Trish

Biography
Trish maintains a healing fountain at which the party can heal, generally found in every dungeon, in each of the Persona 2 games.

Despite her sweet-natured appearance, Trish is notorious for being selfish, greedy, and charging outlandish prices for her healing services. While restoring in town generally costs a few thousand yen, Trish tends to charge a few dozen thousand.

Should the player refuse, she'll generally tell them to go and die for all she cares.

Her namesake is used in Persona 3 as the hostess of a television show called 'Who's Who' in which characters from the prior Persona games are given short biographies on.

While it's unlikely to be Trish herself, it's a potential reference.
