User blog comment:Mr Easter/Could Kuina be tashigi/@comment-972068-20131215000131

I think if Kuina was Tashigi, or if there's some connection, it would be addressed by now. Remember, the last time Kuina was even mentioned was Tashigi's introduction. This was over 600 chapters ago. Tashigi has had quite a few appearances since, and not a single one of them regarded Kuina or Zoro. If there is a connection, it's a long-lost twin. That's basically it.
