Actual ending.
Erin: ...S-so I was SET UP FROM THE START!? BY THE GODDESS HERSELF!?
Mars: Yes, Erin, I had no choice but to make you suffer, it took time but I managed to...free you from that.
Erin: But...why would you do this? And...help me? Why? You would be in a prestigious position in all of this, Mars!
Mars: ...I fought aiming to save my people, when I noticed that this whole war was pointless, thanks to that Goddess? When I saw how that Priestess was actually? How those girls were really? Not about their lust, but their lack of morality?
*His face contorted in disgust and rage.*
From the moment I understood how far they would go for their pleasure, at the cost of men who were in a game rigged from the start with no choice...no way out...
They disgusted me.
Soon I saw them as pieces, not beings worthy of respect or dignity. Erin...we will fight together. Cast out that vile Goddess and act as we must. So Erin...
*He extends his hand, as Erin's eyes burn in sheer rage at everything laid out before him, the truth, undeniable.*
Let's join forces...and break those chains upon us!
