@Tanatat: Yup. And sadly, there's a large chance they aren't brothers since we would have seen more interaction or they may be related BUT have different parents or one of them is adopted. Either way, I want the 'Ibuki and Hakuryuu' brothers theory to be true lol (but that's just my fangirl side talking). Looking at the anime though, it doesn't seem like they're brothers ;_;
