Hori is a senior at Roman Academy and the well-respected president of the school’s Drama Club. From an early age, he showed a passion for theater, especially in performance and stage direction. However, his short height has been a recurring obstacle in casting, forcing him to step away from the spotlight despite his acting talent. Rather than abandon theater, Hori redirects his energy to stage design and production, becoming the behind-the-scenes force that ensures the club’s success.

He begins assisting Nozaki after discovering the manga artist’s need for background art. In a mutually beneficial arrangement, Hori agrees to work on the manga in exchange for drama scripts written by Nozaki. Despite claiming to dislike shoujo manga, Hori becomes invested in the process particularly when the drama and misunderstandings remind him of his real-life struggles with Kashima.

Hori is a relatively short but fit teenage boy with neatly styled brown hair and dark eyes. His eyebrows are thick and expressive, often emphasizing his intense or annoyed expressions. As a student, he wears the standard Roman Academy uniform, but when working on sets or manga, he is often seen in casual clothes or a painting smock, with sleeves rolled up and tools in hand.

Though his height is a frequent source of frustration, Hori carries himself with confidence and authority, particularly when giving directions or managing the Drama Club.

Hori is known for being hardworking, responsible, and no-nonsense, particularly when it comes to theatrical production. He has a short temper and is easily annoyed, especially by the Drama Club’s “Prince,” Yuu Kashima, whose unpredictable and flirtatious antics frequently derail rehearsals and test his patience. Despite his stern demeanor, Hori is deeply committed to his craft and cares about the success of his club and its members.

Although he claims to be indifferent toward shoujo manga, Hori often finds himself emotionally invested in Nozaki’s storylines, especially when parallels arise between the manga and his own dramatic daily life. His quick temper, tsundere tendencies, and tendency to overreact are played for comedy, making him one of the more animated and relatable characters in the series.

• Drama Club President
  As president of the Drama Club, Hori is constantly balancing the creative and logistical needs of the group. He is a talented actor, but his inability to land leading roles due to his height leads him to focus on behind-the-scenes contributions. He is particularly known for creating elaborate stage backdrops and ensuring the smooth execution of performances.

• Manga Assistant
  Hori becomes part of Nozaki’s manga team when the latter discovers his skill in drawing detailed backgrounds. The partnership is purely transactional at first scripts in exchange for artwork—but over time, Hori becomes more involved and emotionally invested in the creative process. He often gives feedback on character interactions, particularly when he sees reflections of his own life in the manga.

• Chaos with Kashima
  A major source of comedy comes from Hori’s dynamic with Kashima Yuu, his Drama Club underclassman. Her charming, princely persona attracts the attention of both students and faculty, but her thoughtless behavior constantly throws the club into disarray. Hori’s reactions to Kashima’s antics ranging from yelling to physical comedy highlight his role as the straight man in their oddball duo.
