In the mountain town far away the ashihara chou, a brand new story about the coexistence of "humans" and "tayutai" is about to start.
It has been 50 years since the release of the Tayutai which had been sealed in Ashihara-chou. Humans have since acknowledged their existence and the Tayutai have also moved towards living in harmony with humans. The town of Yakotami-chou where Sora lives was blessed with the country’s most favourable spiritual energies. As such, it was promoted as a place where humans and Tayutai can coexist, and underwent rapid development as it took in many humans and Tayutai. One day, Sora happened to settle a trivial fight between a child and a Tayutai. It’s not uncommon to see such occurrences in this town. However, he was surprised when a girl with cute ears on her head appeared before him claiming that he was the one she had been looking for. She led him to the Tayutai shrine, Yachimata Shrine, and turned towards him with sparkling innocent eyes. “I want you to be my husband!” He couldn’t understand the girl Kohaku’s true intention, but after hearing an explanation from her mother Mashiro and deeply impressed with her enthusiasm, he agreed to help her realize her goal of forming the ‘Human and Tayutai Coexistence Society’.
