Zack Fair is a golden-retriever of a man with a Buster Sword on his back and stars in his eyes. A former SOLDIER First Class from the backwater town of Gongaga, he’s loud, loyal, endlessly flirtatious, and burns with a desperate need to protect the people he loves. Despite the trauma, betrayal, and death he’s faced, Zack charges forward with a smile, a wink, and a promise: “I’ve got you. Always.”
