I watched with my wife. Here in Brazil, there was something called "Animax", which was like a channel dedicated to anime, which is very nostalgic for us, and there was a section of the day called "lollipop" that would have some anime that were promoted as ecchi or something like that, we decided to watch SpeedGrapher just for nostalgia and giggles, but the anime barely had anything erotic, we were surprised to see a good story about capitalism, war and money, something that really sticked to me was the main antagonist and his story with his sister, I remember him saying something like "All of this... just for money". The powers were interesting too.
