Do not underestimate the act of tilling the soil. The practice of farming holds the power to command the clouds and dictate the rainfall with a mere flick of the wrist. Similarly, never undervalue the humble farmer, who might draw the gaze of stunning women, and vie for the affections of fluttering butterflies.A stunning journalist makes for a worthy companion, and even an aloof, imperious law enforcement officer could be brought to plead for mercy.

I may appear as a regular individual, but through a stroke of fortune, I have embarked on a captivating journey, dancing amidst the wind and the clouds!

Following a brutal and tortured death, a former assassin, known only by his codename Kuro, is given the opportunity to reincarnate in another world, a world with magic and monsters. Armed with an unrivaled healing factor and an inhumane pain threshold, Kuro opts to go for a reckless direct approach in this world instead of a stealthy and cautious one, and as a result, slowly gains attention bit by bit.

Having previously been a loner in his old life, he interacts and befriends people for the first time in his existence, however, his blunt nature also sees him making just as many enemies, both big and small. By combining his old assassin skills with the magic powers of this world, along with his high resistance to pain and rapid regeneration, he doesn't take long to establish himself as a formidable force in this world.

But before too long, the threats slowly but surely become more and more severe…from Zombies to a bloodthirsty empire to Vampires and Demons, and even divine beings…however, as the enemies he faces grow stronger, so does Kuro, gaining rare powers that have never or rarely ever been seen in this world…
