@TwilightFaze Glad you enjoyed it, but it's too soon.
My prof likes to tell us, his students, to keep thinking radically. In his account, let's get fundamental. What is "Sekai (世界)"?
Yes. We're not using the word "World", as what we need to analyze is the concepts and the idea of what Japanese people have over the word "Sekai". After all, my challenge is to prove that this manga is not an "Isekai".
"Sekai" means everything that happens, evey phenomenon there is, that exists as a whole.
-> The Universe.
-> The Earth in its whole. Every human civilization on it. All the countries.
-> An assembly of a group of people. It's scope/vicinity.
Now we know the definition of "Sekai". Which means, "Isekai" is anything that is outside "Sekai". As the Kanji I (異) symbolizes "different, oddity, strange". Now, Japanese society is a racist one. That may sound harsh, but I gloss no sugar over my words. Tourists are considered an attraction by the Japanese when they stay being a tourist. But once you become a part of their society, you're treated like an outsider. Why? Because you're different. You're the 異 of them.
Well then, does the hell exists on our, using your word, "plane"? Do the Magic phenomenons happen in, well, our "realm"? I'm not sure I can find America in that hell, and vice versa, just in which part of the world is the Magic Academy Babylon rooted?
I see you've been mentioning about religions and cults. Don't take me wrong, I'm a religious man myself. Which allows me all the more to say that this manga doesn't make references to any religious ideas and/or ritual. Of course, it's impossible to claim that for an absolute. However, do know that this manga uses the term "魔界" which directly translates to "Demon World" instead of "地獄" which translates to Hell in religious meaning. There's also Limbo "辺獄" and Avici "阿鼻" in Japanese, a Buddhist idea of Hell (if I recall correctly). Despite that, the author uses the term "魔界" and not any other.
