[Detective Conan] Kudo's Little Sister Is Charming and Dangerous

I'll fill in the blurb later. For now, just a rough idea.

A timid, sickly younger sister, completely unaware of her own beauty x a bunch of people who are enjoying being forced by her?

P.S. The younger sister is seriously ill, and she's really not right in the head. She likes picking people up, especially the types who can't see the light of day. (Including, but not limited to, Gin, Bourbon, and Vermouth...) She judges people by their faces, and she's extremely timid and cowardly! She wants to do bad things but is afraid of getting beaten, so she keeps a low profile. She's completely unaware of her own beauty. She wants to collect beautiful faces as specimens, and enjoys medical dissection, but she's clumsy and secretly a big shot?
