William walker is the son of a moderately wealthy couple who immigrated to America from Australia, he always enjoyed using a bow as a hobby, which comes in handy when he and his friends Iizzi and Megan ) find themselves in the middle of an otherworldly invasion (which I swear I will elaborate more on someday)

William always liked nature, and preffered to wander the woods around town rather than sit in his room and study, his parents once wanting him to attend a university, but after the invasion of earth, William instead went on to become a worshipper of Animami, gaining powers of a lycanthrope.
