Tadayuki Higashimura, having defeated the Demon Lord in another world, successfully returned home.

Immediately upon his return, a notification on his smartphone prompted him to restart a heated online argument with someone he had been feuding with on social media a year prior.

"I have to make this bastard eat his words...!"

As if his prayer (?) had been answered, his Appraisal skill evolved into "Personal Information Disclosure."

A few days later, after thoroughly provoking his opponent with the acquired personal information and even showing up at their home (家凸 – *ie-totsu*), feeling utterly satisfied...

Tadayuki discovered, through the power of "Personal Information Disclosure," the betrayal of the girlfriend who had been his emotional anchor throughout his time in the other world.

What's more, the man she was cheating with was someone he had considered his best friend since childhood.

Not only that, but she was pregnant and was even planning a so-called "brood parasitism" (*takuran*), intending to pass the child off as Tadayuki's.

His life in the other world had been driven by the desire to see his girlfriend again, to survive and return to her.

He had rejected approaches from many women, only to be met with this treatment upon his return.

Tadayuki, who had remained faithful to his girlfriend, now found his spirit consumed by the dark flames of revenge, a reaction to the profound betrayal.

Utilizing the powers he acquired in the other world, he began gathering evidence and preparing to bring about their downfall.
