A vampire chooses extinction over silence, knowing the cost is eternal punishment. This show trades movement for weight, spending five minutes per episode on ideas most anime spend five seasons avoiding. The visual language is so specific, red dust for vampire death, the moment before zombification for human dying, that every frame feels like it's saying something you can't unsee.
Humanity stands on the brink of extinction. People have lost their purana, the vital essence every living thing needs, stolen by a mysterious virus. Vampires have long kept the cure to themselves, and the world has slid into chaos. A vampire named Duo breaks that taboo and reveals the secret of purana to save the human race, and his own kind now brands him a traitor. The one sent after him is Zieg, a powerful vampire who was once his close friend. Zieg's sense of duty tells him to kill the man who betrayed their people, but their shared past pulls him the other way. The result is a short supernatural drama about friendship, loyalty and the price of betrayal.
