Japanese pop-metal group Babymetal have been met with their fair share of derision, but their popularity seems to only be growing. Now, a new digital hybrid live-action/animated action-adventure series is in production based around the band’s adventures “inside the magical world of heavy metal music as it comes under attack,” according to Deadline. The series will feature brand-new live-action performances from Babymetal opposite an animated storyline, which the members will enter “through a secret portal.” The series is being produced by Warner Bros’ digital outlet Blue Ribbon Content and Japan’s Amuse Inc. subsidiary Amuse USA, alongside Babymetal manager Key Kobayashi. The series is being aimed at US audiences.
