Tamsy Caines

In reality, Tamsy is a cruel and sadistic man whose goal is to "break" Rudo, which led him to kill Regto in cold blood while Rudo watched, and to kidnap Amo and lock her in a basement to achieve his objectives. Throughout this time, he followed Rudo to the Cleaners. Tamsy believes in and refers to his actions as just, and claims to have been misunderstood his entire life. However, he is not angry about this, as he continues to move toward his current goal. While Rudo enjoys life on Earth more and more, Tamsy constantly plots ways to break him even further. When Tamsy accompanied Rudo to Kremmos Village, he was ecstatic about the fight that broke out between Rudo and Follo, and how angry farewells would be excellent fuel to break Rudo, laughing at his agony. When Follo didn't die, but instead awoke as a Giver, Tamsy didn't see it as a setback to her plan, but worked with it, allowing Rudo to live his life on Earth and enjoy life before the sacrifice Tamsy would make completely broke him.

Tamsy seems to know a lot more about the Watchman series than most. He's delighted with how useful it is and says his real name isn't as ridiculous as the one everyone gives him. When he saw how efficient Rudo is using his gloves now, he was saddened to realize how much had been wasted.

Tamsy appears to be a very reliable and kind member of the Cleaners. Her partner, Delmon, boasts that Tamsy always helps him. Tamsy maintains a calm and indifferent aura, even in the midst of battle, an aspect her fellow Cleaners rely on. Tamsy is completely accustomed to life in the Abyss and has an understanding of how things work that many lack. She seemed to downplay Rudo's shock at Gob's death, a common occurrence in the Abyss due to pollution, stating that it shouldn't upset him and that it wasn't her fault as Sphere. Later, Tamsy justified Master's kidnapping as "revenge" and explained that this is just how things are in the Abyss.

Despite her indifference to the suffering on the field, Tamsy maintains a kind and hopeful attitude toward her fellow Cleaners. Despite her constant arguments with Delmon, whom she often tells to shut up, Delmon can always count on Tamsy. Tamsy continued to express her support for Rudo, leading the latter to call her an "incredibly good guy."

Tamsy is a tall, slightly muscular young man with long blond hair and navy blue hair underneath. The blond hair is styled in a voluminous bun, and below, over his shoulders, is the navy blue hair parted and styled into two long tassels held in place with white bobby pins. His eyes, unlike all the other Givers seen in the series so far, have two layers when they glow while using his Life Instrument. There is a yellow layer over a blue layer, but when he is not using his powers, the blue is not present, so his eyes appear to lack pupils. He also has navy blue eyebrows and feminine blond eyelashes. He has a distinctive scar on the right side of his face that runs from his right eye to his chest. Tamsy is also missing the upper half of his right pinky finger.

His attire consists of an untucked white polo shirt, a navy tie, a choker like the other Cleaners', wide navy trousers, and black boots with white soles laced with white laces. He wears a loose, unbuttoned gray coat with a black stripe, a prominent yellow button bearing the Cleaners' logo, and long, wing-like sleeves that often cover his hands. He also has a silver lip piercing. Under his shirt, he wears a feather-like fabric, and on his back, a beige backpack containing his full face mask.

Like the Angel, his entire body is covered in a brown cloak, and he wears a gray mask with white circles (likely paint) around the eyes and some horizontal stitches on the forehead. His full face mask consists of a silver gas mask with a gray helmet that has two round, six-sided windows serving as eyes, along with a long wire inserted in the front. The top of the helmet is a sharp sheet of silver metal, and the helmet has four protruding spikes, two on each side.

The inner Tamsy, or the embodiment of Tamsy's true personality in her mind, looks much more feminine, as she wears her hair loose and the navy blue has completely disappeared. She also wears a light-colored, flowing jumpsuit.

The world of Gachiakuta is brutally divided between those who live in the Sphere and those who exist below it. The Sphere is a vast walled society where the privileged live, separated from the outcasts and those they consider inferior. Above it lies a seemingly civilized and orderly city, but this prosperity is maintained through the constant expulsion of those whom society no longer wants.
Everything the people of the Sphere consider trash—broken objects, waste, and even people deemed undesirable—ends up being dumped into the Abyss, a gigantic world located beneath the city. Far from being a simple landfill, the Abyss is a dangerous and virtually unknown place, filled with mountains of garbage, monstrous creatures, and remnants of civilization. Surviving there requires adapting to a hostile environment where any abandoned object can become either a tool or a hazard.
Within the Abyss exist Objects, things that have acquired a kind of life and power due to the feelings and value people have placed in them. Individuals capable of using this power are known as Givers. Through their abilities, they can use certain objects in extraordinary ways, transforming seemingly useless things into weapons or tools.
To combat the threats of the Abyss, there are the Cleaners, individuals specialized in confronting the creatures and cleaning up areas contaminated by garbage. Their work is not simply about collecting trash: they must fight against dangers inherent in this world and protect those trying to survive within it.
The society of Gachiakuta constantly revolves around one question: what determines the value of something? For those who live in the Sphere, anything that is no longer useful must be discarded. In the Abyss, however, abandoned objects can retain memories, feelings, and utility. What is considered trash above can become something valuable below.
It is a world marked by inequality, abandonment and survival, where garbage represents much more than waste: it represents what society decided no longer had value.
