Description
Cislo's journey began at Goodwill Ridge orphanage before transfer to the Lambda 7214 facility. There, painful experiments granted him enhanced physical abilities and instilled a profound hatred for demons. Norman rescued him during Lambda's destruction, securing Cislo's unwavering, lifelong loyalty. Cislo consistently refers to Norman as "boss" and serves as a core member of his resistance group alongside Barbara, Vincent, and Zazie.

Physically, Cislo is a muscular teenager standing approximately 170 cm tall. His short black hair features a distinctive grey or white "X" pattern. Multiple piercings stud his ears. He favors practical attire: overalls or cargo pants paired with a tactical vest, gloves, and boots. The Lambda identification brand is tattooed visibly on his left chest.

His personality blends fierce vengeance against demons with deep loyalty and emotional vulnerability. While driven by statements anticipating "wiping out all those demons," he exhibits a calmer, more analytical side than Barbara. This allows him to support comrades and perceive Norman's internal struggles. Despite his imposing build, he is prone to open displays of emotion, including tears. His hobbies include dedicated weightlifting and weapon training.

He first appears aiding Norman in rescuing Emma and Ray from a demon. Later, at Norman's hideout, he interacts with them, sharing stories of Norman's exploits and expressing urgency to liberate their families from the farms. Though initially surprised by Emma's pacifist stance towards demons, he accepts it, trusting Norman's leadership when reassured their core mission remains. He actively participates in attacks on demon facilities, observing the destruction of one village firsthand.

A significant shift occurs when Norman abandons the genocidal plan. Cislo, noticing Norman's distress, listens to his change of heart and understands the decision. He later explains this shift to Vincent, demonstrating growth beyond blind vengeance. Encounters with demons like Mujika visibly unsettle him, provoking discomfort and guilt over his previous indiscriminate hatred.

During the assault on Grace Field House to liberate children, Cislo utilizes hot-air balloon decoys and participates in the aerial attack. He collaborates with Emma to hack communication systems, facilitating their coordinated efforts. He is present during the final confrontation resulting in the caretakers' surrender.

After escaping to the human world, Cislo exhibits concern over Emma's disappearance. Over the next two years, he attends school. He experiences profound relief upon reuniting with Emma in spring 2049, despite her memory loss. Later glimpses show him wearing a sports uniform and a prosthetic right leg, suggesting involvement in track and field.

In combat, Cislo wields nunchaku proficiently against demons, a weapon employed during raids on factory farms. His fighting prowess is noted as superior to Barbara's, making him a valuable asset in Norman's operations.

His defining relationship is unwavering devotion to Norman, viewing him as his savior. He shares a close bond with Barbara, rooted in their shared history at Goodwill Ridge and Lambda; he often acts as a stabilizing influence on her volatile temper. While initially wary of Emma and Ray due to their differing views on demons, he acknowledges them as Norman's cherished siblings.

His birthday is April 30, making him a Taurus, and his favorite food is steak. His name, of Polish origin, means "to oppress a bully." Official sources indicate his character draws inspiration from Bartolomeo in *One Piece*, reflecting similar fanatical loyalty. He and Barbara were randomly selected for transfer to Lambda 7214.
