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.

Elias' world was destroyed right in front of his eyes. Only after his transmigration did he learn that there was nothing natural about its destruction.“Mother, I passed my Practical Exams!

It only took a few months!”The person who destroyed his world was the eldest son of the family he was transmigrated to, the Ashborns.He could never forget his sister's cries when she suffered and eventually died from the virus that wreaked havoc in his world. And here he was, the person responsible, laughing.Elias wanted to repay the favor. He wanted to bring absolute ruination to these people. And for that, he had to play by their rules. He had to become the Architect of an Apocalypse…
