Kumo desu ga, Nani ka?

Synopsis

Nameless comes across a carriage being attacked by bandits and comes to their aid. However, after defeating the attackers, she notices one of the occupants, a vampire baby named Sophia, is a fellow reincarnation. Jealous of how easy she has it, Nameless departs but then notices a group of elves planning to kidnap the baby. So she disposes of them as well. In the present, Sue suddenly kills her father, the king, and frames Shun. Cylis and Hugo then arrest him and explain that the king was going to make Shun his successor to keep him off the battlefield, so they cooperated to launch this coup d'etat. However, Shun manages to escape with help from Ms. Oka and Hyrince, his maid Anna, and brother Leston. While recuperating, however, they are attacked by a group led by Hugo's reincarnation ally, who's revealed to be Sophia, and Katia, who has been brainwashed. While they are able to free Katia, Sophia and her assailants overwhelm them until Fei, who has evolved into a huge light dragon, arrives and they all escape on her back. Afterward, Sophia telepathically informs the Demon Lord that she completed her mission.
