I'm absolutely appalled at them making Rin Towa and Setsuna's mother, what kind of message are you showing to children on the same age demographic? It's disgusting to make them feel comfortable at child grooming and pedophilia and, so far, the plot isn't even that cohesive. There are fanfic creators that could right an even better sequel with great worldbuilding and plot and, even better, no child grooming and pedophilia as the eye can see.
