Sword Demon Battle Ballad: Curtain's Close

Sword Demon Battle Ballad: Curtain's Close (剣鬼戦歌――終幕) is a side story featured in Monthly Comic Alive. It is the ninth of nine total acts in Sword Demon Battle Ballad and a sequel to Re:Zero Ex Light Novel Volume 3.

Summary
After the defeat of Stride and Valgren, several events took place. A state funeral took place for all the victims of Stride's machinations including Roswaal J Mathers. Many attended it, including her son, now already possessed by the original Roswaal. Wilhelm swore to become Karl's strength during the funeral, and Carol who was overwhelmed by regret was given comforting words by Karl.

At some point later, Kurgan was returned back to Vollachia as a political maneuver to put Vollachia in debt to Lugunica and force them to admit Stride's involvement. Kurgan mentioned during his transfer that he was surprised that Stride had called a true dragon, and not an evil one, and that it bent reason. He commented that by this Stride had fulfilled his most cherished desire. Valga Cromwell was also visited by Miklotov after he'd begrudgingly helped the Kingdom with information during their battle against Stride. In addition to that, Razak Gildark assisted with protecting the citizens of Picoutatte after they were turned into the insurgent mob, and that he'd saved the life of a young Rickert Hoffman at the cost of his own.

Following that, various promotions were given to both Wilhelm, who became one of the members of the Royal Guard, eventually becoming its commander, and to Grimm who received a rank tantamount to aristocracy. This allowed Grimm to marry Carol, with the former leaving the Zellgef Corps and serving the Astrea family.

Finally, Wilhelm handed Theresia a letter that Tishua had given him from the deceased Veltol. The letter contained a list of names he wanted to call their unborn child, with only one circled. That name was Heinkel; that led to the couple naming their child Heinkel Astrea.
