The events take place one year after Seiken Densetsu 3. The story takes place in a world called Celestial Island where souls stay before being judged for their actions in life. If you were a good person in life, you will go to heaven, otherwise you will pay for your actions in hell. In this world that is a mixture of past, present and future, souls await their destiny, whether good or bad. But there is a soul who denied his destiny, and wants to leave this world before he is judged for the actions he committed in life. And now the world of souls is in great danger, as is the world of the living, as an ancient evil that was once banished wants to return to life.
