sing such a cool song with Ado!" She added, "This song is basically saying, 'Don't get in our way!' No one can stop me from following my path, and no one can stop you from following yours!"

Ado commented, "I got to sing together with KUROMI! With a powerful beat and the message 'mute the noise,' KUROMI and I are ready to take it on together."
