Numachi Rōka

During her middle school years, Numachi Rōka was a rival basketball player who competed with Suruga Kanbaru. She was known for her distinctive "swamp defense," earning her the nicknames "Toxic Swamp" and "Unjumping Swamp." However, during a game, she seriously injured her left foot, which brought her playing career to an end. Afterward, she did not advance to high school and instead lived as a part-timer. Due to her foot injury, she was unable to secure stable employment and is currently nearly jobless.

Numachi Rōka appears in works such as "Suruga Devil" and "Rōka God." In episodes like "Shinobu Time" and "Hitagi End," only her name is mentioned. Her appearance features messy brown hair, which is rare in her rural town, and she is always seen in a tracksuit, walking with crutches. She speaks at a slow pace. Numachi Rōka uses various aliases, such as "Devil-sama" and "Swamp God," and runs a consultation business in several locations. She has crossed paths with Kaiki Deishū multiple times after nullifying his setups. During their first encounter, clients destined to meet demons and the future were entrusted to her, a job originally belonging to Kaiki Deishū.

A surprising fact is that after transferring schools, Numachi Rōka actually committed suicide, and the figure seen in the series is her ghost.
