It's not extraordinary, just another story about detectives. However, I started to see some potential when I finished watching all the episodes and realized this was just the beginning of something very special and particular. Maybe watchers wanted her to be extremely intelligent and smart from the start-go and the comedy is silly, like every Japanese anime that we are familiar with, but the butler character seems to be a key point in this and seems to have some mysterious reason as to why he's serving her, maybe to teach her about the profession and of course, make her mature.
