Pantera is a member of the Tomaso Famiglia. She apparently tries to kill Longchamp very frequently. Her weapon of choice is bladed pinwheels. Longchamp only thinks she's kidding around in her attempts to kill him, however, and dodges her attacks by instinct. When Tsuna asked Mangusta if something happened between them, he nervously refused to comment, implying that something indeed happened (though what happened exactly was never stated).
