Person: Nieta Hideo q5i26

Iso Mitsuo was born 1966 in Aichi Prefecture, Japan. He is a Japanese key animator, designer, anime screenwriter and director. He is also known under the name of Odagawa Mikio (小田川幹雄) and Nieta Hideo (贄田秀雄)

His work mainly includes key animation starting in the late 1980s. Iso is known for his offbeat key animation in the prologue of Gundam 0080, large portions of Asuka's battle in The End of Evangelion and the first half of Ghost in the Shell's tank battle. He also did some design work and worked on visual effects for Blood: The Last Vampire and RahXephon. Iso has co-written an episode of Neon Genesis Evangelion ("Liliputian Hitcher") and wrote, directed, and largely animated the RahXephon episode 15 "The Children's Night". He wrote and directed the current TV series Dennou Coil.

Mitsuo Iso is known for his jerky yet detailed animation, full of dense sophisticated motion. He refers to his own style as "full limited" or "full 3-frame". In traditional animation, animation with a drawing count below one drawing every two frames (or "on twos") is considered limited animation. Working on threes and fours, Iso draws every keyframe without ing his work to an in-betweener, allowing him full control to create the most detailed motion possible with the fewest number of drawings, hence the term "full limited".

Dennou Coil, along with three other animation works, was awarded an Excellence Prize along at the 2007 Japan Media Arts Festival. At the seventh annual Tokyo International Anime Fair, Dennou Coil won top honors in the Television category. At the 46th Japan Science Fiction Convention, Dennou Coil was the only winner of the Seiun Award in the media category which covers all non-literary works, such as movies and TV series.

Odagawa Mikio is an alias of Iso Mitsuo.
