Duke Abel is a character from the anime adaptation of Shinichirō Nariie's manga, See You Tomorrow at the Food Court. Within the story, Duke Abel is not a physical person but rather a fictional character from a mobile social game that one of the main protagonists, Wada, is deeply invested in.

His design is that of an adult male with long blonde hair that reaches past his hips and green eyes. He is often depicted wearing a top hat and a boa, and has a notable facial mark as well as a single bang in his hairstyle."

Duke Abel's primary role is to serve as the object of Wada's passionate obsession. The series describes Wada as a mobile game addict who maintains a fervent love-hate relationship with a two-dimensional character, which is Duke Abel. The story of See You Tomorrow at the Food Court centers on the daily conversations between two high school girls, Wada and Yamamoto, at a shopping mall food court. In these discussions, Wada frequently vents her intense feelings, frustrations, and devotion regarding Duke Abel, making him a recurring topic that drives her part of the dialogue and reveals her inner world to her friend.

Because Duke Abel is a character from a game and not a living participant in the story's real world, his personality and motivations are not explored as a standalone individual. His characteristics are primarily defined by his role within the game's narrative and Wada's perception of him. His key relationship is therefore exclusively with Wada, who acts as his player and admirer. He serves as a catalyst for Wada's rants and passionate monologues, which form the core of her character development as she navigates her hobby alongside her school life. The series does not provide information on his background, personal motivations, or any notable abilities separate from the context of the fictional game he inhabits.
