A kid stays awake on Christmas Eve convinced he'll prove Santa is real to his friends who've stopped believing. The OVA doesn't mock that stubbornness or rush past it, it sits with the specific loneliness of being the last one still willing to believe. By the end, it's not about catching Santa. It's about what you're actually trying to hold onto when you're the only one left who still wants to.
On Christmas Eve, a young boy decides to stay up all night with one goal: catch Santa Claus. If he succeeds, he will have proof to show his older friends that Santa is real. This single-episode fantasy OVA from 1989 tells a simple holiday tale built around a child's determination to see the gift-giver with his own eyes. Perfect for anyone who remembers that particular Christmas night when everything felt possible.
