Between shopping sprees, giant robots, and actual fireworks, the unlikely pair flounder through their new romance and unlock their true feelings.Crafted over 7 years by the acclaimed STUDIO4°C and veteran animator Yasuhiro Aoki, ChaO is an inventive and genre-defying delight bursting with color and character.
