Multiverse: What Do You Mean I'm the Last Traditional Onmyoji?

After transmigrating into a Japanese family of onmyoji, he became an onmyoji himself. As spiritual qi revival brought ever more spirits and monsters into the world, Shinki Sakuya followed his grandfather's last wishes and decided to live a free and happy life. He absolutely refused to become a wage slave tasked with saving the world.

Saving the world was out of the question. He'd take the occasional exorcism job, just enough to make ends meet.

But before he could enjoy more than a few days of ordinary life, he ran into a group of mysterious high school girl agents equipped with modern exorcism techniques.

Wait, are you telling me I'm the last traditional onmyoji in Japan? What era is this? Who still uses traditional methods to exorcise demons? The times have changed? No, I'll prove with my astounding power that the times haven't changed one bit!

...Anyway, this is a lighthearted romantic comedy about everyday life.
