Description
Gueira is a character from the anime Promare: Lio-hen, where he serves as a leading general of the Mad Burnish, a group of people who can control fire. Before the events of the story, he and his close comrade, Meis, knew each other and jointly led Mad Burnish. In the prequel Lio-hen, Gueira is depicted as one of the group's original leaders before the arrival of Lio Fotia.

In terms of appearance, Gueira is a tall and slender young man with messy red hair and matching red eyes. He has a slight tan and a tattoo near his left shoulder that reads "雷刃" which means "Lightning Blade". His typical clothing consists of a light blue shirt worn under a black leather jacket, black pants with knee pads held up by a white studded belt, and black boots that resemble Lio's. When he activates his Burnish powers, he transforms into a much larger and more muscular armored form. This monstrous armor features a large chest, several red and pink segments, two horns, and a helmet with green-tinged teeth. The two horns on his armor are an indicator of his power level.

Personality-wise, Gueira is known for being fiery and impulsive. He has a strong tendency to voice his opinions and emotions outwardly, a trait that can occasionally get him into trouble. Despite his aggressive demeanor, he cares deeply for his fellow Burnish, which is shown when he and Meis rescue a newly manifested Burnish named Thyma and attempt to calm her fears about her new condition. He shares a mutual distrust with his comrades towards authorities like the Foresight Foundation and Freeze Force, believing they mistreat the Burnish, which motivates many of his actions. He is also self-sacrificing and willing to put himself in danger for the sake of others, especially his leader, Lio.

Gueira's motivations are driven by the protection of the Burnish people. He fights against the systemic oppression they face, which is enforced by groups like the Foresight Foundation. Before Lio's leadership, he and Meis conducted aggressive, thoughtless raids that would sometimes create more problems for the Burnish. However, he ultimately desires a safe place for his people to live freely without persecution.

His role in the story is that of a steadfast lieutenant. Initially a co-leader, Gueira quickly recognizes Lio’s strength and superior strategy. After Lio rescues him, Meis, and other members from Freeze Force, Gueira accepts Lio as the new leader of Mad Burnish, a position he respects deeply. From that point on, he acts as Lio's protector and a key enforcer of his will, participating in dangerous infiltration plans and engaging in direct combat against their enemies. He and Meis are often the ones carrying out Lio's commands on the front lines.

Key relationships define much of Gueira's character. His most important relationship is with Lio Fotia, whom he and Meis refer to as "boss". Gueira holds immense respect for Lio, agreeing to his schemes and even sacrificing himself so that Lio might escape danger. His loyalty is absolute, and he is willing to die for Lio's cause. Equally significant is his partnership with Meis. They have worked together since before the events of the movie and always pair up for missions. Their similar outfits, complementary tattoos Meis's tattoo relates to wind, while Gueira's relates to lightning and their coordinated fighting style highlight their long history and deep trust. According to staff commentary, with their tattoos of Japanese gods, they are meant to act as Lio's protectors. He also shows a caring, protective side towards Thyma, a young Burnish woman, from the moment she awakens to her powers.

Throughout the narrative, Gueira undergoes development from a reckless leader of a lawless gang into a disciplined and loyal soldier for a greater cause. He initially questions Lio's refusal to kill their enemies, believing in more direct and violent retaliation. However, he comes to understand Lio's philosophy that unnecessary killing would only bring harsher crackdowns on the Burnish, and he follows Lio's more strategic and merciful approach. His journey culminates in a final act of self-sacrifice, where he and Meis hold off the forces of Freeze Force to ensure Lio's escape, showing how his loyalty has grown beyond mere survival to a profound commitment to his leader and their shared dream.

Gueira possesses notable abilities as a Burnish, which include generating and manipulating fire. His primary combat ability comes from summoning his large, monstrous Burnish armor, which grants him immense physical strength and durability in battle, making him a powerful frontline fighter. Outside of his powers, he is depicted as an agile individual who rides a motorcycle named Miami. Additional trivia notes that he has an interest in football but was considered physically unfit to join teams as a child due to a weak constitution, which is why his Burnish armor is so large in comparison to his actual slender frame. It is also noted that he cannot eat hot food because he has a very sensitive tongue, described as a "whale tongue".
