Modern society is much better than the chaotic era they lived in. As a man reincarnated for the Nth time, Yanchong of the Ijichi family thought so for the Nth time.
That little girl Tengen, who had nothing going for her but her face, had become a major figure in the jujutsu world. Amazing.
Yanchong thought there was nothing wrong with living as a "non-sorcerer." Besides, ever since the Six Eyes appeared, those troublesome curse users had been behaving themselves a lot more... Going back to his old profession and practicing medicine to help people seemed like a good life.
Until the Shibuya Incident swept through the hospital where he worked. Everyone from the director and benefactors to his coworkers and patients was sliced into dust by Sukuna. Yanchong, who was late, left early, and overslept as usual, seemed to have gotten lucky and escaped unscathed.
But Yanchong found himself out of work. Not only was he unemployed, but the paper and data he'd spent more than a year writing were all on the computers and hard drives in his office. They were destroyed too!
Destroyed!
Yanchong fell into despair. Yanchong went into a frenzy.
He picked up the bow and arrows he hadn't touched in a thousand years. The man who considered himself neutral wore a dangerous expression!
Real name unknown. Reincarnated during both the Nara and Heian periods. A laid-back big shot who loves medicine and wants to retire in peace.
The timeline jumps around quite a bit. The protagonist goes on a rampage starting when Sukuna unleashes his big attack and destroys Shibuya.
If there is a heroine, it'll probably be Yorozu (the lovesick one). But what does a researcher need romance for?
Theme: Even a laid-back person will leap up when their deadline is looming and their data and paper are gone!
