The greatest assassin who ever lived was reincarnated as the eldest son of an aristocratic assassin family. In this new and strange world, he is given a single mission—to kill the prophesied hero that will bring about the destruction of the human race.

He retained all his modern-day knowledge and experience from kills in his previous life. Now, with the secret techniques of his new assassin family and the magic of this strange world added to his arsenal, he could very well become the most unstoppable assassin in history.

“How amusing... To think that I would become an assassin again even after being reborn.”

The reincarnated legendary assassin climbs to even higher heights in this assassin fantasy story where anything can happen!
