Machina Arcanis: Two Worlds Collided - Chapter 28: Noises in the Dark I

Young Master Lu says, “My wife knows nothing at all and has a bad temper. You’d better not bully her.” Gu Mang watches silently as this man warns everyone who comes his way.

Konoha’s blue beast: “I want to prove that even if you don’t know ninjutsu or illusion, you can become an excellent ninja. This is the whole of my life. This is my way of ninja!”

The Roaring Emperor of Clover*: “I want to prove to everyone that no matter whether you are a poor ghost or an outcast, you can achieve great things!”

Hao Fan: “If there is any relationship between these two other than being equally inspirational, it is that my buddies were unlucky enough to transmigrate and become Rock Lee first.

- Description from novelbuddy

The world is full of mysteries. Strange, seemingly unexplainable events occur more often than we may realize. A young boy may catch an illness no doctor can explain. An office may catch fire for no apparent reason. And perhaps, someone may die a sudden and unexpected death – their bodies blighted beyond recognition.

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.

Initially, Kuro only faces minor threats, like weaker monsters and bandits. 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…
