Regulus Corneas is the Sin Archbishop of Greed in Re:Zero, a villain known for his arrogance and for claiming many women as his wives. That extreme, possessive attitude made him a frequent target of fan jokes and short-form edits, where his name alone can signal entitlement and comic villainy. The Regulus Esposa clip circulates in that fan-edit space, pairing the character with the Spanish word for wife to underline the joke. It stays useful because it delivers the reference in seconds, without needing a longer scene or explanation.
