Ragna Crimson

Ragna Crimson centers on a young warrior named Ragna who joins forces with a cold, mysterious swordsman called Crimson after dragons begin overrunning humanity. Their alliance is practical at first: Ragna wants to fight and protect, Crimson has the skills and uncanny knowledge to take down dragons. As they travel, their tactical fights and increasingly dangerous missions reveal how unevenly matched their motives and temperaments are, making trust a fragile commodity. The series keeps the focus on high-stakes combat and the duo’s evolving partnership, showing how cooperation, secrecy, and personal code affect the battles ahead without giving away any major turns or endings.

Released in 2023, the TV anime lists ヨシダタクミ, Deko Akao, and Daiki Kobayashi among its creators, and features Chiaki Kobayashi as Ragna, Ayumu Murase as Crimson, Inori Minase as Leonica, Mamiko Noto as Chimera, and Hiroki Touchi as Golem.

As of its initial run, Ragna Crimson hasn’t claimed major industry awards or high-profile nominations, though it’s helped raise visibility for several of its cast and creative team within genre circles and among anime viewers.

While not yet a mainstream phenomenon, the show made a mark with its visuals and character dynamics, prompting fan art and online discussion around the Ragna-Crimson relationship and standout battle set pieces. Its combination of dragon-slaying spectacle and a morally ambiguous ally gives fans clear hooks for cosplay and community debate.

Critics and viewers give it a mixed-to-positive reception, reflected in a 6.9/10 average from available votes, with praise for action staging and voice performances, tempered by remarks about pacing and plot economy. The series centers on themes of loyalty, the cost of violent defense, and how unclear motives shape teamwork, keeping the emotional stakes personal even amid large-scale conflict.
