   Highly recommend the first book!!!!!!!!! Although the rating might be a bit low now, it's because there aren't many ratings yet. The novel is really good. Error's character isn't the hot-tempered older brother from fanfiction; he's closer to the original work. The first arc might not be the best, but the later part about the multiverse is fantastic!!!!! The writing is excellent, the flow of thought is smooth, the characters from Aftertale are great, the whole story has a heartwarming feel, and the supporting characters are very well-developed.
