In Yukimura's fifth stage, The Osaka Campaign, you will begin in the castle. Defeat the officer that will come on your floor. Make your way outside the castle. You will see a lot of officers outside in the castle courtyard waiting for your bloodlust. Defeat them and the main gate will be open. The Tokugawa will send a cannon to destroy the castle and at the same time Inahime will approach from the east and Masamune will charge from the west heading towards the castle. Ignore them both and focus on destroying the cannon. Note: Do not worry if you accidentally kill enemy officers near the cannon. Once done, quickly defeat Ina before she enters the castle. Then, hastily cross the courtyard to the west, go through the castle, and defeat Masamune before he enters the castle. Note: You are free to kill the officers near Masamune. You will then get the precious item report and the weapon will on the second floor, in a black box. After that, you can finish the stage normally. Note: You may want to seal the gates to make your ally officers easier and try to use your second attack. The weapons stats are Base Attack 45, Fire Element, Life +19, Attack +35, Defense +38, Horse +18, Musou Charge +32.
