Beryl lives in a world full of toys. But these aren't your ordinary toys--they're mechanical marvels that almost seem alive! And at the slightest touch, these toys "catalyze," that is, they merge with their owner and give them special abilities. But not Beryl. She's a Neon Knight, and Neon Knights can't catalyze. Beryl does have a special ability that no one knows about--she's an inventor who can turn a broken toy into an amazing, new creation. When a powerful Oxygen Knight named Coro discovers Beryl's secret workshop, she wants in on the fun. But can a Neon Knight and an Oxygen Knight ever get along?

"...based on an original concept by Boya Sun."
