Isekai(?) manga where the female protagonist is taken to a fantasy world while sleeping in her bed

Question

It was a black and white manga. I believe the protagonist had dark hair, but I could be wrong. It was a very darkly drawn manga with horror themes.

In the first chapter the female protagonist is sleeping in her bed and she believes she is dreaming about a fantasy world. Without her knowledge, her bed has done the full bedknobs-and-broomsticks and taken her to a full fantasy world.

When she lands she is attacked by a unicorn, who is promptly cut in half by a character with magical(?) tattoos and also resembles a Shin Megami Tensei Demi Fiend.

To elaborate, I read it a few years ago and it was relatively new at the time. There were, maybe, 15 chapters out. From what I remember she was asleep flying through the skies and what we see is her dream. The bed lands and she wakes up confused and sees a unicorn, which suddenly becomes hostile. it was drawn in decent detail. Then the Demi Fiend lookalike came from nowhere and used his tattoos to cut the unicorn in half. He had the ability to move the tattoos around, change their size and extend them from his body. I also vaguely remember that he was subservient to another being from that realm. It was implied his master wasn't 'good'. I don't remember if there was more before her flying into to other realm, but it was in the first chapter and relatively close, or the actual, opening scene.

Answer 1

This is Curse Blood. There is only one volume - the series was discontinued due to the author's death.

"If your heart is stolen, then we will be trapped in the cycle of reincarnation forever, we will borrow your strength, save us, save Payton." Those were the last words a mysterious woman said to Kyouko in her dreams. When she awoke, Kyouko was already in a fantasy world, surrounded by gigantic beasts, horrible creatures, and a boy named Solomon with strange tattoos all over his body.

The question is an almost-perfect match for the first chapter. A girl wakes up in a strange world while still in her bed,

and thinks she's still dreaming. She is then attacked by a dragon-like creatures (and later a wolf-like creature - the closest I see to a unicorn in the first chapter is the wolf with spikes through its head)

And is protected by a man with strange tattoos all over his body, and can use the tattoos to attack.
