The PC-Engine port of the Game Boy game under the name of Momotaro Densetsu Gaiden. A spin-off of Hudson's Peach Boy RPG series that focuses on three side characters instead.

The game switches focus from Momotarou to three extra characters, each has their own distinct campaign to play through. One follows a standard RPG route of a hero's journey, another involves the princess of the kingdom of demons as she attempts to uncover an attack on her father's throne with a band of allied monsters, and the third involves a thief who steals money from monsters and gives it to beggars. Each campaign follows the core gameplay of the series: overworld exploration and turn-based combat.
