Norakuro Ittouhei

Norakuro, a black-and-white dog soldier, serves in the Pōchiku Army under a strict captain. During a routine drill at the military base, the captain tests a new hot air balloon. However, nobody notices that it isn't tied down, and a strong wind carries the captain away.

Norakuro watches helplessly as the balloon drifts into enemy territory, landing in the land of the monkey army. The captain is quickly captured by the monkeys. Determined to rescue his superior, Norakuro sets off on a dangerous mission behind enemy lines.
