Summary
Douma is an idol, womaniser and overall not a great person. Living in the modern era, he often uses his fame to live the life of a massive playboy.
Karma finally catches up to him when Douma is teleported inside a chinese romance novel as a female concubine. Not only does he experience firsthand the struggles and prejudice women face, but also has to navigate court politics, assassinations and serve as a consort for the four princes ruling the kingdom.
Douma knows how the story will end. That out of the four princes, three will die. Including the female lead. He must prevent this ending from happening at all costs and return to the real world.
The problem is that Douma has only read halfway through, and doesn’t know which of the four princes is the true villain. But Douma suspects the eldest prince, Prince Kokushibo, is the culprit. He puts his idol skills to use, attempting to get closer to the prince using his captivating performances and charm. But as the two grow closer, the two develop a romance both dangerous and forbidden.
[based on mr queen & legend of zhen huan]

Twisted Wonderland x Akaza reader
Akaza, known as (Y/N) (L/N) in her previous life, is sent out to obtain the blue spider lily by the order of Muzan. After gaining no new information she is transported to the world of Twisted Wonderland. As her memory becomes clearer and she recalls her life as a human she gets closer to her love. Her resurfacing memories do not stop her hunger for flesh and her deep hatred of the weak.
How will Nightraven College keep a blood thirsty demon from destroying the world? Will (Y/N) find Koyuki again?WARNING: this is a Demon Slayer crossover featuring a DEMON main character, there will be descriptions of blood, mild swearing, might MIGHT have some suggestive content (I don't know at the moment but I'll update this when I decide to add this or not), cannibalism (idk if it counts when it's a demon but there is eating of humans in this book), death, and torture. Reader discretion is advised.
I do not own Twisted Wonderland nor do I own Demon Slayer. Any artwork used on the cover and the chapters of this story is art that I made. Also this is cross-posted on Wattpad under the same username.

Summary
Hakuji and Akaza are not one and the same—they are twins, adopted sons of Keizou. Hakuji is engaged to Koyuki, and all he wants is a quiet life of peace. Akaza, loud and quarrelsome, only feels alive when he’s fighting.
At the rival kenjutsu dojo, a new student has arrived: Rengoku Kyojurou, who trains tirelessly in hopes of making his family proud.
Their paths should never cross, but they do, and their forbidden love begins.
Fate, however, is not always gentle. What begins in one lifetime may end too soon… and yet, sometimes, the heart remembers.

Sanemi/Demon! Reader- modern Au
Ever since Kimetsu University began accepting demons as students, they made demon/human history a requirement for all attending students. Meaning if you wanted to graduate, you had to take the class. A human and a demon are paired up as partners for the whole year. And they have to work on everything together. It's an effort on the University's part to strengthen and foster demon and human relations.
Sanemi is in his 4th year at Kimestu University, and he's put off taking it, no he's dreaded taking it since he started. Demons are violent, aggressive, for fucks sake they used to eat people! But the Univeristy's rules are firm. If he wants to graduate, he's gonna have to take the class.
Strangers to (mild) enemies to friends to lovers.
