Different Version of Japan's Top Swordsman

Speaking of Inoue, I thought of that cross talk show, where you can take whatever surname you want, under the pine trees, by the river, and Inoue... Hahaha

A very good novel, full of positive energy. The Japanese world of monsters and ghosts. The protagonist only kills monsters and doesn't do much killing.

What happens if you get poisoned every morning? Now you not only recommend poison, but also books about eunuchs?
