Kingdom anime is just one of the media with which the story is presented. The manga is ongoing, 762 chapters and counting. The live action film is on its third installment but available only in Japanese theaters. It's a franchise that will not likely reach Kimetsu No Yaiba or Attack on Titan levels internationally with the stark absence of English translations, but for a huge fan like me, it is worth crossing the language barrier for.
Chinese war drama in the hands of mangaka Yasuhisa Hara. This is what it is. Many of Hara's characters jump straight out of history, and they transform into larger-than-life generals, kings, vassals, and scholars, warriors, courtiers, in often flamboyant costumes and hairpieces. The two main leads, orphan warrior Shin and 31st King of Qin Ei Sei, carry the heart of the series (these two are the least flamboyantly dressed tough), and through their stories, together or apart, they share the goal of unifying the warring states and ending war for good.
There is some criticism about the inconsistency and cartoonish aspects of the anime, but that can be overlooked as the story unfolds. Overall, Kingdom is epic storytelling, and I can see many more chapters, seasons, and movie sequels on the horizon.
