Kitazume Hiroyuki is an animator and mangaka. Sometime in 1982-1984, he founded Pack with former Bevore employees, and later in 1987 Atelier Giga. After the production failure and commercial failure of "Relic Armor Legaciam", both studios would be dissolved shortly later, after amassing a massive debt from the project. Shortly after, he would join Anime International Company (AIC) to pay off his debts. And as of 2004, he had left AIC and went freelance. He now frequently works on projects by Sunrise.
