Affiliate Marketing Secrets

Theres this manga i read on ‘Mangareader’ about a girl who gets recruited by this secret stock market club at school,
and she has a good eye for picking out items that can sell for big. For instance, when a guy hid some diamonds in a picture frame in his room full of other expensive things, she ended up picking the pic frame.
Please, i forgot what this manga is called, i need help!

A few months ago I read a story about a girl who finds the secret hideout of some club that was famous for producing successful stoker brokers/business people and its pretty much all about making money? The girl has some kind of technique where she is able to find all the items of value wherever she goes i.e. she goes to the flea market and comes back with what looks like junk, but is actually a valuable 15th century statue etc. etc. There is also a popular boy who has heard of the secret club and wants to get in, and eventually uses the girl to into and stay in the club, because he knows she likes him.

I started thinking about ideas for a book, I have written books before, but I was thinking more of a futuristic fantasy setting that would look really good in a manga, but I can’t draw for **** and I am thinking of just writing it as a book. Would that type of style of book be popular in the American market (No pictures, just words). The book would be about a boy who finds a magic pair of headphones, that he uses to help save either his world or another, and discovers the secrets of the headphones throughout the story.

I can draw , but my imagination sucks pretty much . ><
Well I thought of something like a girl named Anastasia Crespelle / Lemaitre and she's being captured in the Labyrinth in a church of a high school in Japan . The Labyrinth is based on the third level of the church which is out of bounds to people . Okay maybe not neccessarily out of bounds , but there's been this rumour that there's a ghost on the third level and intruders would be found missing . ( Maybe examples of intruders and real cause of getting missing ? )
But so ! There's this guy named Kaito and he's a freshman in that school . He can be a delinquent or a nice guy , it depends . He ventures into the third level of the church without knowing of the ' curse ' or rumour and sees Anastasia .
He then returns to the third level almost every single day for lunch ( as he has few / no friends ) and eventually gets to know Anastasia . She is a intelligent person , who can ' read ' minds from people's actions and the way they talk .
PROBLEM :
1. Why did Anastasia get captured and sent to the church in Japan ? ( She's some rich aristocrat's daughter by the way ) Is she a pawn or a traded object and affiliated with the school's heads ?
2. Very very important . How should this story continue ? Mystery ( of the school ) ? Or what ? It's going to end by having World War II and she getting reunited with Kaito after the war . How are they going to get separated ?
Best answer gets 10 points . Please help !!
Thank you ! (:
