Naoki Hamaguchi's involvement was already highlighted in the recruitment notice, where he talked about how he would be the development manager overseeing the management of the internal development staff. Mobius also didn't have a standard "director" role as far as they've made public, and his role was also 'Project Lead", a more management-centric role than a creative lead one. He was previously a lead programmer on all 3 FFXIII titles.
