Jack

Species: Labrador Retriever

Jack lives in Room 701 of the dormitory and is a friendly rival to his childhood friend and partner Legoshi, with whom he constantly hones his skills. He is a 17-year-old male, born on December 22nd, with blood type O. He stands 167 cm tall, weighs 55 kg, and is left-handed.

As a member of the "dog" species, which were created through selective breeding from wolves, Jack has a mild temperament with little aggression. His cheerful, energetic, and friendly personality makes him easily approachable and garners the trust of those around him. On top of that, he is exceptionally intelligent and boasts top-tier grades at school, earning him the admiration of his peers as an outstanding student.

However, during his childhood, Jack struggled with a deep sense of inferiority stemming from his origins as an "artificial" species, feeling conflicted admiration and jealousy toward the "real" wolves before the breeding process. Because of these feelings, he used to get into frequent quarrels with Legoshi. Over time, however, they gradually grew to understand each other, becoming the closest of friends. Nowadays, Jack's considerate and caring nature is especially evident in how he looks out for Legoshi, who is often misunderstood by others.
