Ifū Sakuma is a character from the original anime series Eren the Southpaw. He is an adult male character with brown eyes and short black hair that reaches approximately chin length. His visual design includes a moustache and goatee, and he typically wears a sweater, with a build described as muscular.

Within the narrative, Sakuma is established as a photographer. His professional identity places him within the competitive and high-pressure world of Japan's advertising industry, which serves as a central backdrop for the series. His personality is characterized by a pronounced self-absorption. He is identified as a specific archetype within the creative field: a narcissist who possesses an unshakable belief in his own abilities and the conviction that he is capable of accomplishing anything he sets his mind to. This categorization places him in contrast to other professional archetypes depicted in the story, such as logical pragmatists or charismatic sadists.

Regarding his role in the story and relationships with other characters, the available information indicates that he is a figure within the same professional circles as the protagonist, Koichi Asakura. His placement in the industry is defined by a senior creative director who outlines the different personality types that dominate the workplace, with Sakuma serving as a prime example of the self-absorbed narcissist archetype. Specific details about his background, his personal motivations beyond his professional ego, his key relationships with other named characters, his developmental arc throughout the series, and any notable abilities beyond his profession as a photographer are not available.
