Shin Oonuma

Oonuma's first appearance in anime was as an in-between animator for Berserk) as a sub-contracting employee of Office AO. He continued working with Office AO, and in 2003 made his debut as an episode director on Nurse Me! and Triangle Hearts ~Sweet Songs Forever~ under the series direction of Akiyuki Shinbo. The following year, he was invited alongside Tatsuya Oishi by Shinbo to join Shaft, and the three became known as Team Shinbo. According to Oonuma, Shinbo had invited him to Shaft due to Oonuma's understanding of digital compositing and processing, which he had showcased on Triangle Hearts. Their first project with Shaft was Tsukuyomi: Moon Phase, and Oonuma's liking of the "moe" aesthetic and "gal games" lead to him being particularly helpful to Shinbo on the series, who admitted to having no understanding of the "moe" aesthetics of Tsukuyomi. A majority of Shaft's productions from 2004 to 2009 were subsequently directed by the three, with Shinbo taking an executive role at the studio, and Oonuma and Oishi doing most of the hands-on directorial work. In 2009, Oonuma left Shaft to pursue work with Silver Link. At Silver Link, Oonuma has taken a similar role to Shinbo's executive role at Shaft. He has been involved with most of the studio's productions as either director or chief director, and has mentored or influenced several directors including Masato Jinbo, Masafumi Tamura, Takeshi Inoue, and Mirai Minato.
