Backstory:
I'm sure you're wondering why he hates dark guilds so much. The reason is that he used to be a normal wolf pup until his family was killed by a dark guild. The dark guild that killed his family than experimented on him. They planned to use him as a weapon but he refused and escaped. That's when he decided his name would be Firework
Not to long after that, Firework met Bryan after he helped Firework get out of a bear trap. The 2 of them became close friends, and Bryan introduced him to his brothers, Mario and Mitch. Firework became friends with them, but was still closer to Bryan. One night, when everyone except Firework was asleep, he made a promise.
That promise was that he would protect Bryan from any dark guilds that appear.
