Jack Howl

Jack Howl is a first-year student in Savanaclaw. He is a tough delinquent who strictly adheres to hierarchy of power and strives to increase his own strengths. He dislikes associating with others.

Appearance
Despite being a first-year student, Jack has an incredibly big and tall body and is bulky. He has silvery-white hair with golden-brown eyes. Jack possesses both wolf-like ears and a tail, the same color as his hair. Like the other residents of Savanaclaw, he wears the Savanaclaw uniform.

Personality
At first, Jack seems rather cold and distant, not relying on the help of others and claiming to be able to handle things alone. Jack also has a strong sense of justice, even betraying his own dorm during the sabotage of the Magical Shift Tournament done by all members of Savanaclaw but him. As the story progresses, Jack has been shown multiple times to be surprisingly intelligent, being able to guess Azul's real form in the water just by Leona's nickname "octo punk" for Azul, and he knew what Floyd's unique magic did when he and the others got attacked by the Leech brothers.

Jack does not like to be indebted to others.

Jack has shown to have a good memory.

Unique Magic
Jack's Unique Magic is called "Unleash Beast" (, Anrīshu Bīsuto; lit. "Silence-breaking howl of a moonlit night"). It allows him to transform into a huge white wolf.

According to Professor Crewel, transforming into another creature without using a potion is special, extremely advanced magic.

Trivia

 * Jack seemingly has no correlation to any character from the Lion King franchise. His depiction characterizes him as having a wolf-like personality, yet no wolves exist in the Lion King franchise, nor do any antagonist characters with white fur.
 * He may be named after Jack London, author of the novel White Fang about a wild white wolfdog.
 * Walt Disney Pictures produced a film based on the novel, although it was live-action rather than animated.
 * He has a younger brother and sister that are also sporty like him. He also mentioned that they're able to play tag for six hours straight without getting tired.
