Ep 1. The World of Blood Legacy

The World of Blood Legacy, the first episode of the Seraph of the End: Vampire Reign series, introduces viewers to a world that has been ravaged by a catastrophic virus. This virus has wiped out most of humanity, leaving only the children under the age of thirteen alive. To make matters worse, vampires have emerged from the shadows and have taken control of what remains of the world. The only hope for humanity is a supernatural army called the Moon Demon Company, which is made up of children who have been willingly turned into powerful weapons to be used against vampires.

The episode opens with a group of children who are being held captive by vampires in a subterranean hideout. One of the children, a young boy named Yuichiro, has been plotting a daring escape with his best friend, Mikaela. When the opportunity arises, the two boys make a break for it, but Mikaela sacrifices himself to allow Yuichiro to escape. Yuichiro's escape takes him to the surface, where he is quickly found by members of the Japanese Imperial Demon Army. The army is made up of highly trained soldiers who are all too aware of the danger that vampires pose to humanity.

Yuichiro is brought to a military outpost where he is given an opportunity to join the Moon Demon Company. He eagerly accepts, as he sees it as his only chance to get revenge on the vampires who killed his friends and family. However, he soon discovers that becoming a weapon is not as easy as he thought. The process of becoming a demon weapon involves binding a demon to a human host, which is incredibly painful and potentially fatal. Yuichiro and the other children in the Moon Demon Company are put through a grueling training regimen to prepare them for the transformation process.

Despite the challenges he faces, Yuichiro is determined to become a demon weapon and take on the vampires. He forms close bonds with his fellow trainees, including a girl named Shinoa who becomes his mentor. Shinoa is a skilled fighter who takes a liking to Yuichiro and helps him through the difficult training process.

The first episode of Seraph of the End: Vampire Reign sets up a dystopian world that is rife with danger and uncertainty. The concept of children being turned into weapons is a chilling one, and the show doesn't shy away from the violence and brutality of this process. The episode also sets up the main conflict of the series, which is the battle between the Moon Demon Company and the vampires. The tension between these two factions is palpable, and viewers are left wondering what the ultimate outcome will be.

Overall, The World of Blood Legacy is a strong start to the Seraph of the End: Vampire Reign series. It introduces viewers to the main characters and the world they inhabit in a compelling way, while also setting up the central conflict that will drive the story forward. Fans of dystopian anime and dark fantasy will find much to appreciate in this first episode, and will likely be eager to see where the story goes from here.
