Professor Gregory was in danger

Outside the Forest of Truth, the setting sun cast a bloody hue across the sky.

Mike withdrew his gaze, puzzled, and asked, "Seven Bro, why would they bring Professor Gregory to negotiate with the demon gods if it's so dangerous?"

"I find it strange too," Shadow Seven's voice came from above Mike. He glanced up, startled. Shadow Seven was standing on a 'small mountain,' crouching to talk to Mike. This mountain was entirely made of demon creature corpses. Unbeknownst to him, she had killed so many demon creatures.

"Seven Bro, isn't it cold up there?" Mike asked, "Do you want me to burn the bodies for you?"

"Burn? Why burn them?" Shadow Seven was puzzled. She was used to killing but not burying. Slashing was all that mattered.

Mike explained seriously, "Burning the bodies erases the traces of your actions, making it impossible for the enemy to deduce your usual methods from the corpses."
