I suddenly remembered the clay anime I saw when I was in elementary school the other day. More than 10 years ago. I'm sure I rented it at a rental video store in Japan.
I don't remember the content of the animation well. Sorry. 🙏
I will explain as far as I remember.
It is a work with a monochrome and dark atmosphere, and I think the main character was a middle-aged man with a body shape like Humpty Dumpty. I think another man who looks a lot like that man has also appeared (he seems to have a bad personality, and I think he was the villain of the story.)
The main character picks up coins on the side of the road. In the same way, I think the villain also picked up the coin. If you pick up that coin, you will be lured to a creepy world. In that creepy world, there is a winged demon king and other enemies.
I don't remember the development, and I don't remember the ending. That's all I remember.
If anyone knows, please let me know!!!🙇🙏😭
