Being a Salesperson is a roleplaying subclass in Elder Tale. One of its variants is the Saleslady subclass (lit. House Mannequin (ハウスマヌカン?), though it means the same thing).
Log Horizon: New Adventure Land[]
The Saleslady subclass is one of the subclasses that can be acquired in the mobile game. It raises the player character's ATK for the next turn and has a 12-turn cooldown.
