Recommended Manga?

Heya all, thought I'd put up a thread for any Manga you want to recommend.

Throw in the title, a little summary (minus spoilers!) and why you like it.

Also thought it might be a good place for anyone who likes a certain Manga title and wants to know of any other similar Manga's out there

I'll start us off
I like DearS, Chobits and such stuff, so if nayone has any recommendations for me that would be great ^^

If you are a fan of Chobits you might also like DearS, which is evry similar to Chobits but completely holds it's own.
I also really like Mark of the Succubus, a three part Manga about a succubus who accidentally puts her mark on a human she loves, meaning she has to kill him. The story involves them trying to find a way to remove the mark. It's really sweet and was the first Manga I ever read

Iv'e just purchased the first volumes of:
Vampire Knights
Demon Diary
Alice 19th
Stray Little Devil

They all look pretty intresting so will get back on them.
Demon Diary has some very soft Yaoi in it, so I know someone who might want to borrow that..... >.>

If you're a fan of Lovecraftian Weird horror done with a Japanese spin, I recommend Junji Ito's Uzumaki; Spiral into Horror and Gyo; the Death Stench Creeps (usually comes with the Enigma of Amigara Fault short story). All truly creepy, weird and unsettling.

Just my kind of manga then! Will have a look into these

ps. Vampire Knights is pretty cool, do love the main female character, nice to see one a little different.

Alice 19th I absolutely love! Will be getting volume 2 very soon me thinks
