Chapter 1

The world has become divided since the 21st century. Humans and mythical creatures constantly fight for the title of the 'dominant species'. After many battles, humans have retreated into towns of their own where few creatures join them in harmony.

His accomplice, Daichi, is making a journey to his hometown after years of being out of contact. They travel together and share memories, tears, and stories on their trip. Slowly, the two notice feelings arising for one another.

Each fights for different reasons, but never leave each other's side during their long adventure.
