A reclusive gamer just minding his own business at an e-sports tournament, Chen Kefan watches his world shatter — giant bug monsters tear through the city and the person who murdered his parents shows up again. Great timing. Turns out the peaceful city everyone lives in has been secretly protected by a barrier maintained by the Sword Bureau, whose elite Fortune Star agents have been fighting calamity creatures for decades. When those agents get kidnapped, the whole defense system crumbles and the city gets overrun. In the chaos, Kefan's dormant Fortune Star powers awaken, dragging him straight into a war he never asked for — but one that's deeply personal. The setup hits that sweet spot where personal revenge and larger apocalyptic stakes collide from the jump. Original Force animated this ONA, and the action sequences blend futuristic and traditional combat in a way that feels fluid and stylish. The power system around Fortune Star abilities has real depth to it, and the soundtrack does a lot of heavy lifting to sell the urban fantasy atmosphere. There's also a running thread about fate versus free will that gives the story more weight than a typical action show. If you're into donghua like Under One Person or Quan Zhi Ming, this scratches a similar itch — modern urban setting, secret supernatural world, a protagonist thrown into the deep end. It's action-packed without being mindless, and the mystery around the Sword Bureau and the calamity creatures keeps things interesting beyond just the fights.
