Cislo grows up at Goodwill Ridge with Barbara before both are shipped to Lambda 7214. There they undergo experimental procedures intended to enhance human subjects.

Norman eventually leads an uprising that destroys Lambda and frees Cislo, Barbara, Vincent and other surviving subjects. Cislo thereafter becomes one of Norman's closest subordinates as they construct a new refuge for escaped farm children.

He participates in Norman's campaign against demon society and initially supports the plan to eradicate the demons. When Emma challenges Norman's strategy, Cislo remains loyal to his leader while gradually confronting the consequences of the campaign.

Cislo later fights alongside his companions during the struggle surrounding the demon capital and Grace Field, surviving the conflict and eventually reaching the human world with the other children.
