Inumael Growner, alias Innumael Grauer, navigates the Wahrheit Empire’s gritty underbelly as a delivery transporter, laboring to sustain himself and his younger sister Sissel, entrusted to their parents. Dubbed “dog” by colleagues for unflinching loyalty and reliability, he channels these traits into shielding those he cares for. Born into an assassin dynasty under his father’s ruthless command, he honed lethal skills from childhood but severed ties after witnessing his father’s brutality, seeking absolution through military service.

A fateful delivery job spirals into disaster when he unknowingly transports illegal weapons, resulting in arrest and criminal branding. Rescued by the shadowy Headkeeper syndicate, he is thrust into their smuggling operations, resisting violence at first but mastering survival tactics under pressure. Haunted by his family’s legacy, he grapples with moral boundaries, compelled to kill to defend allies such as Schaake Gutheil during clashes with imperial troops.

Central to his journey are his fiercely protective bond with Sissel—her safety a relentless driving force—and his fraught alliance with soldier Leocadio Wöhler, bound by their shared entanglement in the smuggling debacle. Once a pawn of circumstance, he evolves into a calculated rebel against imperial corruption, leveraging strategic acumen to challenge systemic decay while wrestling with guilt over past deeds.

His quest for peace clashes with a brutal world, forcing sacrifices where others’ survival eclipses his own. Though combat prowess from his assassin upbringing surfaces in critical moments, he deliberately shuns excess violence. The unresolved clash between inherited instincts and hard-won ethics fuels his evolution, hinting at pivotal choices that may shape the empire’s future.
