Love the plotline and the art! Highly recommended because this story actually made me choke up at the more emotional scenes. not and lot of stories do that for me! My theory ahead
THEORY: The sorcerer is the demon king because if u think art it the story lines up. With helen seeing the footprints go toward the beach that means that sibyl actually came from the demon island not just to visit it. And that happened abt a couple weeks prior to the unicorn being backstabbed. Which means that when sibyl left after attacking sky island he went down to the nether and morphed to a human. And so on through the plot. Also maybe the reason why sibyl cant touch desire is cause he is hostile. (Im not sure at the desire part)
