Right. Of course you wouldn't. [There was the faintest hint of longing in Hisoka's tone then; the library in hell was one of the greater pains. Books beyond limit, and yet daring to open one himself would result in impossible suffering.

He didn't even yelp when the leash was tugged and nipped him into motion. He simply followed as he was led.]

Yes, Master. [He announced it in the innocent pitch he used in front of an audience, just in case an ear was close to the door they approached.] You're really smart to read all those books. They don't even have pictures! I'm a very lucky pet to have such a smart Master.
