General Furfur serves as a professor at Babyls Demon School, renowned for his cunning intellect and strategic mind. His striking appearance features red skin, stark white hair, and yellow pupils, accentuated by zigzag horns and a flame-shaped tail. He typically dresses in white baggy trousers, a chest-covering neckcloth, geta sandals, an ankle bracelet, shoulder fire tattoos, and matching earrings.
Personality-wise, Furfur presents a relaxed and nonchalant facade, yet reveals a sharp, mischievous, and cheeky core. He takes distinct pleasure in provoking resentment, particularly from students like Jazz and Allocer, and actively manipulates situations for his own amusement. Despite this tendency, he displays genuine concern and affection for the Dorodoro Brothers, whom he personally mentored. His lineage traces back to one of the three great heroes of the Demon Valley War, cementing his reputation for formidable intelligence and tactical prowess.
Furfur's known abilities include expertise in general tactics and levitation. His relationships are multifaceted:
- He rescued and trained the Dorodoro Brothers after finding them near death on the northern battlefield, earning their deep admiration. His sudden departure prompted their return to Babyls.
- Naberius Kalego assigned him to mentor Jazz and Allocer before their second year. Initially admired by the pair, Furfur exploited them to settle his personal debts, forcing them to work at a nightclub and withholding their earnings. This manipulation fueled their lasting resentment and fear, while their struggles provided him entertainment.
- He declined a request from his former teacher Belial to tutor Rasbary, citing disinterest in Rasbary and a preference for continuing his "game" with Jazz and Allocer.
During the Harvest Festival, Furfur influenced Jazz and Allocer by directing them to a nightclub, where their simmering anger towards him became a key motivator for their efforts. He openly laughed at their failures throughout the event.
Trivia notes his inspiration from demonology: Furfur is depicted as a Great Earl of Hell in myth, associated with causing love between humans, creating storms, and teaching divine secrets. His deceptive nature and deer-like appearance in the series reflect this mythological origin.
