The main characters in the 'euler graphic novel' could be diverse. There might be a group of adventurers who use Eulerian principles to solve problems in a strange land. One character could be the leader, strong - willed and intelligent, leading the group. Another could be the comic relief, providing some humor while they struggle with the complex ideas. And perhaps there is a mysterious character who seems to have a deeper understanding of Euler's work from the start and helps the others along the way.
The 'euler graphic novel' could be important because it might bring a fresh perspective. If it's related to Euler, it could use his ideas like Eulerian paths or circuits in its plot or visual design.

For example, the story could be about a character navigating through a maze - like world based on Eulerian paths.
