Gaku Serizawa

Gaku is serious, independent and strongly attached to life in nature. He is skeptical of the widespread reliance on OrderMaids and prefers the self-sufficiency associated with living away from the technologically saturated environment of the city.

His opinions are not completely inflexible. Direct experience with Roboco challenges his assumptions, and he is capable of changing his perspective when confronted with evidence that contradicts what he believes.

Gaku's mature appearance and manner also become part of the comedy surrounding him. At only twenty, his glasses, beard and solitary profession make him look and behave like someone considerably older.

Gaku is an ordinary human without established supernatural abilities. Living and working in the mountains gives him practical familiarity with wilderness conditions and the natural environment.

His profession as a nature writer depends on observation and experience rather than combat ability. Consequently, encounters with dangerous wildlife can still place him in situations he cannot resolve through physical strength alone.

Gaku appears as a nature writer living in the mountains, providing a viewpoint far removed from Bondo's technology-filled suburban life. His skepticism toward OrderMaids establishes an immediate ideological contrast with Roboco.

His encounter with the bear Kumahachi places him in genuine danger. Roboco intervenes, and her actions force Gaku to confront the fact that an OrderMaid can possess qualities and capabilities that do not fit his dismissive assumptions about machines.

Through Gaku, the series briefly shifts its usual OrderMaid comedy into a story about the perceived opposition between technology and nature, while still resolving that theme through Roboco's characteristically excessive behavior.

Roboco saves Gaku during his mountain encounter and challenges his negative assumptions about OrderMaids.

Kumahachi is the bear whose encounter with Gaku creates the dangerous situation that brings Roboco into direct conflict with the wilderness around him.
