^Manga^ If starting with xxxHolic Volume 1 at which point would it begin to crossover with Tsubasa (and which volume) This is not something that is really explained or easy for someone to find. A crossover timeline needs to be created for those wanting to not be confused. I picked up xxxHolic V1 today and was really curious as to when I need to start with Tsubasa. I didn't plan on posting about it but while searching for answers I found a lot of other mass confusion on anime forums and websites. If you have figured it out, it would be valuable information to myself and many others. Or a link to such information would be just as valuable. Either way, i'll make sure it becomes public info because of the immediate need. Excited to get into it once I find out.
