Sakura Sugai is a 16-year-old female with distinctive violet hair, brown eyes, standing 168 cm tall with measurements of 82-57-84. As one of six priestesses-in-training at Saienji Temple representing the Hungry Ghost Realm, she possesses the supernatural ability to consume any amount of food without ever feeling full or altering her physique.

She wields authority as president of the student council at East Tousen High School, driven by a keen interest in politics and enforcing rules, reflecting a sadistic streak for controlling others. This extends to her "Dr. Sakura" website, where she offers advice to the troubled but takes visible pleasure in publicly ridiculing their problems, suggesting a complex self-awareness.

Sakura is the fiercely protective older stepsister of Hinata Sugai, harshly punishing anyone who harms her. She routinely manipulates fellow temple trainee Ikkou Satonaka into performing tasks for the temple, her sister's benefit, or her own personal gain. Beneath this harsh and sadistic exterior lies a capacity for genuine concern, particularly for Hinata, hinting at underlying compassion.

She also serves as an exorcist, participating in the temple's spiritual duties alongside the other priestesses. Her established roles within both the temple and the school remain consistent across documented appearances.
