An unidentified phantom beast that appeared at the same time as the heroes are sealed. Because it uses a different language than those in Cray, it is said that it may be a resident of a different dimension.
The new born "Shadow Paladin", rebuilt by the hands of Blaster Dark, begins to work behind the scenes in order to make the United Sanctuary a better nation despite not being the regular army. However, the newly built organization is brittle due to the Shadow Paladins being thrown into disorder when he was sealed, resulting in many warriors to leave temporarily.
In addition, there are only very little Shadow Paladins that joined the "Gold Paladins" who were touted as warriors who liberated the heroes. The sealing of the heroes, the knights who were at the verge of collapse, the mysterious newcomer, has thrown the "Shadow Paladin" into a downright confusing state.
