Just realised somethin major

Every single MC that comes to "another world" is an "alien" technically. And to them everybody else is. We don't realise this commonly because everyone else is portrayed as human and in some anime they even call themselves human, which is weird but I guess it works because it's fictional media. The different races in some anime such as beast people, elves, dwarves etc literally show you that they're not human but we gloss over the fact that the MC who's an alien talking to normal people 🤯. I was just watching beheneko & thinking that, how the cat with human soul is so totally not a "cat" yet gets treated as one then thought about every single protagonist/antagonist is the same.... they're an 👽 alien 👽 treated as humans.🤯🤯🤯🤯🤯🤯
