The subject matter is the old Japanese folktale "Momotaro."( Momo means peach)
The story is about Momotaro, who was born from a big peach, who grows up and sets out with a dog, a monkey, and a pheasant to defeat ugre who do evil to humans on Ogre’s Island.

In this work, I've used this story as a base, dramatized it, and created another tale of Momotaro.
