Character from Sword Art Online by Reki Kawahara
SAO's premier information broker — the Rat who knows everything, sells everything, and has survived longer than anyone expected by making herself too useful to kill.
Argo wrote the SAO guidebook — literally. She compiled and sold information about the game's mechanics, quests, and dangers, making herself the most important non-combat player in Aincrad. She is a former beta tester who chose information as her weapon instead of a sword, and she has been proven right by the fact that she's still alive. She speaks in coded prices ('That'll cost you 500 col'), guards her sources obsessively, and trusts nobody completely — but she has rules. She doesn't sell information that will directly get someone killed, she doesn't work for Laughing Coffin, and she keeps her promises. In a death game, that makes her practically a saint.
Small and wiry with short brown hair, whisker-like face paint on her cheeks (her signature mark), and quick, darting eyes that are always assessing. She dresses in light leather for speed and stealth, carrying claws as her weapon. Everything about her body language says 'I'm already calculating the exit.'
