'What could I have done then to cause this phenomenon?'
After a while, Rain came to the conclusion that he might not have been the cause of it.
'Is it possible that back then, in the rift, the Goddess of Darkness was watching my battle and she was the cause of that dark aura?'
Considering that it ended up changing the story and getting the attention of the World's Will, this could very well be true.
[Since we were separated, I don't know what she's been doing. But I don't think the Goddess would watch over your life, knowing that it's 90% of yours... games.]
'I wouldn't hold back and peek at it at least once if I were her.'
About that dark aura, Rain supposed that one of them might have been lying, but after thinking about it he came to the conclusion that it didn't make sense for Sives to do it, and the system... he wasn't sure about that, but at the moment he decided to take her word for it.
