Gachiakuta

On an emotional level, Rudo is explosive and transparent. He can't hide his feelings or remain calm when something affects him. He gets angry easily, is quickly frustrated, and reacts impulsively, but he also displays a profound sensitivity to the suffering of others. He is not indifferent to violence or pain, even when forced to live with them. This contradiction—toughness on the outside, sensitivity on the inside—is central to his character.

Rudo doesn't fit in with the Cleaners right away. He doesn't share their normalization of the Abyss or their pragmatic view of the garbage and the beasts. While many Cleaners have already accepted this world as it is, Rudo still actively rejects it. He doesn't want to fully adapt; he wants to understand why the world works this way and, deep down, change something, even if he's not sure how.

Rudo embodies the thematic core of Gachiakuta: the idea that what is discarded, despised, or deemed useless still holds value. He himself is proof of this. His existence contradicts the system that decides what is valuable and what is not, and that is why he is so unsettling to both the upper society and the Abyss.

In short, Rudo is neither a classic hero nor a quiet chosen one. He's a wounded, angry, sensitive, and stubborn boy whose greatest strength lies not only in his power but also in his inability to accept a world that treats people and things like garbage. He finds it hard to receive physical affection; he stays very still, not knowing how to react (he's such a little blob!! :)

Rudo is the protagonist of Gachiakuta, a boy defined from the start by the rejection and contempt of the world he lives in. He grows up in the upper city, a place presented as "clean" and orderly, but which in reality operates on exclusion. Rudo lives on the margins of this society, treated as inferior, suspicious, and easily discarded. From childhood, he carries the stigma of being "trash," not only because of his social standing, but also because of the way others look at him and judge him.

One of Rudo's most important traits is his relationship with objects. Unlike the rest of the people in the upper world, who throw things away without a second thought, Rudo feels a genuine attachment to them. For him, objects are neither replaceable nor useless; they have history, value, and meaning. This isn't presented as a superficial quirk, but as something deeply connected to his understanding of the world. Rudo hates waste and contempt, and this hatred stems from having been treated as disposable himself.

When he is unjustly accused and thrown into the Abyss, Rudo doesn't react with resignation, but with an intense mix of rage, confusion, and pain. He doesn't accept what happens to him as "fate," and this refusal to surrender is a constant in his character. In the Abyss, his anger doesn't disappear, but it transforms: it ceases to be mere rage and begins to become a force that drives him to survive and move forward, even when everything around him is hostile.

In combat, Rudo is not initially refined or strategic. He fights in a raw, instinctive, and emotional way. His strength doesn't come from technique, but from the intensity with which he clings to what he feels. As the story progresses, it becomes clear that his connection to objects is abnormally strong, even compared to the Cleaners'. Rudo doesn't just use objects: he understands and feels them, almost as if he can perceive what they hold within. This makes him dangerous, but

Riyo: Her behavior suggests she's completely adapted to the Abyss. Her past isn't explored in much depth, but her actions make it clear that violence is a normal part of her routine.

Rubion Gray Gris is one of the most reserved and analytical supporters (he has no vital instrument). He appears serious, quiet, and focused on understanding the Abyss rather than direct confrontation. His Jinki is a book, and through it, his role as someone interested in recording, analyzing, and understanding how objects, the Trash Beasts, and the world system itself function is reinforced. Gris often explains important concepts, acting as an informative figure within the group. He is not emotionally expressive and maintains a certain distance from others, but he is neither hostile nor indifferent; rather, he is focused on his work and knowledge.

Semiu Grier Semiu is a Cleaner with a quiet and observant nature. She speaks little and rarely expresses her thoughts directly, but the manga makes it clear that she perceives details that others overlook. Her Jinki is related to needles or thread, and its use suggests precision and control. Semiu shows a particular interest in Rudo, especially in his unusual way of interacting with objects, and seems to notice his potential before others. Although her demeanor is distant, she is not portrayed as cold or insensitive, but rather as someone who processes the world in a more internal and reserved way.

An object he uses both defensively and offensively, adapting it to different situations. The manga shows that Enjin doesn't dramatize or idealize his work: cleaning is simply what he does. With Rudo, he's more curious than protective, observing his relationship with objects without softening the reality of the Abyss. He doesn't present himself as a classic mentor, but as someone who lets Rudo learn by directly confronting the consequences of the world he fell into.

Zanka Nijiku Zanka is a Cleaner characterized by his deep distrust of others and a nervous, reactive demeanor. Although he often expresses himself aggressively and dramatically, the manga makes it clear that this facade masks insecurity and anxiety. Zanka is easily agitated, becomes defensive, and reacts emotionally to overwhelming situations, making him quite transparent. Contrary to what might initially seem, he is not cruel nor does he enjoy violence; rather, he acts this way because he doesn't know how to handle fear and uncertainty well. One clearly perceptible trait is that Zanka responds very positively to recognition: when praised or validated, he calms down, becomes more open, and less hostile. This suggests that he needs approval and that his initial harshness functions as a defense mechanism. His behavior presents him as someone emotionally fragile, yet genuine.

Riyo Reaper Riyo is a Cleaner distinguished by her carefree attitude toward danger and violence. She appears smiling and playful even during fights, which creates an unsettling feeling in those around her. The manga doesn't portray her as chaotic or out of control; on the contrary, Riyo seems fully aware of her actions and the effect they have on others. Her Jinki is a pair of scissors, which she uses with natural ease and precision. Riyo expresses no guilt or inner conflict regarding her work as a Cleaner, nor her behavior.

The manga shows that thanks to them, Semiu can perceive things that others cannot, especially those related to objects and their value. While the exact capabilities of the lenses aren't detailed, it's clear that his IV is linked to perception and observation, not attack. This is a clear example of how Vital Instruments aren't always for fighting, but also for understanding and detecting.

Rubion Gray Gris Rubion does not possess a Vital Instrument. This is canon. Despite being part of the Cleaners, Gris does not use any awakened objects. His role within the group is tied to knowledge, analysis, and understanding of the Abyss, not the direct use of Vital Instruments. The manga does not suggest that he has a hidden or latent Vital Instrument; he is simply not a Vital Instrument user.

Rude Rudo's Vital Instrument is a pair of gloves. These gloves allow him to interact with objects in the Abyss in a way unlike any other character. Through them, Rudo can extract and manifest the latent power of objects, making him an anomaly even among IV users. The manga makes it clear that the gloves don't function as a traditional weapon, but rather as a means to activate and channel the value of things. His IV is directly linked to his unique way of relating to objects, and that's why his potential is treated as something extraordinary.

Final canon, no discussion: Enjin → umbrella Zanka → walking stick Riyo → scissors Semiu → lenses Gray → has no IV Rudo → gloves

Enjin Enjin is one of the most experienced Cleaners who appear at the beginning of Gachiakuta and is the one who introduces Rudo to the true workings of the Abyss. His attitude is seemingly relaxed and carefree; he tends to speak casually and doesn't behave like an authoritarian or solemn figure. However, this lightheartedness contrasts sharply with his clearly high skill in combat. His Jinki is an umbrella, an object he uses both in

Enjin Enjin's Vital Instrument is an umbrella. In Gachiakuta, it's clearly shown that this umbrella isn't merely decorative or symbolic, but a fully functional IV for combat. The umbrella can transform and adapt, allowing Enjin to use it both offensively and defensively. Its use is versatile and fluid, demonstrating that Enjin has used it for a long time and has complete mastery over it. The manga doesn't go into exhaustive technical details about all its limitations, but it does make it clear that the umbrella is sturdy, reliable, and capable of directly confronting the Trash Beasts. It's an active and confirmed IV.

Zanka Nijiku Zanka's Vital Instrument is a staff. It's a simple IV, without complex mechanisms or exaggerated transformations. The staff is designed for direct combat: striking, blocking, and resisting. The manga shows Zanka using it impulsively and somewhat clumsily, but effectively. There's no indication of special abilities beyond its capacity as a blunt weapon, enhanced by Zanka's emotional bond with the object. The staff reflects that an IV doesn't need to be sophisticated to be dangerous, as long as there's genuine attachment and consistent use.

Riyo Reaper Riyo's Vital Instrument is a pair of scissors. These scissors function as a clearly offensive IV. In the manga, Riyo uses them with complete ease, as if they were an extension of her body. Detailed technical rules regarding their range or limitations are not explained, but it is shown that they are capable of directly damaging and eliminating Junk Beasts. The scissors require no visible activations or rituals; they simply function in Riyo's hands, reinforcing the fact that her IV is fully awakened and stabilized.

Semiu Grier Semiu's Vital Instrument is his glasses. Unlike other IVs, his glasses aren't focused on physical combat. The manga shows that thanks to
