What have you done to my Diabolical System?!

"What's the cost of it?", asked Harry, slightly startled.

[Nah, I couldn't charge such a good and benevolent Host. It's free!]

Harry stared blankly. He then screamed, "Who are you?! What have you done to my diabolical system?!"

If the system had a face, it would definitely have a dark expression right now. It said angrily,

[Is it so bad to try to be nice?!]

Harry blinked a few times and said, "Well, it is if it's a system that's trying to be nice!"

[Host, do you want the temporary powerup or not?]

Harry was about to respond when the mocking voice of the witch rang out again.

"What happened? Do you think we will let you in if you stand there like a statue? Maybe I should kill you personally? Oho! Maybe you are frozen in that spot because of fear! Makes sense. After all, you humans are fearful morons, and you must be scared after realizing that you won't live."
