Kozure Ookami Chapter 127 Discussion

                        ----------------------------------------

                        Itto is training Diagoro by making him hit him with a large stick. He's been practicing tirelessly to improve his skill and get use to the weight of the stick. Now he's able to hold and swing a katana from Itto's training. Plus he learned how to hit a human body, so he's use to that now as well.

Diagoro is going to stay behind and protect Itto and Retsudō's swords while Itto attempts to save Retsudō so they can finish their duel.

Ittou plans on entering the Edo Castle. How will he do it though?
