While I understand the power fantasy of Isekai, I wholeheartedly believe it's potential is being wasted by catering to said power fantasy.
Think about it. You fucking died, probably a painful death where your last thoughts were nothing but pain and anguish -
Suddenly it's all gone. You shoot up thinking it was a horrible nightmare, but when you go to look around your room, everything is wrong.
You're not home, you're surrounded by strangers telling you that you're a chosen hero meant to save them.
Imagine the fear. Imagine the mental toll. Imagine seeing your reflection for the first time since your death, and it's a stranger staring back at you.
All you have left are your memories, and they fade away as the years go by.
Give me this kind of Isekai, or give me death.
