A girl who likes to make stories and belongs to the literary club, Mana Shinoya. One day, Mana finds a notebook with a fine binding.

"I want to write a story suitable for this notebook."

As if guided by the notebook, Mana wrote the story of Lamina, the world of beastmen.

Among the beastmen, there is a clan that is declining to the point where the species cannot survive. To prevent this, the government of Lamina housed the endangered clan in this reserve to protect the species from extinction. In this protected area, where there is no fear of extinction, the beastmen can live in peace as if they were enveloped in their mother's body, as if they were dreaming of slumbering...

When Mana woke up, the world had become a reality and spread out in front of Mana. However, contrary to expectations, the world was not the peaceful world Mana had envisioned.

"Help...! Someone, please help me...! Get me out of here...!"

"The Little Mermaid, I'll give you human legs, and in return, I'll get your beautiful voice."

A phrase from a story I read a long time ago crossed my mind. Wizard Grandma, if you are really in this world, give me sharp claws that tear through walls. Fly and escape, give me strong wings. I don't need a voice. Because my voice is just a sound, and no one listens to me...
