Marbas F. Yabashi
Yabashi is related to Marbas (probably a cousin, since Marbas refers to him as "son of a relative") and is in his first year at Babyls. They haven't interacted yet, but Marbas seems to like him, asking Iruma to look after him if they meet. [3] Yabashi may have a less positive view of Marbas, as Marbas comments: "Well, there's my relative... but I don't think he'd like to meet me." [4] when asked who he would like to face during the Heartbreaker exam. This may also be due to Marbas's specialization in torture and the exam pitting teachers against students.

Instruments of torture: Marbas possesses various instruments of torture, ranging from large pincers to electric shocks.
Centipede Stinger: A giant centipede with an enormous stinger that can penetrate a demon's spinal column and wing root, destroying all five senses and paralyzing it. The effects are treatable, but the experience is traumatic.

The Art of Torture: As a master of the arts of torture, Marbas knows various ways to torture any demon, from "simulated drowning," "electric shocks," and "intense pressure." His knowledge is so vast that he can even paralyze his opponent through a slow and painful process.

Marbas appears calm and gentle, not offering many opinions on what others say and agreeing that he has an ordinary appearance. The author described him as a caring demon, but these feelings are important in the context of the study of torture. Marbas possesses a darker side, as demonstrated when Atori is captured by Sullivan and the professors. Despite being a kind demon, Marbas seems enthusiastic about the possibility of torturing Atori.

Marbas is a simple-looking demon with straight, chin-length black hair and two black horns. He is usually seen wearing the standard Babyls teacher's uniform.

Marbas March is a teacher at the Babyls Demon School. Among the younger teachers, Professor Marbas teaches the Arts of Torture.
