Bards and Magicians

Are you talking about me? My name is Mostema and I am a detective. Looking at your expression, I know that you have the wrong person, right? Ah! Isn't it? Are you attracted by my temperament? Um, don't get so close to me! Speak well. Have you heard of me? Known as the silver-haired fallen angel? It seems that some operators in the Guards Bureau call me that, but I still like my other name, "Trouble". After all, my card spirit is a magician. Okay, I still have some cases to deal with, what? What is the case? Sorry, no comment, unless... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
