A talking dog is a beautiful story that you should have dreamt of as a child. But if you have forgotten about it, this is a reminder of that fable story. This is the story of a dog that talks, but ordinary people cannot hear his voice.

The main character, Mametaro, is an adventurous crossbreed dog. He loves his owner, Iku-chan and his girlfriend Hanako-chan very much. However, he just cannot stand Iku-chan`s friend, Akiyoshi.

During this story, which will be told from Mametaro`s point of view, the warm days of spring are finally here. The school and the riverbank, which is actually just an ordinary neighborhood for people, seems like a mysterious world that extends infinitely to little Mametaro and his friends.
