by Johnny Yong Bosch. In the English dub of the Clear Card arc, Eriol is voiced by Micah Solusod. Spinel Sun is the cat-like magical guardian created by Eriol Hiiragizawa. The counterpart to Clow Reed's original guardian Cerberus. Spinel Sun's true form is a butterfly-winged black panther with cat-like ears and ruffs of fur on the side of his head, while his false form is similar to a small winged cat with the same wing type as his true form. Nicknamed Suppi by Ruby Moon, Spinel Sun spends most of his time reading and projects a calm demeanor. Ruby Moon often teases him that he needs to have more fun. During the series, he mostly remains out of sight of the main characters, except when he once runs into Cerberus in his false form (though this encounter is exclusive to the anime).

Cerberus does not learn his true identity until just before the final battle when 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 him. In the anime adaptation, he is voiced by Katsuyuki Konishi in his true form, and by Yumi Tōma in his false form. In the second Cardcaptor Sakura movie, his false form briefly appears and is voiced by Philece Sampler. In the English adaptation Cardcaptors, his name is changed to Spinner Sun and both forms are voiced by Colin Murdock. In the Clear Card arc, Spinel's false form is voiced by Apphia Yu.

Her true form resembles a human-sized fairy that performs ruby-based attacks. Ruby Moon is sexless / non-binary and has no biological sex, but prefers feminine pronouns; her "human sex" is unspecified, though Akizuki has stated a preference for women's clothing and enjoys "being cute". Unlike the Yue/Yukito relationship,
