Top 10 Mystery Manga of 1999
1. 20th Century Boys
Humanity, having faced extinction at the end of the 20th century, would not have entered the new millennium if it weren't for them. In 1969, during their youth, they created a symbol. In 1997, as the coming disaster slowly starts to unfold, that symbol returns. This is the story of a group of boys who try to save the world.
For Kenji, a simple convenience store manager who once dreamed of becoming a rock 'n' roll musician, a host of memories from his past come rushing back when one of his childhood friends mysteriously commits suicide. Could this new death be related to the rise of a bizarre new cult that's been implicated in several other murders and disappearances? Determined to dig deeper, Kenji reunites with some of his old buddies in the hope of learning the truth behind it all.
2. Get Backers: Dakkanya
Blonde, hip, pragmatic and cool, Ginji Amano has the power to generate currents with his body like an electric eel. Brunette, equally hip, bespectacled and rambunctious, Ban Mido has the mystically mysterious 'Evil Eye,' the power to create illusions in the minds of his foes. Together, they are the GetBackers, the best retrieval team in the world. They can get back anything taken from clients, and their success rate is (almost) 100%! However, first they have to get some clients--and soon--or this spry detective duo will starve on the streets!

6. Boogiepop Dual
When a female student is abducted and on the verge of being raped, Boogiepop rushes onto the scene just in time to save the day. But Boogiepop's new male alter-ego, Akimizuki Takaya, finds himself in the middle of a crime wave with ties going back to the previous owner of the Boogiepop mantle.
A girl who has the ability to watch the spirits of the death, that has a very important secret in his memory, that unfortunately she lost after escaping from a mental institution. This manga is a sequel of the PSX game of the same name: Koudelka.
8. Kagome Kagome
Takeuchi Masami has been kicked out of his house by his uncle after the death of his father (he seems to take it in stride, but the reader is probably correct in assuming that there is a mystery here, and almost certainly a sinister one). The meager allowance his uncle sends him is hardly enough to find a decent place to live, so at the beginning of the story we find him shacking up at his school, while his cute classmate Kagome Nishino (on whom he has a big crush, although it is not clear as yet to what extent she corresponds him) is trying to help him find an apartment.
As it turns out, she has just found the perfect one, she says, and whisks Takeuchi to a bare, unfurnished place and talks him into moving in right away -- in fact, spending that same night there, alone, and without even a futon to lie on. It turns out that she has an ulterior motive: she is heavily into the supernatural, having just formed a "paranormal research club" at their school, and the reason the apartment is so cheap is because it is said to be haunted, something she conveniently does not mention to Takeuchi, who almost dies of fright that night when all sorts of spooky things begin to happen all around him.
The following morning, at school, Kagome and a teacher who seems to be helping with the "supernatural club" decide that the thing is serious and try to enlist the help of another student, Kagome Kusaka, who, unlike the first Kagome, actually has psychic powers (being descended from a long line of priestesses), but who, also unlike the first Kagome, would rather do almost anything else, and has in fact consistently refused to join the club. On meeting Takeuchi, however, she changes her mind in a hurry, because, as she later explains to him, "there is something special about him": she takes an instant liking to him, and feels that he's the one who can rescue her from the "curse" of her powers (how, you -- and Takeuchi -- may ask? Well, it seems that a priestess must be a virgin...).
9. Shoujo Tantei: Kaneda Hajime no Jikenbo
Kaneda Hajime is a detective, but only during the hours of the Detective Club, part of her extra-curricular activities! If a murder takes longer to solve, it's simply got to wait until the next round of club activities.
