After thinking for a long time, he decided that he wanted them all!

Conan: This is impossible murder! Is there really a ghost?

Sagawa Yan looked at the shikigami flying in the sky and smiled without saying a word.

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…

A little ruffian who fought recklessly without any morals and bottomline accidentally time-traveled to parallel space and became a Key Case Investigation Team agent. The huge change in identity had him creating chaos in the police station. However, a strange miracle system helped him repeatedly solve mysterious cases, turning him into an impudent ruffian detective!

Young clerk Loya crossed and came to the world of the legendary OP. As a traversal party, he naturally had golden fingers, but his golden fingers turned out to be the dragon annihilator system from the demon tail!

Is still the ice dragon dragon wizard!

————-

What interesting chemical reactions occur when two worlds with completely different power systems touch together?

When the laser of the ape meets the roar of the ice dragon, what will it look like?
When the green pheasant saw the mouth of the dysentery being eaten by a mouthful, what kind of stunned?

“If it wasn’t for fear of becoming a dragon, I would have unified the world!” Said Loya.
“Don’t you dare say that you are seasick?” Carp buttoned his nostrils and smiled dismissively.
