(Source: Crunchyroll) Note: Short stories adapting Hokuto no Ken: Ichigo Aji manga are included at the end of each episode. Serving as a spinoff gag manga of the original Hokuto no Ken series, the story is a parody of Fist of the North Star by Buronson and Tetsuo Hara. It consists of page-long gags centered mainly on Souther, both within his final battle with Kenshiro and inserting himself into other parts of the series where he doesn't belong. One recurring gag involves the kid with a turban repeatedly stabbing Souther in the leg every time he climbs the pyramid's staircase, and another involves Rei suddenly transforming into Souther in his iconic moments.
