Ok, we understood that Arturo was a villain beyond redemption, but one thing that made me question is that he killed all kids in the Human Village, so it means that he killed an entire generation of humans? I know the humans will repopulate, but it's still complicated, or was it a case of Broad Strokes?
Word of God here: It's Broad Strokes. Really, would you trust a poorly-made video by Yukari? The nature of Arturo's story will be revealed later. You can find the truth behind Arturo and Yuuka hidden somewhere on one of the Diamond In The Rough pages.
