Nobody talks about this one. Two androids baking pastries while searching for their vanished creator sounds absurd, and it is, but the show treats it like the most sincere thing happening on screen. The quietness matters more than the premise: these sisters just want to make something that brings people happiness, and they're willing to chase the horizon to figure out why their Master needed to leave to find it.
Choco and Naruto are android sisters with human hearts, built by a mysterious figure known only as Master to help bake CHOCONARUTO, a pastry said to bring happiness. When their Master disappears in search of true happiness, the two find they cannot manage the pastry on their own, so they head out on a journey to find him. The six-episode OVA plays their quest as comedy with an ecchi streak.
