Gamute, also known by her real name Tera Kimura, is a significant antagonist from the anime Ninja vs. Gokudo. She is the young and unstable leader of the Cracked Children, an assassin group composed entirely of underage girls, and holds the position of one of the Eight Gokudo Poles of Destruction, the elite fighters of the criminal underworld. Her nickname, the Prince of Murder, is a chilling contrast to her youthful and often childish appearance.

At first glance, Gamute appears frivolous, short-tempered, and prone to playing the fool, with a mental state that seems fractured and erratic. One review describes her as a "freaking lunatic," highlighting her unpredictable and violent nature. This facade, however, hides a remarkably calm and calculating individual with sharp observational skills. She delights in killing, specifically targeting what she calls "expensive adults," and declares herself an "ally of all broken-hearted children." This twisted sense of justice stems from a profoundly traumatic past. She is the unacknowledged daughter of Kiwami Kimura, the leader of the Gokudo, a fact he does not recognize and which is later revealed to be biologically incorrect. Her mother, abandoned by Kiwami, subjected Gamute to horrific abuse from a young age, including taping her nose and mouth shut, severe beatings, and even castration. Paradoxically, despite this cruelty, Gamute harbors an immense and pathological love for her deceased mother, speaking to her mummified remains with joy every day. Her signature look of having her hair and face wrapped in masking tape is a direct reflection of this childhood trauma.

Gamute's primary motivation is a burning resentment towards Kiwami Kimura. She views him not as a father but as the man who abandoned her and her mother, and she constantly seeks an opportunity to kill him. Her role in the story is to act as a chaotic and brutal force that escalates the conflict between the ninja and the Gokudo. She first appears in the Kabuchika district, where she helps deliver a finishing blow to the mortally wounded ninja Nodoka Matsumoto, cementing her as a lethal threat. Her personal vendetta leads her to engage Shinoha Tanaka, one of the top eight ninjas. In their first encounter, she slashes his right eye, leaving a scar, but loses her left hand in the process. This injury only fuels her desire for revenge against both Shinoha and Kiwami, whom she also blames for a subsequent bombing that nearly killed her.

Beyond her hatred for Kiwami, Gamute forms key relationships that define her actions. She shows a profound empathy for her "broken" comrades in the Cracked Children, whom she considers her only true family. Her leadership is born from a shared suffering, and she often displays an exaggerated insane facade to connect with their pain. She is deeply attached to Prima Yuka Ito, a fellow executive, as she suffers from a brain abnormality that prevents her from sleeping unless Prima co-sleeps with her. She also holds deep admiration for Hiroki Yajima, a legendary Gokudo figure whom she calls Anchan (older brother), and genuinely weeps upon finding his corpse. These connections, however, do not soften her brutality; rather, they serve as the few anchors for a mind shattered by abuse.

Throughout the series, Gamute undergoes a development that reveals her underlying tragedy. While she initially seems like a mindless killer, her more calculating and composed side becomes prominent during the attack on the Prime Minister's Official Residence, where she masterminds a plan to kill both Shinoha and Kiwami. Her ultimate confrontation with Shinoha sees her ingest two doses of the superhuman-enhancing drug Hell's Tickets, pushing her power to its absolute limit. As she faces defeat, her limbs severed, she does not curse her enemy. Instead, with her dying breath, she reveals Shinoha's true identity as a ninja to Kiwami, taking joy in the astonished expression on her father's face. In her final moments, she has a vision of an "if future" where she and her comrades are not broken, living ordinary, peaceful lives. This poignant fantasy, where she imagines a simple life with a family, underscores her deep, unfulfilled longing for normalcy and love, revealing that behind the mask of the "Prince of Murder" was a child who was forever shattered by the cruelty of the adults who were supposed to protect her.

Gamute possesses several notable abilities that make her a formidable fighter. Her primary weapon is a dual-bladed sword called W-Doss Doss, made from two short swords taped together after she lost her left hand. Her most devastating technique is the Gokudo Technique Yamai-Dare, where she uses her blade to make an incision in a target's liver and slightly displace the tissue, instantly inducing symptoms identical to end-stage liver failure. Her superhuman skills are extraordinary; she can precisely stab internal organs through gaps in muscle fibers and operate for about thirty minutes without breathing by sealing her airways with tape. Her physical prowess can be further amplified by Hell's Tickets; while her base Masacre Point is 530,000, taking two doses skyrockets it to over 10 million, granting her immense strength and allowing her to temporarily mimic the abilities of her fallen comrades.
