I'm afraid the jury's still out on that one.
But I suppose I should let the boss explain the rest in person. 'Cause, honestly, I don't want to get blamed for spilling the wrong thing.
Appearance and Personality
Adonis is a slender, young man with hazel eyes and short blond hair tied in a short ponytail on the top and a red bandanna around his head. He wears a red suit with deep decolletage and black skin-tight shirt. He sports black, elbow-long gloves with red protectors on the elbows. He wears red protectors on his knees, and red boots. On his back, he has a backpack of sorts in which he keep a weapon, possibly a dagger.
When the Dead Dunes suffers from a sandstorm called God's Wrath, Adonis recruits Lightning's services to end it. After God's Wrath is dealt with, Adonis accepts Lightning as a part of the guild and reveals that his leader has been keeping tabs on her since she got off from the train at the Dead Dunes station. He takes Lightning to meet his boss, who is revealed to be Oerba Yun Fang, a former companion of Lightning.
