The female lead (Honoka Saga) is a long lost descendant of the greatest (female) magician in history, a magician who had founded an magical organization centuries (or something like that) ago.

After years of searching, the org. was able to track down our (now Japanese) female lead who turns out to be the descendant/reincarnation of their great (blonde) founder (Rozen Kreuz).

She's broke and orphaned, working hard to earn and get by (in not a dramatic way because she's quite funny) which leads to her believing that the only way to be happy is to have money. (It's one of her quirks which the male lead is constantly trying to literally beat out of her)

The male lead (the name's Hardenburg, Elvin Reiko Hardenburg. Don't wear it out) is handsome, a magician and the new leader of the org. set on finding their org's reincarnation and the magic book their founder had left for her reincarnation.

You think he's going to be some sort of prince-type because of his looks and first encounter (that he's going to be some kind of dog to the female lead, following her around and catching her whenever she falls, wiping her tears,etc) but we turn a few pages and get quite a surprise.(I'd go so far as to call him a really lovable sadist. Really.)

The main antagonists for now, introduced in the first chapter (I'm telling you, the pacing will get you whiplashed like crazy) are from a rival magical org. who also want to get their hands on the magical book. (They're really funny and cute too. When I first saw them, I was thinking that this was going to have a reverse-harem of some sort but their reaction to the female lead was just hilarious)
