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 passing 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".
His work was discussed at Sakuga, where the presenter showed snippets of the previous cited work.
