One of the main themes could be the struggle against a pre - determined system. The characters in the loop are likely trying to break free from the constraints of the loop.
Another theme might be self - discovery. As the characters are in this loop, they have to figure out who they are and what they want in the face of this strange situation. They might be constantly evolving and learning about themselves as they try to understand the loop. For example, they may discover new abilities or aspects of their personalities that help them either cope with or try to escape the loop.
One of the main themes is the exploration of childhood wonder. The stories in the graphic novel often revolve around kids in a unique world filled with strange machines and phenomena.

Since the characters are reliving the same time period, they often use this opportunity to better themselves, like learning new skills or changing their personalities.

Love and friendship are also common themes. The time loop can test and strengthen relationships. Maybe in one loop, a character loses a friend due to a misunderstanding, but in subsequent loops, they work hard to fix it. And in terms of love, it could be a situation where the main character realizes their love for someone through the repeated experiences in the time loop.
