In his human form, Hige is dressed in a laid-back, everyday style that reflects his easygoing personality. He wears a mustard yellow short-sleeved jacket layered over a long-sleeved dark grey shirt, pale grey sweatpants, and dark grey sneakers. Around his neck, he wears a distinctive leather collar featuring a metal plate engraved with the letter “X.”

In his true form, Hige resembles a Mexican wolf, characterized by his tawny fur and longer coat. His build is slightly more rounded compared to the other wolves, a trait that Tsume mocks by calling him “porky.” His thick, fluffy fur complements his more relaxed and well-fed appearance.

Hige begins the series with a detached and carefree attitude, often acting as the lighthearted member of the pack. His relaxed demeanor allows him to observe situations with a practical lens, such as when he tells Kiba that pride has little value if it leads to death. Despite his seemingly nonchalant approach, Hige possesses the keenest sense of smell in the group, which often leads him into unexpected situations, both adventurous and dangerous.

Although independent by nature and comfortable on his own, Hige grows more attached to the pack over time. Upon discovering that he was unknowingly manipulated to betray his companions, he undergoes a notable shift in character becoming more serious and even turning against Lady Jaguara in a display of loyalty. He also shares a close bond with Blue, and their relationship is strongly implied to be romantic.

Among the wolves, Hige is one of the more level-headed and strategic thinkers. He prefers planning over impulsive action and often relies on intuition, except when hunger distracts him. His flirtatious side and pursuit of female attention are recurring traits, but as the journey progresses, Hige matures significantly due to the hardships and relationships that shape his growth.

Before joining Kiba and the others, Hige was unknowingly under the control of Lady Jaguara. Along with his former pack, he had been brainwashed into serving her by locating other wolves and leading her forces to them. The collar Hige wears is, in fact, a transmitter that allowed him to move freely within Jaguara’s city while remaining under constant surveillance.

This collar not only monitored his movements but also suppressed his memories, causing him chronic migraines as a side effect. His memories begin to return only after the collar is damaged during a skirmish with Jaguara’s soldiers. It is revealed that at least 22 other wolves were subjected to the same treatment, all of whom were killed upon returning to Jaguara’s city.

Hige is introduced in Wolf’s Rain shortly after Kiba is captured by scientists in Freeze City. In his human guise, Hige approaches Kiba and encourages him to use the same disguise to survive, stating that pride is meaningless if it leads to death. Taking Hige’s advice, Kiba escapes the laboratory with him. Upon learning of Kiba’s quest to find Paradise, Hige though not fully convinced agrees to accompany him.

Upon arriving at the Lost City, Hige exhibits an uncanny familiarity with the surroundings, though he is unable to explain it. Unknown to him at the time, he had previously been in the city but had his memories suppressed by the collar around his neck. He begins experiencing severe headaches whenever he tries to recall specific details or thinks too deeply about his past. When he sees a statue of Lady Jaguara, he is struck by an overwhelming migraine and instinctively flees.

Hige is later cornered by some of Jaguara’s men, who identify him as “Number 23.” Oddly, they leave without harming him, causing Hige to question why he was spared. He soon realizes that he is being watched throughout the city, likely via surveillance systems tied to his collar. In a panicked attempt to escape, Hige is found unconscious by Blue, who informs him about Kyrios and the destruction caused by Jaguara’s forces. The two attempt to flee together.

Realizing the collar is the source of his migraines and memory loss, Hige asks Blue to remove it, though she is unable to. Their escape is interrupted by two of Jaguara’s soldiers, one of whom inadvertently shoots off the collar. Freed from its influence, Hige escapes the city with Blue.

• Kiba: Hige and Kiba form the first meaningful bond among the wolves. Hige approaches Kiba with a friendly and nonchalant attitude, and despite their differing personalities, Kiba gradually comes to accept him. Their mutual trust deepens as the journey progresses, and after the revelation of Hige’s past ties to Lady Jaguara, Kiba is the first to offer him understanding and forgiveness.

• Blue: Hige and Blue share the most clearly defined romantic connection in the series. Initially an antagonist, Blue served as Quent Yaiden’s companion and helped him hunt wolves, believing them responsible for the destruction of her home in Kyrios. After encountering Cheza and the pack, Blue’s dormant wolf blood is awakened, leading her to abandon her previous beliefs and join the quest for Paradise.

  Among the pack, she grows closest to Hige, and their relationship develops into a deep emotional bond. Despite doubts about whether Paradise will accept her due to her half-wolf, half-dog nature, Blue remains devoted to Hige and promises to stay by his side regardless of the outcome.

• Tsume: Hige and Tsume often clash due to their contrasting personalities. Tsume’s blunt and often critical nature is met with casual indifference by Hige, who tends to brush off sharp remarks. Though their relationship is marked by friction, there is still an underlying respect between them as fellow members of the pack.

• Toboe: Hige takes on a big-brother-like role toward Toboe, frequently offering advice and guidance. The two are often paired together during tasks, and Hige shows a protective and mentoring side when interacting with the younger wolf.

• Cheza: Like the other wolves, Hige is drawn to Cheza as the Flower Maiden, recognizing her as the key to finding Paradise. He expresses a sense of duty in protecting her, though unlike Kiba, he clarifies that his feelings toward her are not romantic, once commenting that she is “not his type.”

• Lady Jaguara: While Hige never interacts with Lady Jaguara directly, she plays a central role in his past. Under her control, Hige was unknowingly used to locate other wolves, with a collar serving as both a tracking device and a means to suppress his memories. Though unaware of her influence at first, Hige eventually breaks free from her control and turns against her regime.

Hige’s name is written in katakana as ヒゲ, which translates to “whiskers” in Japanese. The name reflects both his wolf identity and his slightly rugged, unshaven appearance in his human guise. It also complements his relaxed and playful personality, distinguishing him from the more serious members of the pack.
