Elex is a kindergarten teacher in Edelstein. At night he is a trainer for the Resistance prior to the Heroes of Maple update. As of said update, he is the Warrior job instructor, specifically for Blaster. He has a crush on Leonore, and comes up with many ways to try to impress her, through cooking Serpents and giving her Dahlia flowers. He says this is worse than Romeo and Juliet since she is a Black Wings member and he is a civilian/resistance member. He even goes as far as to pay much money to Ace to buy a Shiny Diamond for her. In the end, Leonore sends a letter back to Elex.
In FriendStory, his counterpart manages construction over the Sunset Lot playground. Irena briefly works for his company in an effort to raise funds for her band, but Damien had already been working there before her for the same reason. This causes Irena to try to overperform him, but fails miserably and drops a large pile of cement onto the ground, promptly causing Elex to fire her.
Elex was originally the basic training instructor for the Resistance, but with the arrival of the Heroes of Maple update, and the introduction of the Blaster class, Elex was made into their job instructor, with Ferdi replacing his original role.
