Oliver Laurents Friedheim is a commoner from the Kingdom of Hein who serves as the personal attendant to Crown Prince Arnold Hein. He once aspired to become a knight, but an injury ended that ambition, leading him to enter the prince's service when Arnold was nine years old. Oliver possesses silver hair, swept to the right in styled bangs, and lilac-colored eyes. He typically wears a pale blue coat with silver lining and a black interior, a grey vest, black dress pants, and silver loafers. Some theories propose that Oliver may harbor ulterior motives and could be a hidden villain manipulating events from behind the scenes. His physical design bears similarities to Prince Kyle Morgan Cleverly, a figure from another character’s past, prompting speculation about a possible connection or that Oliver possesses awareness of the story’s time loops. His design is also modeled after Sephiroth from *Final Fantasy VII*, which some interpretations suggest may hint at an antagonistic role.
