Garbage is a central figure in the dark fantasy series Blade & Bastard, appearing as a feral young swordswoman whose introduction dramatically alters the course of the protagonist's life. Her background is one of profound hardship and mystery. She is introduced as the sole survivor of a massacred adventuring party, discovered within the depths of a deadly dungeon. Before this, her history is even darker; she is known to have been a former slave, a past that has left her completely illiterate and deeply scarred. Her name, Garbage, is not a chosen moniker but a label she has been given, a point that other characters recognize as cruel and dehumanizing, yet it remains the only name she is known by.

Physically, Garbage is described as having a wiry frame and messy red hair. Her hair color, along with compelling eyes, connects her to the royal family of the setting, hinting at a significant and potentially cursed bloodline that becomes more relevant as the story progresses. Her most distinctive trait, however, is her behavior. Due to her traumatic past and stunted development, she does not speak. Her communication is entirely non-verbal, consisting primarily of animalistic sounds such as barks, growls, and yips, leading others to frequently compare her to a dog or a wild animal. This behavior is not an act; it is a core part of her feral nature, shaping how she interacts with the world and how the world perceives her.

Garbage's personality is defined by her raw, instinctual nature rather than complex emotions or societal norms. She is not depicted as kind, devoted, or particularly social. Her primary mode of expression and interaction is through action, specifically combat. She is fiercely protective in her own way, lacking guile and operating on a simple, direct logic. Despite being treated more like a stray animal than a person by some, she demonstrates a capacity for loyalty and forms a powerful, if unconventional, bond with the protagonist, Iarumas.

Her primary motivation is not driven by lofty goals or a desire for treasure. Initially, her survival and proximity to Iarumas form the core of her drive. As she accompanies him, her role becomes more defined by protecting her new companion and party. Underneath her feral exterior, there is a hint of a more significant personal history tied to the royal family's curse, suggesting that uncovering her true identity could become a major motivation in future storylines. Her development is subtle; it is seen more in how others begin to rely on her strength and in the grudging acceptance she earns, rather than a dramatic change in her own behavior.

In the story, Garbage serves as a pivotal catalyst for Iarumas. Before meeting her, he was a detached, cynical figure who consorted primarily with the dead and worked alone. He is initially scorned by other adventurers for his cold, utilitarian attitude. Garbage, as the sole survivor of a tragedy, becomes his first true companion, pulling him away from his solitary existence and forcing him to engage with the living once more. Her role within the party is that of a formidable frontline fighter. Despite her small and wiry frame, she possesses ridiculous strength, wielding a greatsword with deadly efficiency and single-handedly tearing through the dungeon's monstrous inhabitants. She is the party's shield and sword, providing the muscle that allows Iarumas to focus on his strategic and corpse-retrieving duties.

Her key relationships are primarily with the main party members. Her bond with Iarumas is the most significant. While he initially regards her with an indifference similar to how he treats everything else, he accepts her feral nature without judgment, and a mutual trust develops between the silent swordswoman and the pragmatic adventurer. She is also a member of a growing party that includes Raraja, an inexperienced thief, and Sister Ainikki, a priestess who can resurrect the dead. While she interacts with them in her own limited way, these connections tie her to a larger group dynamic, moving her away from being a lone, feral survivor.

Regarding her abilities, Garbage is a purely physical powerhouse. As a barbarian-type fighter, her notable abilities do not include magic or complex tactics. Instead, she relies on her incredible physical strength, speed, and a seemingly unquenchable ferocity in battle. She is capable of wielding a massive greatsword that would be unwieldy for someone of her size, and she uses it to devastating effect against the dungeon's monsters and other enemies. Her combat style is as feral as her personality, making her an unpredictable and terrifying opponent. Her animalistic instincts also likely contribute to her survival skills, making her highly attuned to danger in the dungeon environment.
