Death Bet: the Life of Chikage

Have you ever heard of Thousand Shadows of Life? In a city full of happiness, there are people seeking death every day. "Don't despair, let's get your life back." There are two places at the negotiating table, one for me and the other for my guests. I have no name, no appearance, just black clothing and a unique mask. No one has ever looked at me, and neither will you. I am who I am. My guest can be anyone. They have a variety of costumes, looks. They are different ages, different skin colors, different souls. The only thing they have in common is their purpose "Revenge!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
