The Da Capo's headstock is an “X” shaped like the upper half of the Nobody sigil. It is mostly blue, but the tips of the X are pale yellow. The Sitar's neck is blue and yellow and has ridged, blue edges. The body has a roughly semi-circular shape, and its base is lined by five blue spikes. The upper half of the Sitar's body is predominantly yellow, and the lower half is predominantly blue. The Da Capo has three white strings that are anchored to the lower half of the body.
Musically, Da Capo is a term that means "from the beginning." Variations are Da Capo al fine, meaning "repeat from beginning up to the word 'fine'," and Da Capo al coda, meaning "to play from a sign-specified place in the music to a different ending."
The Da Capo's ground combo starts with a quick leap forwards, thrusting the Sitar diagonally upward, followed by Demyx performing a 360° spinning diagonal slash with the tip of the Sitar. The next move of the combo is a quick thrust of the Sitar diagonally upward, followed by another spinning slash. The combo then ends with a 360° spinning attack, after which, Demyx strums the Sitar, emitting a yellow shockwave which damages any enemies around him.
The aerial combo consists of a downward diagonal slash with the tip of the Sitar, followed by a thrust upward, and ends with a blast of three yellow shockwaves forwards.
