Abyss Razor, a third-year Easton Magic Academy student, serves as Magia Lupus's Second Fang—ranking directly beneath Abel Walker as the group's second-strongest member. Born with the "Evil Eye," a condition replacing his right eye that nullifies magic within its gaze, he endured severe persecution. His family imprisoned him in their basement, and his mother attempted to strangle him. Abel Walker ended this isolation by accepting him, forging Abyss's fierce loyalty. He conceals his left eye with bandages and initially wears a white wooden mask featuring purple cheek markings. When destroyed, the mask reveals his light blue ponytail, left-side bangs, and two jagged magic marks beneath heterochromatic eyes: a blue right eye and a yellow left eye with a red sclera and black pentagram. His attire is Easton's standard Lang House uniform—black shirt, white tie, white robe with purple-tipped sleeves, black pants, and brown shoes.

Abyss wields a sword integrated with his "Acceleraise" magic, generating blue arrows for high-speed movement. Techniques include "Acceleraise Sphere" (encircling targets with arrows for multi-directional strikes), "Acceleraise Boost" (amplifying a target's speed), and "Acceleraise Secondth: Force Field" (a Secondth-level spell draining opponents' speed in a circular area to enhance his own). His wand is hidden in the sword's handle. As a double-liner, he wields exceptional magic power, enabling Secondth Magic without artificial aids. The Evil Eye's magic-nullification remains central to his abilities, alongside proficiency in Broadcasting Magic to project remote events.

Socially inept around women due to past isolation, he stammers or avoids conversation. Though pessimistic, he channels his craving for usefulness into unwavering devotion to Abel. He prays to Abel's photo, prioritizes Abel's safety over his own life—intercepting Cell War's fatal attack—and shares a room with him. After battling Mash Burnedead to rescue kidnapped allies, he considers Mash his "first friend." He distrusts Dot Barrett and Cell War while avoiding Lemon Irvine.

Post-Magia Lupus Arc, he aids Mash's group during the Tri-Magic-Athalon against Walkis Academy and observes the Divine Visionary Selection Exam. Trivia notes: he exclusively drinks black coffee for breakfast, cuts his own hair, enjoys onigiri and the card game "I Doubt It," ranks third in Easton's "most handsome" poll, and practices to improve as Abel's "horse" during exams.
