The bustiest and curviest of the Sisterhood of Trinity High School. A hard-working Sister of the Sisterhood. Hinata possesses physical strength incomparable to the other Sisters, allowing her to easily do heavy-lifting tasks that would require the strength of two or more Sisters. She is also quite clumsy, often forgetting to do simple yet important things such as keeping the door locked. Her main job is "Managing the supplies in the cathedral" but she usually do more than that.
