Demon High School had already published 19 volumes. Was this novel finished? It was important to emphasize that this was a novel and not an anime.

As a fan of web novels, I didn't know about the latest developments in Demon High. However, generally speaking, comics are usually finished faster than novels, so it is recommended to keep an eye on the latest developments in comics.

The plot of the animated demon high school D×D novel had not yet ended. As of September 2021, the novel "Demon High School D×D" had been published in 12 volumes and was still being written. Although there was news that the novel would be completed in the near future, the specific completion time had not been confirmed yet.

I recommend to you,"Yes, Your Black-bellied Majesty." This novel was about a young school. It was about a girl who was recognized by a mysterious boy and was involved in a storm of illusions. The whole story was passionate and inspirational, full of mystery and the unknown. It was a good school magic novel. I hope you like this fairy's recommendation. Muah ~😗

The novel had already been published, but the internet hadn't finished updating it yet. There might be the following reasons: 1. The copyright of a novel is usually obtained by the publishing house at the time of publication, but when it is spread on the Internet, it needs to abide by the provisions of the copyright law and must obtain the authorization of the author or the copyright owner to publish the complete content. If the novel had been published but the copyright issue had not been resolved, the online updates might be affected. 2. The issue of update speed: When a novel is published, it is usually accompanied by an update schedule to ensure that readers can see the latest content in time. However, the speed of updates on the Internet platform may be affected by various factors such as authors, editors, and servers. Therefore, the update speed may be faster than on the publishing house's website, but it may take more time to update the complete book on the online platform. 3. Storyline problems: The plot of the novel may change after publication for various reasons, which may cause problems with online updates. For example, the author might make adjustments to the plot after publication or something else might happen to affect the development of the story. This could lead to problems with online updates, requiring authors or copyright owners to coordinate and update. 4. Other factors: During the process of publishing and updating the online platform, there may be other factors such as network server problems, reader feedback, etc. These factors could affect the speed and completeness of the novel.

There were many reasons why the novel had been published but not updated on the Internet. The following are some possible reasons: 1. The copyright of a novel is usually owned by the author or the author, but they have the right to edit and modify the novel for a certain period of time and then publish it on the Internet or other media platforms. If the novel had been published but the copyright issue had not been resolved, the network might not be able to continue updating the novel. 2. The partnership between the bookstore and the online platform: Some novels may establish a partnership with the bookstore and the online platform to publish the novel on their respective platforms. If the novel had already been published but there was a problem with the partnership with the online platform, the network might not be able to continue updating the novel. 3. The issue of update speed: The speed at which a novel updates may vary depending on the author, the publishing company, and the online platform. If the novel has been published but the author or the publishing company updates it slowly, the network may not be able to continue updating the novel unless the author or the publishing company updates it faster. 4. Market demand: The speed at which novels are updated also depends on market demand. If the novel did not gain widespread market demand after publication, the network might not be able to continue updating the novel unless the author or the bookstore could update it faster. There were many complicated issues between the publication of a novel and the update of the internet. Many factors needed to be considered.

The High School DxD light novel has indeed finished. It wrapped up after a long and exciting run, providing a satisfying conclusion to the story.

Sorry, I'm just a person who likes to read novels. I don't have real-time updates on novels. However, according to what I know, Demon High is still in the middle of a series.
