Shout operates as one half of London's nocturnal disposal duo "Nico Nico Trush Box," specializing in eliminating uniquely challenging refuse deemed impossible through conventional channels. His expertise covers emotionally fraught items like a once-used health appliance, unwearably worn sneakers, collections of ex-girlfriends, and mistress chat histories. He demonstrates relevant technical aptitude through proficiency in mechanical modification.

Shout embodies a "rigorous samurai spirit" and maintains a gentlemanly demeanor, particularly evident when supporting Makina—a witch seeking to discard her grimoire and relinquish her magical identity. This request forms the central narrative thrust as Shout and his partner Crunch undertake disposing of the enchanted book, complicated by its supernatural properties. Their professional capability to handle "the hardest garbage in the world" positions them as uniquely suited for this challenge, though the outcome remains unspecified.

His partnership with Crunch establishes a complementary dynamic: Crunch handles programming and operates silently, while Shout engages directly in interactions. Together they form a cohesive team dedicated to their unconventional profession. No personal history, physical description, or significant character evolution beyond this professional context is detailed.
