Spinel Sun

スピネル・サン

Spinel Sun is a cat-like magical guardian created by Eriol Hiiragizawa as a counterpart to Clow Reed's original guardian, Cerberus. His true form is a winged black panther, whereas his false form resembles a small winged cat. Nicknamed Suppi by Ruby Moon, Spinel Sun spends most of his time reading and projects a calm demeanor. Ruby Moon often teases him, saying he needs to have more fun. Throughout the series, he mostly remains out of sight of the main characters, except for one instance when he runs into Cerberus in his false form. Fortunately for him, Cerberus does not suspect anything; instead, he declares Spinel Sun a monster and feeds him sweets, not realizing that the sweets would turn Spinel Sun into a hyperactive eating machine. Cerberus does not learn his true identity until just before the final battle, where the two cats face one another. Initially, Spinel Sun appears to have the upper hand; however, Cerberus' greater determination to protect Sakura enables him to defeat Spinel Sun.
