Bleach 106 Discussion

[Yukimura]

I'd like to solve the plot puzzle, Pat. (THIS IS SPECULATION)

Yoruichi's little half-sister, (evidenced by her eyes, hair, and facial structure) current heir to the families crazy untold secret treasures comes to the real world to find her long lost big sister and otherwise wreak Shihouin-style havoc on everyone on earth. (evidenced by her apparent hyper bubbly personality). Then some dudes come from who knows where come to steal her secrets since she's the only one who both knows and can be beated up to tell them since they couldn't find our beloved Yoruichi.
