Rukia & Mizuiro Hair

Do any of you guys remember when Rukia first enrolled in Karakura High School? You know, where readers are first introduced to Ichigo's school friends. Well, what always got me in that first school moment in the series was that Mizuiro and Rukia have the same hair style. When I first saw the two of them together in a panel, I had to take a second glance. It seems as though Tite Kubo has given both characters the big, round hair with outwards points at the bottom and the loose hair hanging across their foreheads. I wonder why? If any of you have read and/or seen Inuyasha (http://en.wikipedia.org/wiki/InuYasha) some of you may have realized the similarities between young Rin and Kagome. My conclusion, in comparison to both accounts of similarly designed character appearance, is that Mizuiro, though not mention so far, is one of Rukia's ancestors. Think about it. Rukia states that she has lived "many of your lifetimes" to Ichigo when they first meet in his bedroom. This opens the possibility that her family line could have continued for a few generations after she died and became a Shinigami thus resulting in Mizuiro later being born and growing up as the main character Ichigo's best friend. Comments on my theory?...
