After learning of the special and unique pills that the Dark Magus was able to make, Alba had an obsession with finding this person. She already envisioned that with him by their side, they would be able to go beyond what they currently already were.
She had big things planned for the Crimson Crane, to become a worldwide force that could be utilized at will, with the aim of mainly protecting the people. It's why they were wanderers and helped out in cases adhering to any faction, and it was also why they focused more on getting rid of dangerous portals than the affairs between factions and governments.
However, she had received no luck. Time after time, there were no signs of this Dark Magus, and finally, when Dame was going to introduce him to them, he was nowhere to be seen.
