Sol

Sol and Mani are Twins as old as time itself, these two act as the gatekeepers for the traversal between the three different realms. It is speculated that these two are higher powers above the 3 main deities, however little is actually known about these two. Never showing any emotion, as if physically uncapable of having emotions, the twins simply exist in this world.

Despite likely being the creators of the Unniverse, these two instead watch everything take place and never interfere. It is unknown why they do this, however it is implied that they are the ones who granted Shizuka the ability to open the 'gates' to access the other planes without the permission of the 3 Gods.
