Impmon (NPC)

Once you help him open the Arcade, Impmon will allow us to go to the Dungeons. Dangerous places crafted from previously gatherer data that allow us to get plenty of resources.

Quest

The gran Opening!

We will first meet Impmon on the right of the Fame Hall, on a construction slot in File City.

He will ask for your help gathering enough materials to finish the building:

Once completed, the building will be ready for the opening!

First Dungeon: Deep Caves

Once the Arcade is open, Impmon will ask for some Dungeon Data. It will be needed, otherwise exploring dungeons would be difficult.

So you must look around for something that might qualify. Im sure that you could find someplace dark and deep enough to explore now that you know what you should be looking for.

Once you have enough Deep Cave data, come back and Impmon will be able to open that dungeon anytime you want!
