Keiko Sasa

Sasa worked as an inbetweener across four Dragon Ball episodes (132, 139, 146, 153) in the Piccolo Jr. Saga, a tournament arc known for its escalating martial arts choreography and character transformations. Episodes like Hotter Than Lava and Goku's Trap demanded precise inbetweening to translate key animators' dynamic poses into fluid movement. Her work extended to Dragon Ball Z, where she continued supporting the franchise's expanding action sequences.

Inbetweeners form the structural foundation of anime production, working from key animation layouts to fill in dozens or hundreds of intermediate frames. Sasa's placement on tournament and transformation-heavy episodes reflects the studio's confidence in skilled inbetweeners to handle demanding action material, where smooth transitions between poses are crucial to audience engagement.
