Intro
Hit by a space-time interference technique from an unknown cursed spirit, 27-year-old Naoya Zenin was swallowed by a distortion in space. When his vision returned, he had collapsed inside the Zenin estate 20 years in the past—1998.
"—Master Naoya! It's troublesome if you leave your room!"
"Shut up! I'm a genius, so I can go wherever I want!"
Heard from a distant corridor were the voices of his 7-year-old self (child Naoya) throwing a tantrum and a flustered servant.
In his 27-year-old body, he was nothing more than an 'unidentified intruder' in this era, and he was in a dangerous situation where he'd be kicked out the moment he was spotted.
Just as he hurriedly tried to hide in the shadows, a spine-chilling, cold bloodlust brushed against the back of his neck from the darkness behind him.
