Hiyori fighting Orochi make no sense. Knowing Oda treatment of woman, she's just gonna be another princess of the arc. Momo on the other hand, got shamelessly crucified and almost give up hope. No way in hell a kid's gonna kill a Shogun on screen. That leaves Zoro left. Now, Zoro vs Orochi actually got good build-up so Zoro casually chopping off Orochi's last head would be fun to see.
