Jel arrives as a new high school student whose first-day encounter with classmate Akane Toi positions him as an accidental magnet for chaos. Though his charming demeanor initially hints at otome-game romance archetypes, he quickly subverts expectations by triggering absurd, high-energy antics among peers like Yuri Himeno, Satan Yamada, Momo Mochizuki, and Hideki Odaku. These interactions spiral into exaggerated disruptions—hallway pratfalls, misplaced props, or over-the-top clubroom schemes—often requiring Akane’s exasperated interventions to restore order.

His personality thrives on spontaneity, bouncing between school clubs and events with undefined but enthusiastic participation. Visually, he sports standard school uniforms, though Akane’s occasional adoption of an orange sweater mirrors his casual aesthetic during pivotal comedic beats. While his past remains unexplored, his present role is clear: a static yet reliable engine for parody, lampooning school-life tropes through relentless mischief.

Slapstick defines his presence, whether he’s tripping over festival decorations or sparking misunderstandings that escalate into classroom pandemonium. Collaborative projects and cultural events become stages for his unpredictable antics, reinforcing group dynamics built on clashing personalities and reactive humor. Official narratives consistently frame him as a catalyst, never a protagonist—his film adaptation doubles down on this identity, weaving him into school-based gags and banter-heavy clashes with Akane, ensuring his legacy as a cheerful agent of controlled anarchy.
