Fun fact: @ichirou_o, the head writer of Witch from Mercury, got his start in the industry as a writer. In the late 90s he penned multiple Martian Successor Nadesico, Utena, and 08th MS Team novels. The latter got him the attention of Sunrise execs—and by extension, Tomino. Ōkouchi was brought to help script Turn A #Gundam (1999-2000). He worked closely with Tomino, writing a total of 4 episodes. In fact, they worked so well together that Tomino chose Ōkouchi to oversee his next show, Overman King Gainer (2002-03), as lead writer.
