Fourth Weapon Acquisition

 * Requirements: Defeat the officers in the following order: Toshiie Maeda/Generics, Nobunaga Oda, Nō, Ginchiyo Tachibana/Ina, Ranmaru, Okuni, Nene, and Nō once more.

Strategy
Begin by defeating some nearby enemy generals. Okuni will show up to assist you, and Nene will show up on Nouhime's side. Eventually Nagamasa will try and charge out of his home base to assist you, but he'll be ambushed. Go up and defend him by defeating his ambushers. Now go all the way to the south and defeat Nobunaga. Return and defeat Nouhime (beware, Nene will be in your way, and you can't defeat her yet). After you do so, Tachibana Ginchiyo and Inahime show up. Defeat them both. Okuni will also turn hostile around this time, but again, you cannot defeat her yet. Mori Ranmaru shows up as well; defeat him. Finally, you can now defeat Okuni and Nene, in that order. Nouhime will show up a second time, and the supply team will show up as well, from a gate on the left side of the center area. Pick it up and defeat Nouhime to finish. This weapon can be quite tough to get thanks to the sheer number of unique generals mobbing you and Oichi's only so-so crowd control.
