Swallowed Star 4th Season

After the RR virus mutated Earth's animals into city-leveling monsters, humanity was left clinging to survival inside fortified base cities. Luo Feng started as a kid trying to make it as a warrior in this meat grinder of a world, and by this fourth season, he's become one of humanity's heaviest hitters — but the threats have scaled up to match. The season kicks off with a golden-horned behemoth tearing through the American base city, and it's the kind of problem that makes everything Luo Feng has faced before look manageable. With his AI companion Babata and a crew of elite fighters, he's got to figure out how to deal with extinction-level creatures while the power system keeps getting deeper and weirder, blending martial arts cultivation with sci-fi tech in ways that actually feel thought through. Sparkly Key Animation Studio's 3D work here is genuinely solid — the fight choreography hits hard and the scale of the battles comes through. At 175 episodes, this ONA has room to breathe without dragging. If you liked the cultivation grind of Douluo Dalu or the power scaling in Stellar Transformations, this scratches a similar itch but with a post-apocalyptic sci-fi wrapper instead of pure fantasy. Fans of Martial Universe will also feel at home with the tone. It's a world where getting stronger isn't vanity — it's the only thing keeping the species alive.
