This is a world where high technology and magic coexist, and humans and supernatural creatures coexist.
Yu Lien is just an ordinary person, nothing special. As the eldest daughter in the family, she inherits the cake shop.
Ordinary life is broken by a sudden crisis.
A monster appears in the castle on the mountain, powerful, mysterious and terrifying. It is rumored that he has the darkest power and will destroy the world in the future.
Countless magicians were defeated by him, and the troops who tried to capture him failed.
Yu Lien broke into the castle alone and saw a pair of arrogant and contemptuous eyes.
In the darkness, she signed a contract to capture the monster - she needed to find the monster's most cherished treasure and take it away.
World 1: Cursed Monster × Chief Magician
The black mist in the transparent culture tank is the most mysterious monster in the magic academy, and it has been sleeping for a hundred years.
No one knew that this monster had already woken up and was targeting the kingdom's chief magician.
In the bedroom, Yu Lien was sleeping without any precautions. The black mist condensed into a human form, and blood-red eyes peered at her day and night.
"Is that feeling of emptiness in your stomach due to hunger... Or curiosity?"
World 2: Variety Experiment × Princess
The experimental subject has not yet learned how to control his body, and he always becomes weird, ranging from furniture to animals, as well as the comic characters that Yu Lien just finished reading...
Yu Lien returned to the bedroom and saw a slime lying on her bed, with slime dripping onto the floor. He tried his best to hide under the blanket, refusing to let her see, but he couldn't help but stretched out his transparent tentacles and wrapped them around her ankles.
"Are you disgusted with these looks... Don't say disgust."
World 3: A mermaid who sings out of tune × a genius marine biologist
The mermaid has a pair of blue eyes, like the deep sea, which makes people unable to resist exploring. He is the last mermaid in the world, proud and lonely, and no one has heard his singing.
Except for the young marine biologist.
But the mermaid's song not only represents heartbeat, but also represents danger.
"Don't break free from the chains and stay here forever, okay? Your research subject is me, why are you staring at others?"
World 4: Acting Elf × Rich Businessman
Although he is in a chaotic and cruel auction house and is wrapped in heavy chains, the elf in the cage still has a cold temperament and is sacred and untarnished.
The first thing he saw was Yu Lien in the seat.
"What do you want? I'm willing to give you everything except the power of monsters."
World 5: Omnics × Villagers of Primitive Village
The omnics who have awakened their emotions do not belong to humans and are abandoned by the omnics. He longed to have a beating heart like a human being.
Later he was finally fitted with a mechanical heart.
But when the village faces danger, the proud monster lowers his head and is willing to give all his strength... And heart.
"I only allow her to hurt me and I am willing to give my heart to her."
Purpose: Break the prison of fate
