Where can I stream the anime Origin Spirits Of The Past?

I've looked everywhere, on all legal and illegal anime streaming sites I know and also on Netflix and Amazom prime.

But nowhere do I find the anime. I would see it, does anyone know where I can see it?

"Origin: Spirits of the past"

Although it is licensed, it is currently only available via https://www.amazon.de/...B00TVNYUPS
