There are many NPCs to interact with in Shin Megami Tensei V and one of them is Gustave, the Shopkeeper. This How to Visit Gustave Guide will tell you how to reach his merchant of the Netherworld.
In order to reach Gustav in the Netherworld, you must go to Cadaver's Hollow which is one of the locations you will be able to teleport to from Leyline Founts. At Cadaver's Hollow you will be able to purchase consumable items to heal your party, revive fallen members of your party, and damage enemies. Providing the price is right, Gustave will part with any of his articles.
The only way you can reach the corpse hole at Cadaver's Hollow is via Leyline Founts, which means you have no other option but to traverse the hostile overworld to make your way back to Gustave. Gustave not only sells things, he also buys relics of the human world and will give you a decent amount of Macca for them. You will also be rewarded handsomely if you find Minman, the little strange creatures that are Gustaves pawns and are scattered all over Da'at.
