Saigo's first part was a bit tough for me, initially. I didn't really know how to approach him. I had a stupid Hunting Rifle, while his was a sawed-off double barrel shotgun. He could easily get 2 hits on me while I reloaded my weapon. Then I realized, the closer I am to him, the more is the impact of his weapon on me. So I maintained some distance and kept moving side-ways and kept getting head shots on him. Before I know, the cut-scene rolled in. The rest of the part was dam easy. I find it funny Saigo mentioned about Dante and Beatrice.
