Grappa

グラッパ

The manager of a casino ship inspired by a ghost ship. Grappa resembles a piggy bank, but he is actually a monster that feeds on human desires. In fact, the casino he controls operates on the principle that "gold coins rule the customers", and the coins used within it possess their own intentions.
In the end, when Jing removed his desire, his true form, which appeared as a combination of a huge gold coin and an insect, was revealed, and he died after receiving a Kir Royale.
Grappa appears as a boss in the Game Boy Color games.
