Description
Hiiragi Nono is a main character in the anime BBK/BRNK: The Gentle Giants of the Galaxy. He is a sixteen-year-old boy with green eyes and short, spiky brown hair that reaches his ears. His typical appearance includes a tie and a jacket, and he often has one eye showing through his hairstyle.

In terms of his background and role within the story, Hiiragi is identified as one of the legs of the colossal sentient weapon known as Oobu. As a Buranki wielder, he is part of a group of young individuals who can control these powerful entities. Hiiragi is portrayed as an antagonistic and confrontational member of the group. His personality is notably harsh; he is openly hostile and expresses disdain for many people. For instance, he displays a particular hatred for a woman named Horino, a former Buranki user who gave up fighting, and he is openly critical and rude, once commenting that a home-cooked meal was indelicate.

Hiiragi's motivations are heavily tied to his personal history and his goals regarding Oobu. He is intensely focused on obtaining the heart of the Buranki from the protagonist, Azuma. This desire leads him to be openly confrontational, and at one point, he attempts to take the heart by force after verbal arguments fail. The reasons for his aggressive behavior are rooted in his past; his father suffered a difficult fate after Buranki users fell from grace, suggesting that personal loss and a desire for power or control drive his actions.

His key relationships are defined by these conflicts and his role within the group. He is later revealed to be in a relationship with Kinoa Ougi, another member of the Buranki wielder group. However, his primary dynamic is one of opposition to Azuma, whom he views as an unworthy leader. Despite his hostility, the story explores the necessity of harmony among the wielders, as their Bubuki are all parts of the same Buranki, Oubu. This forces Hiiragi into a situation where he must learn to cooperate, even if reluctantly.

Regarding his development, Hiiragi begins as a character defined by his cynicism and aggression, but the narrative gradually reveals the vulnerabilities beneath his abrasive exterior. His backstory concerning his father provides context for his mistrust and his desperate need to secure the heart. As the group faces external threats, he is challenged to move beyond his individual vendettas and find a degree of unity with his fellow wielders, though he remains a consistently edgy and difficult presence.

In terms of notable abilities, as a Buranki wielder, Hiiragi can control his specific part of the giant weapon Oobu, functioning as one of its legs. The exact nature of his combat skills is tied to this role, but his primary defining trait is his aggressive personality, which often leads him into direct physical confrontations with both allies and enemies.
