Charles Euler

a very detached person who prefers time to think alone or with a few people with whom he has become close rather than activities based on less thinking or creativity. On the surface he appears to be an organized and methodical person, but over time it becomes clear that he also has a much less controlled side.
The reason for Charles's detachment is most likely his belief that the entire world around him is infected (with the exception of Vincent, whom he idolizes), which Charles both explicitly states and clearly demonstrates that all strangers, his mother, Scarlett and Henri appeared at least once in a distorted form. Despite his logical thoughtfulness, Charles has some difficulty in understanding views that are too far from his own.
