Hey guys, I know that a lot of these theories have been posted already but here's mine. Sorry if it has already been suggested but here it goes. So, if we take the title apart, we know that the the "358" part most likely represents the number of days Roxas was in the organization. What I want to focus on in this part is the fact that it is about Roxas. Now, the "/2" part is left over. In fractions and what not, this means divided by 2. So, what I'm suggesting the title means is Roxas divided by 2= Sora and Ventus. It could also mean the splitting of two paths. This would mean that Roxas divided by 2 = organization and possibly another location or event. So, this is my theory. If you would like any more clarification, don't be afraid to PM me or just leave a response.
