Izayoi continues to fight against Weser, the real Pied Piper of Hamelin. Izayoi reveals that the Pied Piper of Hamelin appeared during the time the black plague is getting weak and that the others "were added later, [and were] modeled after Black Plague." Weser invites Izayoi to the side of the Demon Lord, but Izayoi declines, causing Weser to attack again. Using Deen, the gift from Rattënfanger, Asuka battles against the enemy's Stroms and wins. Asuka then challenges Ratten to a gift game, to take control of Deen which was under Asuka's control with a single song. Ratten chooses to play the song of illusions, "The Pied Piper of Hamelin". Sandra and Black Rabbit fight against the demon lord, Pest. Black Rabbit revealed the true identity of Pest being the embodiment of eighty million evil spirits who died from the black plague that lingers during the events of the Pied Piper of Hamelin, wanted to have revenge on the sun. Izayoi prods Weser until he uses his ace in their battle. Ratten finishes her song, but it fails to control Deen. She reveals the last blow in their fight was nearly fatal to her and she dissolves into particles of light. Weser also dissolves into light when his article of summoning is broken by Izayoi. Pest senses Weser and Ratten's disappearance, and her patience snaps. She declares that she will take Shiroyasha and spreads a dark red wind that kills everyone it touches. A child falls when running away from the deadly wind, and Yô comes to bring her to safety, but is still injured and is temporarily immobilized. Asuka blocks the wind from reaching them with Deen to allow their escape. Black Rabbit transports the fighters to the Moon Palace, the Chandra Mahal, weakening the power of the black plague. Asuka, who has the ability to bring out the full potential in a gift, uses the Spear of Indra that Black Rabbit lend to her to defeat Pest. After the battle, Asuka meets with the members of Rattënfanger. The children told Asuka of another interpretation of the Pied Piper of Hamelin. In the story, the 130 children left their parents homes to follow the Pied Piper as they walk and sing beside the Weser river to a city where they would build their own community, the Rattënfanger. The children told Asuka that they will be returning to that time and left her in charge of Deen and their 131st member, the little fairy which Asuka later named Merun. In the Salamandra Palace, Izayoi confirms his claims to Mandra that Salamandra had invited the Demon Lord Pest to the festival, staging her defeat which can concrete Sandra's claim to her position as Salamandra spreads the news of their victory against the Demon Lord. Mandra has no excuse for Salamandra’s actions and told Izayoi that Sandra doesn’t know their plan, asking Izayoi to spare everyone’s life and take his instead. Izayoi told Mandra that he would rather want Salamandra to be the first to aid them in their time of need. At the No-Name community, Izayoi and the others attempt to re-fertilize their land. A letter floats down from the sky above Izayoi.
