Hammer Girl is a mass murderer, arsonist, vigilante and former assassin for hire who worked for Bejo before his death at the hands of Uco who then proceeded to die at the hands of Rama. She was resurrected, along with her brother Baseball Bat Man, after her death in the fight against Rama. Now, she and her brother are vigilantes and seek to target other "big fish" in this great spider web that is the criminal world. Despite being hardened murderers, they apologized to Rama, who accepted their apologies in advance, and formed bonds of alliance "in case the maelstrom happens in this sea again." Along with Rama and Prakoso, Bat Man and Hammer Girl prioritize the necessary focus of ending "the rats, vermin and parasites that try to ruin the beauty of Indonesia, but will not succeed." They are applauded by locals, who call them better than the authorities.
