all characters

If you want your question to be filled, you should ask it in proper format. For example, your "question" is not even a question, it is a statement. Second of all, how is anyone supposed to know which character you do not have unless you tell us what characters you have unlocked. I am sorry for the inconvenience. I wish I could help you and I will try to to my full extent if you either edit your current question or submit a new, more proper and correct question.

You are missing yachiru kusajishi.If you don't know who she is, she is kenpachi's lieutenant. You can get her by completing arcade mode with uryuu a.k.a. Bow and arrow dude if you didn't know. Hope this helps and I am glad I can be of some assistance.
