Then you have to read the serialization of comics. The current serialization of comics is too slow. It is only the second round of the national competition. It is not possible in one or two years. It is conservatively estimated that it will be at least three years, but there are rumors - Achi Congratulations, the new episode will be aired in April this year. You can take a look. The side story has a certain connection with this episode. Some characters in this episode will also appear in the side story. The time period is the same as this episode. The progress is very likely. It has reached the national competition (the comic has already reached the end of the second round of the national competition), and it is quite interesting to look at the story from another perspective.
(PS: By the way, I want to complain about Saki's "Big Demon King" image in the side story, which is too domineering!!!)
