Description
Makoto Teruhashi is a character in The Disastrous Life of Saiki K. who operates under the public stage name Toru Mugami. He is introduced as a top idol and a wildly popular young actor, known for his good looks, charm, and acting talent. In private, he is the older brother of Kokomi Teruhashi. His background as a celebrity gives him significant public influence, but his personal life is dominated by an intense and possessive attachment to his sister.

Personality-wise, Makoto presents a likable and friendly demeanor in his public persona, which makes him popular with female fans and even some male peers, such as Shun Kaidou who admires him. However, this outward charm conceals a deeply obsessive and possessive nature, particularly regarding Kokomi. He harbors a severe sister complex, viewing any male attention toward her as a threat and reacting with jealousy and hostility. His motivations are primarily driven by this fixation: he wishes to keep Kokomi to himself and actively resents Kusuo Saiki for being close to her. At times, his stated dream is to marry his sister, underscoring the extreme and comedic nature of his devotion.

In the story, Makoto serves as a recurring supporting character and a source of comic conflict. He often appears in disguise to spy on Kokomi and Saiki, and he uses his acting skills to maintain a normal facade. His role is that of an overprotective and obsessive sibling whose actions frequently disrupt Saiki’s attempts at a peaceful life. Key relationships include his sister Kokomi, whom he idolizes and seeks to control, and Saiki, whom he views as a romantic rival. He also has a one-sided connection with Kaidou, who is impressed by him. Over the course of the series, Makoto does not undergo significant character development; his obsessive traits remain consistent, serving as a running gag rather than a source of growth.

Notable abilities include his professional acting skills, which allow him to convincingly play various roles on screen and also to disguise himself in real life. His public charisma and fame give him social influence, but he has no supernatural powers. His physical attributes include blue hair and blue eyes, and he stands at 178 centimeters tall.
