Cian Cahlo, a normal graduating high school student--or was he really normal...?
In fact, he was actually the son and supposed to be the heir of the considered to be, by far, the deadliest and most infamous family of assassins in the world since ancient times. Was then trained from birth in the art of assassination--however, something unexpected happened. Summoned to another world along with his classmates, but, due to some reason, he was separated from them and then, instead of summoned, he was transmigrated in the body of the lascivious and infamous second prince of the Demon Empire.
Watch how Cian would cope up with his supposed to be a mission in this world and make a legend.
