Geez, so many people in the Library.
That being said, Floodtalon, something to consider. It takes time for Melody to transform into a sandstorm. Arata and everyone else wouldn't exactly be doing nothing during that transformation sequence. Might be a good idea for you to edit your post so that it hasn't actually happened yet. And it might not happen at all, depending on what Rune's thoughts are about this whole thing.
Also, why does Chen think that Arata's an oni, just from a quick glance? Arata has blond hair and his horns are hidden by his cloak, so...nani sore?
