Description
Kotarou Tennouji is a main character in Kaginado, adapted from his role as the protagonist of Rewrite. In the lighthearted crossover setting of Kaginado Academy, his backstory as a superhuman hero who saved the world from a large-scale conflict is used for comedic parody rather than dramatic stakes. He brings the knowledge of his extraordinary past into the everyday antics of the school. He is much older than his youthful appearance suggests, a detail the series often plays for easygoing humor.

His personality is depicted as frivolous and arrogant, with a strong tendency to meddle in the affairs of others. He is confident, loud, and proactive, frequently taking charge of situations and driving the plot of individual episodes. The series highlights his boastful and somewhat greedy side, yet his underlying heroic nature and competence remain visible in his actions.

Kotarou's primary motivation in Kaginado is to enjoy a peaceful school life alongside his friends, often seeking fun and excitement in club activities, sports, and competitions against other characters. His role in the story is to be a central representative of the Rewrite series, interacting with the broader ensemble cast of protagonists from other Key works. He participates in various school events, such as forming the Neo Kendo Club with other skilled fighters or competing in absurdly physical soccer matches.

His key relationships revolve around the female leads from Rewrite, including Kotori Kanbe, Chihaya Ootori, Akane Senri, Shizuru Nakatsu, and Lucia Konohana, whom he often rallies into his schemes or casually leads into space. He also forms bonds with fellow male protagonists like Tomoya Okazaki and Riki Naoe, sharing a sense of camaraderie as veteran leads. His friendship with combat-capable characters such as Mai Kawasumi and Yuiko Kurugaya forms the basis for action-oriented comedy in the series.

While Kaginado is primarily a comedy without a deep overarching character arc, Kotarou experiences a form of comedic development by transitioning from a world-saving hero into a somewhat regular student who must navigate the absurdities of the crossover. His notable ability is Rewrite, which allows him to alter his own physiology, enhancing his physical strength and speed or growing weapons like swords from his body. In Kaginado, this ability is frequently used for flashy, over-the-top comedic effects, such as withstanding powerful blows or pulling off incredible feats in mundane school sports. His extensive combat experience from his original timeline also informs his slightly world-weary but ultimately helpful demeanor within the academy.
