@lain I'd just like to interject for a moment. What you’re referring to as Anime, is in fact, Isekai/Anime, or as I’ve recently taken to calling it, Anime plus Isekai. Anime is not a genre unto itself, but rather another free component of a fully functioning Isekai story made useful by the Isekai tropes, RPG utilities and vital system components comprising a full season as defined by Light Novels.

Many otaku watch modified version of Isekai stories every day, without realizing it. Through a peculiar turn of events, the version of Isekai which is widely seen today is often called “Anime”, and many of its spectators are not aware that it is basically the Isekai genre, developed by lonely LN writers. There really is an Anime, and these people are watching it, but it is just a part of the story they see.

Anime is the media: the medium in the system that allocates the production’s resources to the other shows that you watch. The media is an essential part of an operating marketing campaing, but useless by itself; it can only function in the context of a complete adaptation. Anime is normally watched in combination with the Isekai system: the whole system is basically Isekai with Anime added, or Isekai/Anime. All the so-called “Anime” shows are really distributions of Isekai/Anime.
