The most exciting new character of the year debuts as Hit-Girl slashes her way into the pages of Kick-Ass. She's nine years old, loves Hello Kitty and could rip out your windpipe before you even get a chance to plead for mercy. But where did she come from? And who is Big Daddy? Plus, Kick-Ass starts to find out what happens when you tick off the real-world criminals who have ignored him until now. Things turn ugly and that can mean only one thing...God, this comic is so good I could cry. And I'm very butch.
The issue begins where the last left off, Hit-girl brutally murdering everyone in the room that Dave had visited to convince Denny Lomas to leave his ex girlfriend alone. Everyone in the room except Dave and Hit-girl is soon left dead by Hit-girls katanas. Hit-girl then leaves the room jumps across a building and meets up with her partner "Big Daddy", Dave describes them to be the "real deal"
Dave lives the next few days in total guilt of the murders and fear that they may be traced to him, but relief comes quick when the killings are blamed on someone else.
Dave also find that he started a sub-culture of superhero wannabes and that ripples from the murders are going around the criminal underworld causing Dave to promise himself that he will hang up the mask a second time.
