Bruce teaches at the World Ninja Association Academy alongside colleagues like Amy and Daisy. He has a tall, muscular build, light brown hair, and light purple eyes usually hidden behind pointed sunglasses. He wears a standard light blue teaching uniform with white stripes on the sleeves and sides, bearing the WNA insignia on the left chest.

Bruce radiates high energy and compassion, adopting a fatherly approach toward students, though this attitude isn't always returned. He habitually uses puns in conversation to amuse others, a tendency that often causes dismay among students and staff.

His academy responsibilities include administrative tasks like distributing student ID cards and delivering foundational ninja history lectures during orientation. He also organizes and announces extracurricular events, such as a ninja extreme skating competition. When initial student disinterest left the academy without a representative for this event, he assigned Emma as the participant and Burton as her helper. Later, when Emma fell ill, Bruce substituted Burton in her place.

Bruce possesses a specific aversion to pumpkins stemming from childhood trauma.

In combat, Bruce shows significant determination. During an engagement against a formidable opponent called Gumdiva, he persisted in attacking despite clear disadvantages. His refusal to retreat inspired allies to keep fighting and resulted in critical damage to the opponent's leg, enabling another combatant to secure victory.

His absence from the academy prompted other staff members to unconsciously imitate his habitual pun-making, revealing his subtle impact on the institutional environment.
