Calne ca by tetsuok9999 d5nphfz-pre.jpg

Calne Ca (骸音シーエ Karune Shii-e) is viewed as a derivative of Hatsune Miku, she was created by the 3D animator Deino. The term "Derivative" is used here to describe a fanmade Vocaloid character that is based on an already existing character.

History & Concept

-About the difference between Ca and Calne Ca-
They are the same machine character. The name Calne Ca is used when Ca is in Vocaloid character cosplay.

— Deino's comment

A Deino's original character that has lead to some confusion about her concept. Deino explains on his homepage that Ca, only in Miku cosplay, is called Calne Ca. The bug on her head is also known to be her best friend. Her first apparition was in the lyric-less music video "Machine Muzik" and since then appeared in several PVs.


Her name comes from kara (骸) and ne (音), as well as CA (シーエ), the chemical symbol of calcium. This is due to Calne Ca being a mechanized skeleton with a skin or casing in the shape of Miku.


Calne Ca is basically just a sort of casing in the shape of Miku for the mechanized skeleton Ca (Shii-e).
