(JJK But it's the Heian Era/Golden Age of Curses! He time travels to the past!)

Satoru rarely took his mission's seriously, with being the strongest he truly had no worry that any curses would be able to land even a single hit on him. He was arrogant, but rightfully so.

Normally.

However while he was in the middle of completing a special-grade mission and finishing exorcising a curse he didn't notice another curse sneaking up behind him and somehow getting through his infinity.

A searing light erupted around him, temporarily rendering six-eyes useless as all of his senses were assaulted at once. Satoru's body crashed to the ground in a heap, blinking away dark spots.

The first thing he noticed was just how quiet it was everywhere, no city ambience no matter how hard Satoru listened. The second—was the terrified person standing over him.

They were dressed in colorful traditional clothing, holding a wooden bucket full of well-water in one hand, the stars bright from a lack of light pollution behind them.

Satoru could only wander what mess he got himself into this time.
