Tiffany

The little girl was the person Alex desperately searched for several days. 

She swiftly ran out from the trees. Looking at her pale contenance, Alex thought she probably had been hiding there for a while, observing everything that had been transpired.

From the woods across the river, Tiffany once again shouted, as she was afraid that Cerri didn't hear her, "Stop Stop! Please don't hurt my dad!" She said, while moving next to Cerri and grabbed the hem of the mysterious girl's clothes.

To Alex and the others' complete surprise, his daughter was able to make the legendary beast stop its charge, even when Cerri didn't give the order yet.

Seeing that his gamble was working, Heinrich appeared to be extremely glad, "Hahaha, I knew it! The little girl is the key."

Heinrich's ambiguous words made Alex extremely irritated. After all, it was his daughter that he was talking about!
