Synopsis
One day, I found an app called [NTR Sensor] on my phone.
It was an app that exerted powers that would be impossible in reality,
It reacted to the scene of cuckoldry and told me where it was happening.
It also gave me the magical power to fight them off…..so I made up my mind.
NTR is something that is only allowed in the world of manga and should not be in reality.
I will exterminate all NTR ! !
That’s what I thought, but then I found myself becoming friends with the girls I saved !?
And now they have turned into Yandere ! How did that happen !?
