Psycho's Hideout is the third map in The Overlord's Daughter, disregarding the tutorial maps.
Psycho's Hideout has no cutscenes or dialogue associated with it.
You'll be challenging 1 Mothman and 4 Petite Orcs. There'll be a treasure chest near a house, but the only problem is that 2 Petite Orcs are near the treasure chest. There is a blue panel and a red Geo Symbol that is EXP50%, but the symbol is not on the panel.
The Dark World version of this map contains an Enemy Boost x3 panel completely covering the starting island (symbol on a single-tile panel on top of the house's chimney), and three high-level Mystic Beasts.
