Demnar Kitako Jr. serves as both teacher and lifelong caretaker for Wistario Afam, a role he has held since Wistario's birth. He operates within the harsh environment of the Radonitsa Colony, a remote penal settlement near Venus where inhabitants lack formal identification and colonial development was historically neglected compared to Mars. Beyond education and guardianship, Demnar secretly maintained the Gundam Hajiroboshi mobile suit for many years, ensuring its operational readiness without Wistario's initial awareness. While presenting a strict and severe visual demeanor, his actions consistently reveal a contrasting tendency to pamper and indulge Wistario.
