Hit-Girl, apparently, is a hit. The first issue of the miniseries starring the supporting character from Mark Millar and John Romita Jr.'s Kick-Ass has sold out its first printing, which according to Millar was over 70,000 copies.

"Pre-orders for Hit-Girl #1 were over 70,000 copies, and we've completely sold out of first printing, the Noto variant and the limited edition white variant in 36 hrs.," Millar said on his MillarWorld site. "Marvel cleverly had an emergency second printing on stand-by and only 1700 copies of this left. So a third printing has not been ordered.

"... This is outselling even Kick-Ass and reaction has been amazing. Johnny and I very chuffed."

Millar followed that post up with another saying that the second printing was sold out. "Third printing on the way, people," he said.

Those numbers are especially impressive since Hit-Girl #1 was apparently left off of Diamond's initial retailer's order form.

The Hit-Girl miniseries takes place between Kick-Ass volumes 1 and 2 as the title character, a.k.a. Mindy McCready, tries to settle into life as a regular school-girl. According to the solicitation text, "Her mother and step-father think she’s doing her homework, but in reality she’s taken Kick-Ass on as her sidekick and training him up to punch, shoot and stab" ... and apparently sell a bunch of comics.
