25時、ナイトコードで。: The Virtual J-Pop Phenomenon

25時、ナイトコードで。 is a Japanese virtual music unit originating from the multimedia project "Project SEKAI COLORFUL STAGE! feat. Hatsune Miku." The group, formed in 2020, has achieved significant success within the digital music and rhythm game sphere, with their original songs accumulating tens of millions of streams and views across platforms.

Early career

The unit was conceptually formed in 2020 as part of the launch of the mobile game "Project SEKAI COLORFUL STAGE!" by Sega and Colorful Palette. 25時、ナイトコードで。 represents a group of four high school students who meet online at midnight to create music, a narrative that deeply integrates with their song themes. Their first original songs, including "Jishoumushoku" and "Idol Shinetai," were released directly through the game and associated music platforms, quickly building a dedicated fanbase.

Breakthrough

The group's major breakthrough came with the 2021 release of the song "Usseewa," a cover of Ado's viral hit, which showcased their signature dark electronic pop style to a wider audience. This was followed by the impactful original song "Bocca della Verita" in 2022, which solidified their position. Their first major compilation album, "THE PERFECT PAST," released in 2023, demonstrated their commercial reach within the niche.

Key tracks

Jishoumushoku — This debut original song established the group's core sound of melancholic lyrics set against upbeat electronic production.

Bocca della Verita — A track that became a fan anthem for its intense portrayal of inner conflict and its complex rhythm game chart.

Usseewa — Their powerful cover version introduced the 25時、ナイトコードで。 aesthetic to many listeners outside the core Project SEKAI community.

Their music, while existing primarily in a virtual space, has crossed over through live concerts featuring voice actor performances and dedicated album releases. Collaborations remain within the Project SEKAI ecosystem, often featuring the virtual singer Hatsune Miku, which aligns with their in-story narrative.
