Zepile

Zepile is an NPC in the game. Like other NPCs (excluding sailors), he will ask you to beat a quest to obtain awards. He is most likely based off of Zepile in Hunter x Hunter.

When talked to, he will ask "I've been looking around the city for some valuables to sell. Maybe you can find me some gems." Accepting the quest, "Gems", requires you to find four different valuables around Yorknew, and the rewards are 125 cash and 1750 exp.
