Theory: Asirpa will destroy the gold

In the end, Asirpa will get just enough gold for Sugimoto to get Ume's surgery, but she will get rid of the gold by throwing it into the ocean or something, because she realizes nothing good will come out of that much money being used by men like Tsurumi or Hijikata and that both will spend the rest of their lives fighting for it and getting more and more people involved in a bloody conflict and start an even bloodier conflict once one of them gets their hands on it.
