Vs. the Armstrong Cannon is the one hundred eighty-fifth chapter of the Rurouni Kenshin manga.
Synopsis[]
Kenshin strikes Kujiranami with the Kuzu Ryu Sen in midair, putting the whalemouth to the ground.
Once Kenshin makes his landing upon the roof of the Kamiya Dojo's front gate's roof, he releases the built up ki inside of him. Kaoru looks in shock at the rurouni, wondering if he is changing into Battousai. But Sanosuke reassures to everyone who did not see Kenshin's battle with Shishio that the current Kenshin has surpassed the skill of Battousai.
Kujiranami slowly gets to his feet, preparing to fire at Kenshin again. The others run into the dojo fo shelter, but Sanosuke pulls up something from underneath the porch. Removing the cloth from the item, Sanosuke reveals his old friend, the Zanbatou, held together by two large metal staples. Kujiranami fires his Armstrong cannon, but Sanosuke clobbers the cannonball back, breaking his giant sword in the process. Kujiranami swats the cannonball away from him, causing an explosion behind him. Before he is able to reload, Kenshin cuts the Armstrong cannon from Kujiranami's arm, and hits him on the side, underneath his arm which brough immense pain to the one-armed man.
Though the first battle has been won with ease, the fight has just begun and Enishi will not come down until all of his comrades have fallen. To make things interesting, both Inui and Otowa leap down from their hot-air balloon and take to the field.
