A boy is transformed into a girl by the power of a system, embarking on a path unlike any other. She will fight to the death with people and those who claim to be from outside the world, protecting this world full of memories.

After getting killed by my yandere little sister, I am reborn in an RPG world. Moreover, it is the RPG world I programmed and wrote the script for. As the author of the game, I must definitely be omniscient and omnipotent… but wait? Why am I born as a baby girl? Hey, that’s not how the script goes! Is this a mistake? I am a man!
