Ogata is the director for the 'Dark Moon' series. He has changed his name from Hiroaki Date(his real name) to Ogata with the production of Dark Moon to differentiate himself from his well known father(who directed the original 'Tsukigomori'), who he has a hugh inferiority complex about.

With this new series he hopes to escape his fathers shadow by creating a better version of 'Tsukigomori' in 'Dark Moon'.
