Lamila is the Guardian Character of a wealthy prince named Shuraiya. He was created from Shuraiya's wish to be a strong king.
His appearance resembles that of Shuraiya's father. This is probably from Shuraiya's dream to grow up into a strong king.
Ramira is calm and level headed. He doesn't like Shuraiya's arrogance and grandiose hopes, but he learns to tolerate his master after he is purified.
He was turned into an X-Egg when Shuraiya lost himself to a pendant that was created by X-Eggs' energy (that resembled the embryo), but before he had time to hatch, he was purified by Amu.
