Meowa, whose real name is Ayumu Hikaru, is a famous mystery novelist. His face was never known until his privacy was breached and his face revealed a few times, with his fans only knowing that he was a young man.

One day, Hikaru was on his way home when he was attacked and stabbed by someone. The last thing Hikaru remembered was a shooting star passing over the perpetrator's head. 'A good last view, huh?' he thought, as if laughing at his fate ending this way.

When Hikaru regained consciousness, he found himself not in his original world. As a novelist, he could guess what was happening to him now – isekai – but it wasn't a good thing, and he realized he was in bigger trouble.

"HOW DID I END UP IN MY OWN NOVEL!?"

What kind of book is he in that he's so panicked and scared? Who was the assailant, and what kind of adventure will Hikaru experience? Can he discover the truth and start his new life in his own imaginative world without any problems?
