Helldriver

In a post-apocalyptic Japan, Kika, played by Yumiko Hara, embarks on a perilous journey across a dystopian landscape in search of her mother, the Zombie Queen, Rikka, played by Eihi Shiina. After a meteorite impales Rikka, her heart is transplanted into Kika's chest, granting her an artificial heart and a chainsword that allows her to kill zombies by severing their horns on the top of their foreheads. As Kika navigates this treacherous world, she must confront her mother, who has become a monstrous force controlling a giant body made of zombies, leading to a violent showdown between them.
