Ichiro Ogami was chosen to head the Hanagumi when he proved himself capable during a test of a Koubu prototype at sea. Kayama was with him during that time, but eventually Ougami was sent to work with the Hanagumi, as Kayama worked with the Tsukigumi. In the TV series, he temporarily assumed the role of Assistant Commander.
