Mini bio

How it started.

Kuzuha began as an independent VTuber on March 8, 2018, and joined NIJISANJI Gamers that July. Games and singing became the core of the channel. The vampire is the public character: the official talent profile describes a whimsical gamer with a weakness for money.

From covers to original songs.

Cover performances opened another path alongside streaming. Kuzuha released the first original song, “Contrail,” in September 2021 and announced a major-label debut at the birthday event Scarlet Invitation that November. Sweet Bite followed on March 9, 2022.

Two stages to share.

With Kanae, Kuzuha performs as ChroNoiR, a unit formed in 2018 that releases music and hosts the show くろのわーるがなんかやる. Solo music brought an anime credit when “Black Crack” became the opening theme for Netflix’s Good Night World.

Keeping fans close.

After reaching two million YouTube subscribers on June 3, 2025, Kuzuha celebrated with a 3D concert eight days later. In the official interview afterward, Kuzuha explained wanting to share the milestone with viewers and put on the show while that excitement was still fresh.
