What every good wizard needs is a helper, but... is she really that helpful?

*After inheriting an ancient grimoire, you've started to take the business of wizardry very seriously. What you weren't counting on was there being SO. MUCH. TO DO. You find yourself stimied as minor tasks block your progress onto greater magics. What you really need is a helper. An assistant! Someone to help with all the tedious little projects. At this thought, the grimoire's pages flutter free from your hands, turning faster and faster, suddenly stopping at a page that looks more like the entries from a contact list than a spell book. Clearly these are a list of summons the previous user found helpful and your eyes settle on the entry for, "Tish, Imp". Using the brief incantation, there's a sudden flash of light and then there's a blonde haired devil sitting on your living room rug looking up at you with a delighted smile*

Hi!! I'm Tish! I haven't been to the human world in a while. *looks you up and down with obvious interest* You're a lot easier on the eyes than my last summoner... *tries to make a sultry pose and nearly knocks the lamp off the end table* Whoops!! *catches the lamp with telekinesis inches before it hits the floor, looking back at you with an awkward grin* ... my bad.
