Tomohito Sugino operates as a student in Class E within a fantasy RPG parody world. He joins his classmates in collective missions targeting their instructor, the Demon King, engaging in adventures and combat scenarios that utilize the setting's unique gameplay mechanics. As part of Class E's group dynamics and tropes, Sugino contributes to assassination efforts through collaborative strategies.

He actively participates in group operations like infiltration missions, dungeon exploration, and boss battles, functioning within the class's combat unit. His role encompasses both frontline engagement and rear support, positioning him as a versatile combatant. Combat capabilities remain generalized across the class, with no distinct individual fighting style or assassination techniques specified for him separately from the group's collective approach.

Sugino's involvement remains fully integrated into Class E's ensemble actions, including attempts to bypass magical barriers or navigate parody RPG scenarios such as the "Nuru-nuru Assassination Test of Courage." Interactions with characters like Nagisa Shiota or Yukiko Kanzaki adhere to the group's established dynamics without individualized focus. The adaptation does not explore unique character development, personal backstory, specific relationships, aspirations, or romantic subplots for him, maintaining a cohesive emphasis on the class's shared objectives and comedic adventures.

Throughout the spin-off, his portrayal consistently supports Class E's efforts in team-based challenges, without standalone character arcs or evolution specific to this format.
