The fantasy-action mini-series Twelve, led by Ma Dong-seok and Park Hyung-sik, debuted on August 23, 2025, across KBS 2TV and Disney+. Inspired by the Eastern zodiac theme, the plot follows twelve angels disguised as ordinary people, tasked with confronting the rising threats to the world. However, the initial episodes immediately drew mixed reactions, with viewers pointing out issues in storytelling and digital effects.The opening chapter focused heavily on explaining the lore and sketching characters.
