The Rock Star’s headstock is shaped like a curved hook with four curved, pink spikes lining its outer edge. Its neck is thick and light lavender with black edges. The sitar’s body is roughly diamond-shaped, and is predominantly lavender with black edges. Its sides are more ornate and spiked and are pink with black edges. It has three white strings that are anchored to the body by a grey, diamond-shaped piece.
Its name is a reference to rock musicians' use of guitars, which are similar to Demyx's weapon, a sitar.
Rock Star's normal ground combo starts with Demyx performing a 360-degree spinning diagonal slash with the tip of the sitar, followed by the same attack, but in the opposite direction. The combo ends with another 360-degree spinning attack, after which, Demyx strums the sitar, emitting a yellow shockwave which damages any enemies around him. The -Combo can be activated after the first or second attack, and consists of a leap and a series of very fast airborne spinning attacks.
The aerial combo consists of a series of very fast airborne spinning attacks, followed by a downward diagonal slash with the tip of the sitar, and ends with four quick blasts of yellow shockwaves in an outward direction.
