Explanations

The being forming the bodies and minds of all those people is only a magical power that one day found out that it can exist as a human being. For it cannot hold one of the forms for very long, it needs to change after some time. All of them have a special power inside, that they can use in different ways. The female characters cannot hold much of that power, because their bodies and minds are too weak. For Seira was the first person that the magic power formed to have a body, he is the most powerful of them. Hikari on the other side, being still so very young, would destroy herself by using the power of the curse.

Each of the characters has a different personality. They all do not know from their first appearence who they are and what they are, only a name that is on their minds. It can happen that they switch to another person when you are just talking to them. That is the time when the body becomes too weak to hold the power of the curse any longer.
