Ginti is a tall and imposing man with sharp golden eyes and distinctive red spiky hair, which is tied back into a small ponytail. His intense gaze and fiery hair complement his bold and confrontational nature.

Like other arbiters, Ginti wears a version of the arbiter uniform, consisting of a white button-up shirt with the sleeves rolled up to his elbows, a black vest with his arbiter pin affixed to the left side, black pants, a brown belt, a dark apron, and polished leather shoes. Unlike the more neatly presented Decim, Ginti wears his uniform in a slightly disheveled manner, often leaving the top button of his collar undone, which reflects his more casual and rebellious attitude.

Ginti is known for his rough, blunt, and impatient nature, often displaying irritation when dealing with guests or fellow arbiters. He approaches his role as an arbiter with a strict, no-nonsense attitude, viewing it purely as a job to be done efficiently rather than a philosophical or emotional process. He prefers to complete judgments quickly and rarely shows interest in the emotional or psychological complexities of the souls he evaluates.

Unlike arbiters like Decim, who gradually develop empathy toward humans, Ginti maintains a strict emotional distance, believing that arbiters and humans should not form any personal connections. He sees any interaction outside the scope of judgment as unnecessary, even dangerous, and prefers to keep all relationships strictly professional.

While he initially becomes bored with the Death Games, his attitude shifts when he uses a remote control to manipulate and intensify the games, revealing a more sadistic enjoyment in watching how humans react under extreme stress. Ginti’s approach to judgment is far more aggressive and confrontational, reflecting his belief that exposing a person’s true nature through conflict is the most effective way to determine their fate.

Ginti plays a supporting but notable role throughout Death Parade, often serving as a contrasting figure to Decim. In one of his early appearances, Ginti is disguised as a little boy and sent by Nona to test Decim’s judgment capabilities. Decim ultimately fails the test, showing emotional vulnerability and hesitation. After Ginti reveals his true identity, he mocks Decim’s performance, and the two briefly engage in a scuffle. The fight is quickly halted when Nona intervenes and restrains Ginti, putting him to sleep while she lectures Decim on the responsibilities of an arbiter. Ginti is only awakened once they are ready to leave, serving as both comic relief and a foil to Decim’s evolving moral compass.

Later in the series, Ginti takes on the judgment of Mayu Arita, a cheerful and optimistic girl who died suddenly. During her extended stay at Viginti, Ginti offers her a difficult moral choice: she can sacrifice a stranger a person she has never met to the void in order to bring back Harada, the idol she loved in life. Though Mayu initially hesitates, she ultimately refuses to condemn a stranger and instead chooses to sacrifice herself. Even when Ginti attempts to intimidate her, Mayu stands firm in her decision. In the end, she drags Harada’s lifeless body into the elevator with her, and Ginti sends them both to the void, offering no judgment beyond that.

This arc subtly explores Ginti’s limitations as an arbiter and his inability to understand deep human emotion, such as unconditional love or self-sacrifice emotions that he dismisses or fails to interpret meaningfully. It also underscores the contrast between his rigid, confrontational style of judgment and Decim’s growing empathy.

Water Manipulation
Ginti possesses the ability to create and control water, which he stores inside kokeshi dolls traditional Japanese wooden figures. He can form the water into floating orbs and use them both defensively and offensively, manipulating them with great precision. These orbs are capable of moving at high speeds and can be used to strike opponents with force, as demonstrated during his brief fight with Decim. His water-based attacks are powerful enough to break through obstacles and are a reflection of his aggressive and forceful approach to combat and judgment.

Transformation
In addition to water manipulation, Ginti has shown the ability to alter his physical form using his water. While this ability is rarely used in the series, it implies a capacity for shapeshifting or morphing, further distinguishing him from other arbiters. This power enhances his versatility in judgment scenarios and aligns with his more theatrical and confrontational personality.

Decim
Ginti shares a strained and antagonistic relationship with fellow arbiter Decim. He often expresses irritation and attempts to provoke or challenge Decim, seeing him as too soft and overly empathetic for someone in their position. Ginti appears to view Decim as a rival, though the rivalry is largely one-sided, Decim rarely reacts to Ginti’s hostility and treats him with formal politeness. Their contrasting views on human emotion and judgment reflect the deeper ideological divide between them, particularly regarding whether arbiters should understand or empathize with humans.

Mayu Arita
Mayu is the only guest Ginti was unable to judge immediately, as her genuine and selfless love for Harada confused and frustrated him. He did not understand her emotions or cheerful personality and frequently grew irritated by her carefree antics during her extended stay at Viginti. However, after she chose to sacrifice herself to the void rather than send a stranger in Harada’s place, Ginti acknowledged her decision though coldly by sending her and Harada to the void. Despite his harshness, it’s implied that her impact on him was greater than he let on, as he later created a kokeshi doll in her likeness, suggesting a lingering sense of respect, regret, or emotional reflection.

Memine
Memine is Ginti’s cat and assistant at the Viginti, and the only companion he treats with consistent affection. He considers her more than just a pet, treating her as an equal, and becomes visibly annoyed when others dismiss her as “just a cat.” Their bond is one of the few signs of warmth in Ginti’s otherwise cold demeanor. After Ginti passed judgment on Mayu, seemingly without considering the depth of her emotions, Memine appeared disappointed in him and later left Viginti, further hinting at the emotional cost of Ginti’s rigid views and the consequences of his inability to fully understand human empathy.
