The problem with Ashi was that her inclusion took time and focus away from things that people actually wanted, and pointed the show in a direction it should never have moved towards.
10 episodes to wrap up probably the most legendary western action show, something fans had waited over a decade for, and Genddy decides to dedicate more than half of them to his childhood waifu.

Sa-moo-rai gets a five second cameo.
