Prolog

Aoi Natsuki, 18 years old. I'm a high school student in Tokyo that I'm used to and have a hobby of reading novels. But that changed since the fire nation attacked.

"Stupid NTR writer, how can there be such a stupid woman?" I asked while angry with the NTR genre novel that I read because the cover was interesting.

"I swear if I become the MC, I will definitely beat up those bastards and bitches" while clenching my fists tightly.

[Congratulations, you got the Anti-NTR System]

[Because the host is a qualified person, the system is created to meet the host's expectations]

[Your task is to destroy the infidelity and betrayal by the Heroine by rough and gentle means]

"What?"

"System can I ask you something" I tried to ask the system like the protagonist did when he received the system.

[Please ask any host]

"Please briefly explain what happened and why?" I asked the system.

Then the system replied,

[The host is chosen to eradicate the evil called infidelity and betrayal, the reason is that there is such a strong emotion from the host to destroy infidelity. Therefore I was assigned to help the host finish off the 'crime'. The system will help the host eradicate crime with various features available in the shop contained in the system with various items and skills that can be exchanged for points. Points are earned by helping cheating victims get a good ending story or preventing characters from being cheated on]

[Congratulations the host got the system, and got 500 points!]

[The host will get starting points to buy something in the shop that can help the host's mission]

I thought for a moment from the notification on the screen. I'm a person who hates infidelity and betrayal for whatever reason, so this system is a blessing for someone like me.

Despite all the complexities of dealing with other people's relationships, this system will help me reach the pinnacle of life.
