Ado x KUROMI Announcement and Visuals

KUROMI Was the One Who Invited Ado

The collaboration began with KUROMI.

Sanrio explains that KUROMI has been expanding her music activities through the World Kuromification Project, using music to bring KUROMI MIND to a wider audience. As those activities grew, KUROMI wanted to make people happy through singing and create excitement on a global scale.

That ambition led KUROMI to send a direct collaboration offer to Ado.

Sanrio even published the letter addressed to Ado as part of the announcement materials, giving the project a clear story beyond a simple label-arranged pairing.

Ado later acknowledged receiving the letter and described herself as joining KUROMI's wider World Kuromification effort through the new song.

DND Stands for Do Not Disturb

The title “DND” stands for “Do Not Disturb.”

The song focuses on tuning out outside noise—including opinions and values that attempt to dictate how someone should live—and continuing toward one's dreams without giving up individual identity.

Sanrio describes it as a confident and positive song of self-affirmation.

The official material further explains that the lyrics push back against imposed ideas of what is “normal” and labels that do not fit the person receiving them. KUROMI and Ado deliver that message through two forceful vocal personalities.

That concept also fits KUROMI's established music identity, which frequently emphasizes expressing yourself without being constrained by other people's expectations.

Asteroid Music Team Created the Song for the Pair

Ado says Asteroid Music Team wrote the track specifically for her collaboration with KUROMI.

Sanrio's official credits list Kanata Okajima and monii for the lyrics.

The music was composed by Johnny R, monii, Ari and KIRA, with Ari, KIRA, monii and Johnny R handling the arrangement.

Universal Music is responsible for digital distribution.

That makes DND feat. KUROMI an original collaboration track rather than a remix or rearrangement of an existing Ado or KUROMI song.

Ado describes the song as carrying a fierce beat, while the official announcement highlights the powerful vocal exchange between the two performers as one of its defining elements.

The Collaboration Visual Connects Both Identities

Sanrio also released an official Ado × KUROMI collaboration visual alongside the song announcement.

Rather than simply placing both artists in one image, Ado's design incorporates elements directly associated with KUROMI.

Ado appears with twin-tails designed to visually echo KUROMI's signature black hood, creating a shared visual language while preserving the identity of each performer.

Sanrio describes the artwork as blending the distinct personalities of Ado and KUROMI.

The announcement materials also include KUROMI's invitation letter to Ado, reinforcing the story of how their first collaboration came together.

KUROMI Continues Expanding as a Music Artist

DND feat. KUROMI arrives roughly one year after a major new phase in KUROMI's music activities began.

KUROMI made her major debut through TOY'S FACTORY in October 2025, releasing her first EP, KUROMI IN MY HEAD.

That year also included a free live performance at Kabukicho Cine City Square and KUROMI's first music-festival appearance at COUNTDOWN JAPAN 25/26.

In 2026, the project continued with KUROMI's first Zepp battle tour across Tokyo, Nagoya and Osaka, followed by her second EP HYPER KUROMISM in June.

The Ado collaboration now becomes KUROMI's September 2026 release and connects her music project with a singer whose own activities have expanded internationally.

Ado completed a 33-city world tour beginning in 2025 and performed at Nissan Stadium in July 2026, bringing two increasingly global-facing music projects together on one track.

Why This Matters

1) KUROMI is participating as an artist, not just a character

This is not simply merchandise or promotional artwork. KUROMI performs alongside Ado on an original song.

2) The song's message closely matches KUROMI's identity

Do Not Disturb, rejecting unwanted labels and moving forward on your own terms closely align with the KUROMI MIND behind her music activities.

3) Ado and KUROMI bring different but equally forceful vocal identities

The official announcement specifically points to their vocal interplay as one of the central attractions of DND feat. KUROMI.

4) The collaboration has a clear origin story

KUROMI's invitation and published letter give the project its own narrative instead of presenting it simply as two names paired for a single.
