Luka Ca (Caルカ) is made by 3DPV artist Deino and converted into PMD format by Hinoi. It is compiled with Teto and Rin.
Despite the file being named Caルカ, the name displayed when loaded in MMD reads "Ca初音ミクver2.2" instead.
One of the textures has text that reads "LuKarune," the portmanteau of Luka's name and Calne's romanization.
The model has various expressions that alter its appearance. Some expressions can hide the shoes and stockings, revealing bare feet, or hide the sleeves, revealing the arms. One expression can close the shirt so that her chest does not show.
