CozmossE is a unit of Nico Nico Douga odorite formed to go on American tours.[1] Rather than posting to Nico Nico Douga, they solely post to an English YouTube channel. CozmossE mainly uploads solo multi-cam freestyling videos or fun videos (with English subtitles). Such "fun" videos usually feature the members playing games, being interviewed, hanging out behind the scenes, or taking turns in challenges (such as the Oreo challenge) and are aimed at allowing viewers to get to know the dancers.

CozmossE is owned by the company Seeking Expressions, which is managed by Sumer.

Originally an all male unit, Micchara and Etero joined in 2014 as the first female members.[2]

CozmossE has membership to Dance Masters United, a YouTube collaboration community founded by CosStarDance.
