Laos Kanon Jilfor

He is the Hero Academy's Rank 4 and a student from the selective class "Jerga-Kanon".
Laos is straightforward, temperamental, and also a bit of a battle maniac. He speaks bluntly and impolitely. Raos was initially arrogant and narrow-minded

As a member of the "Jerga-Kanon" class, Laos is likely to be a reincarnated hero from the past. However, he was led to believe that he was the reincarnation of the Hero Kanon's third source, taking the name of {Laos Kanon Jilfor} as a result. Because the "Jerga-Kanon" students were taught to use the holy spell Aske, which was tainted by one-half of Jerga's source, they were slowly brainwashed into hating demons.
