Kazuhito Soma was born in Aomori Prefecture, Japan. He has launched a brand that makes wedding rings and engagement rings. Ever since he first saw the aurora, he was wondering if it could be expressed in metal. One day when he researched a miraculous technique that no one could do and experienced many failures and setbacks, inspiration that he had never experienced ran all over his body and made a gradation ring called Aurora. He will never forget the events. He wants to spread it to the world.
