Maybe there was a smile cult which inspired so many stories to be made out of.
My 5 minutes research says there wasn't one
I think these are compilations of all the cult or murders that took place around the world, I mean again, I'm just guessing here. Idk!!
Or maybe it's just a story unrelated to anything but I really like this plot!!!.
Now I'm gonna read Mob Psycho now that you've mentioned it
Nope. Cults like that are more common than you thought. I immediately thought of Japanese cult's Happy Science when reading this manga for the first time.
That's a good read but better anime experience
Okey that's interesting I will check that out, and I said 5 minutes of googling just in case if anyone would think that I'm knowing anything abut the subject
Isn't the idea of the smile cult inspired from Mob Psycho?
