Shogo Haseoka is a supporting character in the series who serves as a grounded observational presence amidst the extraordinary events surrounding the giant god Ranga. His background reveals a man with a complex and somewhat fallen past. At one time, he was regarded as a highly talented filmmaker, but his career in the industry suffered a significant downfall after he produced a documentary that was considered too unconventional or controversial by mainstream standards.

In the present day, Haseoka operates a small, simple restaurant by himself, living a modest and independent life. His re-entry into the orbit of the Shimabara sisters begins not through his culinary work, but through his skills as a cameraman. He is initially hired to follow and discreetly record the activities of the eldest sister, Minami Shimabara. After the initial chaos surrounding Ranga's arrival subsides, he continues to work as an independent contractor, primarily filming the ongoing events related to the god for the news organization that employs Minami.

Haseokas personality is defined by a down-to-earth and questioning nature. He possesses the innate curiosity and detached eye of a documentary filmmaker, always observing and analyzing how people react to the presence of Ranga. He holds a specific belief that the giant god acts as a catalyst, causing many individuals to behave differently or adopt personas that are not true to themselves. This perspective gives him a unique vantage point, allowing him to see through pretense. He notably admires Minami for being an exception to this rule, observing that despite the fame and chaos that Ranga has brought into her life, she remains fundamentally the same person he knew before the god ever appeared in Tokyo.

Beyond his work in media and food service, Haseoka maintains connections with local yakuza, though he does not actively participate in their activities. This connection hints at a deeper, more ambiguous history and provides him with access to information and circles outside of mainstream society. His role in the story is primarily that of an observer and a chronicler, using his camera to document the strange new reality. However, he is not a passive figure; his past as a filmmaker eventually catches up with him, forcing him to confront personal ghosts and the consequences of his earlier work. Through these challenges, his character development involves reconciling his past failures with his present principles, continuing to question the world around him while maintaining a steady, if unconventional, life running his restaurant and watching over Minami from behind his lens. His notable ability is his keen eye for truth and human behavior, a skill honed from his years as a documentarian, which allows him to capture events and perceive character traits that others might miss.
