Description
Edgar Crosstruger is a supporting character who hails from the fantasy world and serves as a secondary figure in the narrative focused on the uncle's past. He is a young swordsman with a composed and earnest demeanor, characterized by his blue eyes and short purple hair that falls to his ears. Edgar is the childhood friend of the elf Alicia Edelcia and forms an adventuring party with her, positioning him as a classic rival and companion within their group.

In terms of personality, Edgar strives to present himself as a cool and competent hero. He takes his role as a swordsman seriously and has a notable habit of naming swords that he particularly likes, showing a sentimental and proud attachment to his weapons. His motivations are rooted in the desire to be a reliable adventurer and to protect his friends, though he often finds his serious moments undercut by the overwhelming and bizarre power of the uncle, who frequently steals the spotlight from him.

Edgar's role in the story is primarily tied to the flashbacks of the uncle's adventures in the other world. He acts as a contrast to the uncle's unconventional and overpowered methods, representing a more traditional fantasy hero. One of the most significant events defining his reputation involves the repelling of a horde of goblins. During an incident where the uncle was responsible for a massive feat of destruction, specifically cutting down a mountain, the general populace mistakenly credited Edgar for the deed. As a result, he was bestowed the epithet "Mountain Slayer," a title that carries a mix of irony and sincere admiration given he did not actually perform the act. His key relationships are with Alicia, his childhood friend and party member, and with the uncle, whose existence constantly challenges Edgar's understanding of strength and heroism.

Throughout the story, Edgar experiences a form of reluctant development as he repeatedly fails to assert his own competence in the face of the uncle's reality-defying abilities. Despite his lack of the uncle's magical prowess, his unwavering determination and adherence to the role of a traditional swordsman highlight his growth as a character who learns to accept his place in a world far stranger than he anticipated. His notable abilities center on his skill with a blade, demonstrated through his swordsmanship and combat experience as an adventurer, which, while respectable by normal standards, are consistently overshadowed by the uncle's legendary powers.
