Clear Rainbow Purple Lightning is Zuo Ci's primary weapon in the form of a double-head electric guitar.
This guitar can produce very special music waves that surpasses that of most music instruments, such as Xiu's Little Wasp. The waves allow the musician to produce powerful magic atmospheres that are usually beyond his limit, and defeat extremely powerful demons or demonic power-users.
