A villainous girl created by paranoia

First of all, I am not a kind, gentle, and coquettish girl; I am a bad woman who is more inhuman than a demon.
My life was originally empty and dull, until I encountered that death game.
I was very interested in death games and players, so I tried to become a death game player.
I desperately crave madness and death.

Finally, you need to carefully consider whether you should open this book.
