for context, this short omake is based on a viral topic in the Japanese social media in 2024. People found their pet's real names in the certificates and had been sharing online on the names at birth and their current one. (I saw one user who had a cat currently named Sanuki, got the birth certificate name "Eternity Shines Jet" back then)
