About us


C-CLAYS イメージイラスト

C-CLAYS & K2 SOUND are doujin music circles that produce and publish music related works such as original drama CDs, original music, and arrangements. The circle also makes life-size tapestry as the interest of our representative.

“Let’s make fan projects from our favorite titles!” and that was why the circle was founded. Since then the circle started making arrangements for Touhou Project and Kantai Collection (KanColle) since 2013. Moreover, the circle made its commercial debut in 2010 by composing and arranging the theme song and various background music for the anime OVA “Aki Sora ~Yume no Naka~”.

Thanks to everyone supporting our music and events, C-CLAYS was able to venture into its 10th anniversary in 2014. We would be grateful if you continue enjoying our music ♪
