All creatures born into this world will always have a spirit in their bodies. No matter what kind of creature it is, without exception, a spirit is supposed to dwell in it. However, Ugetsu Akira, the eldest son of a samurai family, was born without a spirit in his body in a nation called Takamagahara, and was therefore shunned by his family and eventually banished from his hometown. Three years later, Akira lives a peaceful life in the southern part of the island, far from his hometown. However, those peaceful days came to an end, and Akira took a step forward on a journey to learn more about himself.
