Ratlua is a little too handsy and clingy. I wonder if he'd still do that if he knew Ivy was a girl. Sorry oniisan and oneesan, Ivy can not be your cute little brother.
So Ratlua and Mira are childhood friends...?
That makes me want to stop being suspicious of Mira for a bit, but Sora doesn't feel the same way. It doesn't help that her twin brothers have this literally shady look in their eyes when Ivy thinks of them. I hope it's just a red herring, but I really can't tell. In the extreme worst case, it's not only Verdant Wind that's suspicious but maybe even Ratlua too.
