Morohoshi Daijirou's take on the Grimm Fairy Tales. Some are relatively straight adaptations while others have a sci-fi, horror, comedy, or mystery-twist.

From Lililicious:

A sci-fi story set in a future where men have died off. Women have been divided into two groups: Adams and Eves. Each has a set role in society. The protagonist, an Adam, has just entered Kingdom Academy. Romantic relationships between Adams are forbidden there, so I'm sure you can all guess where this is going...

From Mangascreener:

Icoro is the princess of a country of eternal night. Her kingdom is surrounded on all sides by huge mountain walls. Snow falls constantly, yet without the warmth of the sun's daylight, it will never melt, only pile up higher and higher. Her people are destined to die out. While she is a member of the ruling royal family, her parents have both disappeared, leaving her alone with her blind younger brother, and crafty politicians hold all the power behind the scenes, leaving her sovereign in name only. Her life has been an endless cycle of hardship, and she has never smiled, not once. In fact, she is missing that part of all humans that knows happiness.

Enter Shiro, a mysterious young boy whose identity is an enigma, even to himself. He is able to forget all but the most vital of information within seconds. All he knows is that he is looking for something called a "Hitogata." After Icoro and Shiro's chance meeting, they end up on a desperate search for the sun that will melt the snow and bring happiness to the kingdom once more.

Will they ever escape the grasp of the corrupt authorities? Will they even recognize what they're looking for, if they come across it? Will this "Hitogata" be the key to finding a sun to save their home? The answers lie ahead.

It's a simple job, getting your blood sucked by Kaya Kiryuuin. Or...is it?

The human race is becoming more and more dependent on increasingly complex technology and machines; machines that inevitably break down. According to those lucky people who work at ATMT, the best job in the world is to be one of those special people who exists between the human world and the cyber world as "therapists", inserting their consciences into the broken machines via a proprietary interface to conduct the repairs. Such a job is not without immense risk and can result in a person being trapped in the device as an annoying, pitiful bug. Amongst the therapists, there exists a chosen few who have additional power and capabilities and who face the greatest risks and dangers - the Automata.
