X is a human NPC in Lucid Adventure.[1][2] He is one of the main characters in the X Ash webtoon. As an orphan growing up in the Forest of Poisons and Monsters, X had to steal to provide for himself and his adopted family. On one fateful day, he stole a dungeon Stone from Full Moon Ryu, the Captain of the Azure Knight Squad. Seeing X and Ash's potential, Full Moon Ryu took them under his wing and recommended them as candidates for the 99th Ragna.
The character's name is 엑스 in Korean. It translates to the letter "X" in English. The official English spelling for the character's name is "X" and not "Ex". The author himself spelt it as "X" in an Easter Egg in Hardcore Leveling Warrior Season 2 Episode 121. The image can be seen in the Notes & Trivia Section below.
