Terror strikes, demons revive!

This is hell, the death knell has already sounded.

The demons collapsed the world, and I devoured the evil demons!

The system is activated, devouring hundreds of ghosts and demons!

Ding! "Congratulations to the host. You have devoured the demons and monsters and obtained the Judge's Death Pen, which can reverse the chaos of yin and yang and judge all living things!"

I am in hell on earth, evolving infinitely, tearing apart the dark fog, letting the divine light shine upon the earth, and no longer blurring my eyes!

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.
