Jack is an NRC student belonging to the Savanaclaw dorm. He is a tall, muscular, swarthy-skinned young man with platinum blonde hair and golden yellows. He has wolf ears and tail with white fur due to his half-wolf nature. He is someone who seems rather cold and distant with the other students, pretending that he can manage on his own. He is, however, considerate and careful with people he considers his friends, being able to feel quite comfortable showing them his wolf form.
