A girl who doesn't believe in fairy tales walks into a fairy tale.
She relies on her fists and brains, not magic. Starting with Cinderella, she will find people in every world who are "unwilling to follow the script" - Sleeping Beauty, Little Red Riding Hood, Snow White, and the Daughter of the Sea.
She would stand side by side with them. Instead of waiting for them.
The hero is not here to save her. He came to break the situation with her. The two of them each carry their own responsibility, and occasionally fight a tough battle back to back. He was arrogant and she spoke little, and each of his blows became more severe than the last.
This is a story about "the princess getting her pen back".
The princess can be seen without wearing glass slippers.
The princess can choose not to wake up.
The princess can wear the red cloak as a battle robe.
The princess doesn't have to go ashore.
The princess does not have to be happy forever, but she can be free forever.
