Filo

Filo is a character credit associated with Japanese voice actress Rina Hidaka, and the listing is marked as an episode 4 appearance. It is best understood as a cast-linked vocal credit rather than a standalone solo artist entry. For readers searching anime openings, endings, soundtrack credits, and other performance records, the entry helps identify how Filo is credited within a specific production. The character name, the connection to Rina Hidaka, and the episode 4 tag make the credit easier to trace in cast listings and other anime music metadata, especially where clear attribution matters for ending theme credits and related appearances.
