Kosuke-sama Rikimaru-sama: Konpeitou no Ryuu

It has same character design and it is a martial arts adventure story too. 

Kosuke-sama features similar character design unsurprisingly as they're both done by Toriyama. Fans of Tori's unique style will enjoy this short movie which is very reminiscent of early dragon ball with similar characters to Goku, Kennosuke, General Black & Icarus. Both are movies with distinct charm and likeable characters.

These are both early work of Akira Toriyama, Ackman is based of a one shot of his and Kosuke features his iconic character design. Fans of Tori's unique style looking for more content by this classic creator will find enjoyment of both of these anime.
