CATDOLL: Is it plagiarism or laziness? The theme song of the third season of "Sailor Moon Crystal" is very similar to "Higurashi When They Cry"

As soon as the third season of the popular Sailor Moon Crystal animation began airing, some netizens with good eyesight noticed that the storyboarding method of the animation theme song was exactly the same as that of Higurashi When They Cry. So what is going on? Let's take a look.

From the picture, we can see that the theme song storyboards for Crystal Season 3 are basically the same as those for Higurashi No Naku Koro ni. Even the actions and scenes are similar. However, the funny thing is that the theme song storyboards for both works were all produced by Kon Chiaki alone. To put it bluntly, they were all made by one person. So, can this be considered as plagiarizing oneself? Or maybe the producer was just being lazy.
