Lupin the Third: Princess of the Breeze
What they share
Theysit in Action / Adventure / Animation territory. If that's the register that drew you to Donten: Laughing Under the Clouds - Gaiden: Chapter 1 - One Year After the Battle, the second film will land in a comparable space — through a different lens.
What Lupin the Third: Princess of the Breeze is
A TV movie that knows exactly what it is. Lupin and Jigen suddenly have to look after a baby, even as a sky pirate named Yutika tries to steal their score. It all involves a city-state's treasure and some very cross authorities.
