Hokuto no Ken Episode 79
Kenshiro thinks about Rei, another member of the Nanto Roku Seiken, who was the master of Nanto Suicho Ken (South Star Waterfowl Fist). He remembers how they fought together, and how Rei was given three days left to live by Raoh. Three days left to live...even in that time, Rei fought valiantly as the star of justice. And as Kenshiro knows, his struggle hadn't ended yet...
In the manga...
-This episode is filler and does not happen in the manga.
-There was a two week gap between this episode and the previous one during the original broadcast, usually new episodes aired once per week.
-When the narrator explains about Nanto Suicho Ken, part of Rei's collar flashes green a few times.
-During the preview for the next episode, Yuda speaks, saying how he is the most beautiful. But it is not his usual voice actor (Bin Shimada) saying this, and sounds like Shigeru Chiba to me. (Shigeru is the voice of the narrator, as well as several other minor characters like Joker and Komaku.)
