There are always things in this world that ordinary humans cannot see, such as souls, such as barriers, such as those with supernatural powers who live outside common sense. There are not many of them, but they have their own organization, the world they live in, and their own powerful power. So, they gave themselves a name, spiritualists.
Spiritualists can see the world that ordinary people cannot see. They are existences that transcend common sense. For thousands of years, they have maintained a balance with the souls from the underworld. However, with the birth of the owner of the "Eye of Foresight", the balance began to be gradually broken. Greed and desire have led more and more people to darkness...
