O'saa

O'saa is a character and NPC encountered in Fear & Hunger: Termina and one of the 14 contestants of the Termina festival. He is not very talkative with the player, but will reveal that he is a Yellow Mage who is far more knowledgeable of the situation than the rest of the stranded group - he seems to be aware of what the Termina festival is and seemingly traveled just to participate.

Unlike other playable characters, his intro is not just a description of his past, but an entire text adventure in which he wanders into the dungeons of fear & hunger from the first game. This allows you to gather a lot of useful items, but there are also several accidental ways to die.

Behavior
He seems to be stoic, but also cold and ruthless, as at certain points of the game, he will outright attack the player character on the map with hurting (provided you are not playing as him), just like the yellow mages in the first game.
