The World's Finest Assassin Wiki

Light Novel Volume 3 is the third volume of the Sekai Saikō no Ansatsusha, Isekai Kizoku ni Tensei suru Light Novel. It is written by Tsukiyo Rui with illustrations by Reia.


After his success in battle with a demon, Lugh is made a Holy Knight by the Alvanian Kingdom and tasked with slaying more of the creatures. The problem is, only the hero can actually fell demons. Such a setback isn’t going to stop the world’s greatest assassin, however, and Lugh gets to work devising a spell to kill the supposedly immortal beings. Unfortunately, the only way to test this new magic is in a real battle! Failure promises certain doom, but triumph may turn out to be just as perilous if Lugh isn’t careful...
