The story of Ji Nanyue who was reborn as a mermaid princess and Sesshomaru.
I would like to dedicate this document to "InuYasha", which we have loved and followed for so many years, and to Shaden, who made me fall in love at first sight.
This happened 400 years after the end of InuYasha's story. Sesshomaru had established his own Inuyasha Kingdom of the West and became the emperor of the West.
The human world and the demon world have long been separated, and each has its own independent time and space and has begun to develop into the future. The once innocent and kind-hearted little girl Suzu has grown up and became the Queen of the West. Under Sesshomaru's concealment, she relied on the mermaid heart to stay young forever. Sesshomaru thought that in this way he could keep Suzu by his side forever, but the curse of the mermaid clan could not make his beautiful wishes and promises come true.
