Bro is a member of the Cleaners and serves as the leader and person in charge of a team within the organization known as Team Child. He is a tall and muscular man who typically keeps his long black hair, which has blond dyed sections, tied back in a ponytail. He has brown eyes and a short, pointed beard accompanied by black earrings. His attire does not include the standard Cleaner jacket; instead, he wears a shirt that incorporates the jacket's signature design features, such as black patches and the group's symbol. His most distinctive accessory is a pale green bandana patterned with a navy blue cross-eye design, which also functions as his Vital Instrument.

In terms of personality, Bro is depicted as a calm and peaceable individual who often finds himself apologizing for the behavior of his much younger and less socially aware team members. He advocates for harmony and demonstrates a deep, paternal care for Dear, the youngest member of his team. Although Dear is not his biological child, he has taken on the responsibility of raising her and watches over her growth with great attention. He holds the belief that a parent must pay close attention to a child, as once a child sets their mind to something, they are capable of achieving great things even if a parent might initially doubt their potential. He is protective of Dear, and his dislikes include people who would seek to harm her, as well as sweets. He enjoys activities like conversations and board games.

Throughout the story, Bro is consistently seen accompanying his teammates, Dear and Guita. He was present at the Cleaners headquarters when Rudo first visited and also attended Rudo's welcoming party. His role often involves supervising and managing his team, such as when he drags Dear away after the boy makes a demand for Rudo's sweets. Bro is also involved in more serious operations, including meetings to discuss threats from marauders and vandals, during which his team was attacked and forcibly transported through a portal. He has also been present when other Cleaners received warnings about dangerous individuals. In situations where the Cleaners are under attack, Bro participates in the defense, demonstrating his role as a capable fighter within the organization. His development is closely tied to his responsibilities as a caretaker and leader, balancing the need to nurture the potential of his young charges while also protecting them from harm.
