Shin Megami Tensei V Vengeance features several quests that require you to make multiple decisions. One of these quests can be found early in the game and has you side with one of two demons, Leanan Sidhe or Apsaras.
Choose between Apsaras and Leanan Sidhe
This guide will help you choose between the two in Shin Megami Tensei V Vengeance.
In order to choose between the two demons, you will first need to find them. The first demon you will likely encounter between the two is Apsaras, who is located in a cave in Shiba. You will know you are in the right place when you see her surrounded by many demons worshipping her. However, if you enter the cave before meeting Leanan Sidhe, you will be sent away by a Cait Sith demon.
You'll first need to find Leanan Sidhe, located near Tokyo Tower in Shiba Park. Once you meet her, she'll ask you to defeat Apsaras, who she believes is unfairly manipulating the demons below her, and this will trigger the Water Nymph quest. If you accept, you'll return to the cave and fight Apsaras.
