Huey is one of many NPCs that doesn't give client orders or (seemingly) appear anywhere in the lobby/shopping areas, but sometimes shows up in event tablets or random code: whatevers.
That's because he's part of the Six-Awns-Equilibrium or whatever you want to call it (六芒均衡/Rokuboukinkou)
Being the most elite ARKS members would mean he's too busy to be seen there :/
