Hidden Ending

The hidden ending takes place during the beginning if Belial fails to make a pact with Shilo, Lior, and Renan. The route grants no CG BTW.

During each human love interests' Chapter 1, select the following:

Shilo Chapter 1 / pick the choice You're the same as every other human, just more vulnerable.

Lior Chapter 1 / pick the choice Because you looked like an easy target.

Renan Chapter 1 / pick the choice You're right. That was my plan.
