Heads Up (決闘) is the ninth episode of the Darwin's Game anime.
- Danjou's backstory is cut.
- Kaede reveals that the woman who interrupted the fight was Xuelan.
- The anime skips the scene from the restaurant. Because of this, Xuelan doesn't kidnap Inukai, therefore any scenes involving him after the match are cut.
- Part of the Sunset Ravens' meeting is cut.
- Kaname and Xuelan's dialogue is extended, partly because Inukai isn't kidnapped.
- Wang's video is given dialogue instead of just one panel in the manga.
