Twenty-One Dawns (Surprise! I Am a Genius Girl at the End of the World!)

Don't Post It Below 9.3. I'm Done with the Slaying of Gods, so I'm Looking for a New Book.

There Aren't Any Good Books to Read Lately.

I want to read a book like "The Empress: The tribe was overthrown by the Empress at the beginning". I want the male protagonist's perspective, not a harem.
