Actually, I didn't have a grand goal from the beginning. It was just one day when I suddenly thought, "Wouldn't it be fun to combine the mystical elements I like with development?" I've always been interested in topics like data, human psychology, and destiny. But most websites handle such things too 'seriously'. Rather than that kind of atmosphere, I wanted to create a service where people can enjoy it lightly and also reflect on themselves once in a while. That's how the Persona Arcana Calculator came about. This isn't about fortune-telling or prophecies; it's simply an "experiment to interpret the patterns of who I am in another language." People often ask questions like "What kind of person am I?" or "Am I doing well these days?" At such times, I hope this tool can act like a mirror that makes them pause and think for a moment. Technically, it might be a very simple calculator, but I believe it can be a small signal that makes someone's day start fun. That's the reason I keep developing this product.
