Allocer Schneider is a demon student in the Abnormal Class at Babyls Demon School. He has a lion-like appearance with yellow fur, a spiky golden mane, and black eyes that typically hold a vacant stare. His mouth is perpetually open, revealing sharp teeth. After training under General Furfur, he begins wearing a black muzzle that conceals his expressions and styles his mane straight back into a mohawk-like shape, its color shifting to light grey. He is 16 years old, stands 173 centimeters tall, and weighs 70 kilograms. Known as the King of a Hundred Knowledges, Allocer achieves the highest academic scores in his grade, excelling in theoretical subjects. His performance earns him a rank promotion from Aleph directly to Gimel during his first year, later advancing to Daleth. He assists Professor Furcas in her research, forming a mentorship-like bond. Despite an absent-minded demeanor, he demonstrates sharp analytical skills and strategic thinking, often using complex vocabulary. He balances seriousness with playfulness, typically acting as a problem-solver. He forms a close partnership with his classmate Andro M. Jazz after they endure harsh training together under Furfur, mastering deception, disguise, and social manipulation. During the Harvest Festival, he returns a stolen item to Iruma and Lied out of loyalty to Jazz. In the Heartbreaker exam, after Jazz is captured, Allocer leads their first-year team and hides a teammate to ensure his survival. His abilities include vast demonic knowledge and transformation magic for perfect disguises. He uses spells such as La Fire, Libera, Gran, and Acceleration, and his familiar is a Smart Hawk for information gathering. He holds a grudge against Furfur yet continues using the black muzzle as a tool in his strategies. His academic connection with Professor Furcas leads to an invitation to a group date with her daughter, prompting classmate teasing. Later, Hong Linchan proposes marriage to him after a team test, leading to persistent pursuit.
