Zanka was born into the prestigious Nijiku Family and was expected to become a Hell Guard like his older sister and brother. To fulfill this expectation, he enrolled in the Central Hell Guard Training Academy in the Kamuatari District as a trainee, where he quickly rose to the top of his class. Zanka is a tall, slender teenager with a striking and meticulously styled appearance. His dark brown hair is slicked back into a mullet and accented with blond streaks that complement his piercing navy blue eyes. His unique look is further defined by his eyebrows, which are shaved into a pattern resembling three distinct lines, and his pierced ears, from which hang long, dangling tassel piercings.
