A single wrong quest leaves a veteran hunter stranded in another world as Celia, a silver-haired witch with an unusual gift: she can rent out powerful skills in exchange for a portion of her clients' future growth.

It's the perfect business for someone who wants an easy life.

Unfortunately, every customer leaves convinced they've met an unfathomable mastermind. A careless suggestion becomes life-changing guidance. A convenient transaction is mistaken for selfless salvation. As one impossible miracle follows another, Celia's tiny shop earns a reputation feared across the continent, while its owner wonders why relaxing with snacks and the internet has become so difficult.
