She introduced herself as adventurer 『Aria』, gradually mastered multiple weapons and magic, and grew to become the 「Ash Crowned Princess of Slaughter」! But, by accepting a request to guard the “villainess”, before she realized it she got dragged into the stage where nobles quarreled against each other――？

Create weapon! Train your body!

Survive the fighting against powerful enemies and smash apart the otome game!

A sublime and exhilarating other world battle fantasy with charming fighting heroine!

Ancient existences wake up in the abyss, demons whisper in people’s ears, unknown horrors erode the spirit, and madness breeds in the darkness of people’s hearts.

But it is not only darkness that descends on this world.

There are heavily armed dark knights walking in the dark to judge crimes; tight-fitting supernatural beings wandering between buildings to act as friendly neighbors; The impossible god on earth, the “S” symbolizing hope shines like the sun on his chest…

Once transmigrated into a cannon fodder villain with the same name as himself, Wu You said that he had a headache.
The original protagonist did everything in his power. Not only did he offend the protagonist, but he also offended Zhao Qingzi, the biggest villain in the book.
The villain, Zhao Qingzi, has disabled legs, is obedient and gentle in front of people, kills people without blinking, and has a gloomy and crazy personality.
After the original owner stabbed her with a sword, she said on the surface that there was nothing to blame, and secretly sent someone to stab the original owner into a sieve and throw the corpse into the wilderness.
Wu You looked at his hand holding the sword, and then at Zhao Qingzi, the beautiful villain who was stabbed by him.
When his mind was blank, the voice of the male protagonist questioning him why he did this came, and Wu You suddenly had a flash of inspiration.
Then he looked at Zhao Qingzi with a distraught expression on his face: “Qingzi, why do you always run to others! I love you! Look at me!”
Male protagonist: ? ? ?
Zhao Qingzi: ! ! !
Wu You always thought that this time-travel was a super-difficult survival dungeon. It was not until the end that she realized that the difficulty of this dungeon had been adjusted to be easy from the very beginning.
From the moment she uttered that absurd love, this girl who longed for light gave her sincerity.
Zhao Qingzi said, “I don’t like this world, but I’m happy with you, Ayou.”
Wu You held her hand and smiled sincerely: “Little fool, then I have to pester you every day, lest you still think about those sad things.”
In the end, the lie became the truth, and the two finally got married.

Optimistic and strong, through the book attack × ruthless double-sided villain
