In his role as producer, Iwakami took a mostly hands-off approach. Because Puella Magi Madoka Magica is an original series rather than an adaptation of an existing work, his main goal was "coming up with a high-quality piece of entertainment". After helping to recruit the staff, he allowed them freedom to develop the content of the story, providing minimal guidance. After viewing the character designs that Aoki created, he was sure he could trust the creative talent of the team. In an interview with Anime News Network after the series finished airing in Japan, Iwakami said, "I don't matter much; it's up to those talents to do their work. If something comes to a stand-still I might intervene, but they did an excellent job and I was very happy seeing the results in episode one."
