Isen is a lighthearted and ambitious student known for his role as a school journalist and his ability to sniff out the latest gossip. While he is dedicated to his work when given a compelling story, he is also easily the most carefree and comedic among his more serious friends, Blyke and Remi. Isen often jokes around, sometimes to the point of distraction—as shown during his interview with John, where he was caught doodling instead of taking notes. He’s also known for being girl-crazy, to the extent of stalking girls from other schools, and thrives on school rumors, often spreading them enthusiastically. However, after uncovering a particularly dangerous secret, Isen becomes more cautious, prioritizing safety over sensationalism.

Despite his charm and power, Isen struggles with confidence and has a reputation for being cowardly and weak-willed. He is quick to back down under pressure, especially from authority figures, and has admitted that leadership roles like Head of Press are overwhelming for him. He often runs from problems to avoid conflict, aware of his limitations and anxious about failing others’ expectations—particularly Arlo’s. Still, Isen is not entirely unreliable; when it truly matters, he can step up and take action, even if he later regrets the consequences. His mix of comic relief, self-awareness, and reluctant bravery makes him a complex but ultimately endearing figure in Wellston's student hierarchy.
