Unlike the main storyline, the Overlord Prier episode contains 4 different endings. (: 1 bad, 2 standards, and): 1 good. The ending you get at episode #4 depends on how many episodes you've gotten norma/good.
 
 

Ending conditions in Overlord Purier Route

These are the ending conditions for each episode.
 
 
To trigger a happy ending in episode 1, talk directly to the orphanage child and search for the (glows red) event point on the dungeon’s second level.
 
After the good ending of episode 1, you can search for the event point on Episode 2.
 
After getting a great ending on episode 2, search episode 3 for the event point on the fourth level of the dungeon.
 
For episode 4, search the event location on the first fight following a satisfying ending to episode 3. (Inside the Church vs. Four Demons). Do not fight vs. enemies before triggering this event point.
 
If you ignore the point, you'll get a normal ending. If you ignore the event points, they will not appear again in later episodes.
 
 
Here are the conditions to each episode's ending:
 
 
Bad end – At episode 4, don't trigger the event points and get your party wiped off at the second Battle (Inside the church: Father Salade).
 
Normal end 1- Get standard ends at episodes 1,2 and 3. Clear the game.
 
Normal end 2- Get a better ending in episodes 2, 2 and 3. Clear the game by disregarding the event point in episode 4.
 
Good end – Check episode 4 for an event point and complete the game.
