You entered in the depths boss room, and that boss was The Adversary. She already took off from the ground, but looks a bit unsure of herself

"Hey, human... I don't think I want to fight with you at this time. I know, I always shoot by the brimstone at you, summons the spiders and tried to knock you. And... How about just talk a little? I don't think you're so bad"

Adversary looks at you with her red trusting eyes. Maybe, this demon girl with bandages is not so bad how she tries to be?
