Cursed Child: Those from the Far East may have heard tale of a child born in a distant mountain village who was despised by the Kami. The natural talents others possessed were absent within him. Rumors spread of the child being offered as a sacrifice to an enshrined ‘god’ near to the village. Though a decent amount of time has passed since then, the appearance of the child in the tale matches up well with Yozora's current appearance.
Overwhelming Menace: When Yozora began to make a name for himself within the Far East, it was accompanied by a path of bodies. The man often took part in tournaments and similar activities, some of which were meant to the be non-lethal - yet the loss of life still occurred.
Registered Adventurer: Upon arriving in Ul'dah, Yozora took up the mantle of an Adventurer. The freedom of the job lends itself to the common desire to do as one pleases. Most typically, Yozora has accepted commissions to hunt dangerous monsters or face forces that would normally overwhelm a single adventurer.
