Won't stop Moving Forward

'A man? A woman?'

Their voices mixes and confused Troy.

Troy had known about the Corrupted Saint for long. But he never actually meet face to face or speak to them. 

In the past, even the other Saint did not know about the original of the Corrupted Saint. They just said the Corrupted Saint always be in the rearward, healing and confronting the wounded. 

Now there he is, flying with their Corrupted Angel child, above a giant black hole leads to the Lower Floor.

"Say, Fated One, why did you do all this?"

Ars confused at first. What context makes the Corrupted Saint asked that? Then he realizes he steps on someone's cinder. 

"He destroyed my castle and killed my child."

Destroyed his castle is reasonable, because they were at war. But Ars' future child? 

'Aren't his children yet born? Does that mean - ?'

Cinderella killed them inside theirs' mother belly. 

So therein lies the source of Ars' wrath.
