Getsu Fuuma Den

Getsu Fūma Den (月風魔伝) is an action RPG game for the Famicom by Konami, released in 1987. The lead character, Getsu Fuuma (whose name can be translated as "Lunar Wind Demon"), is based on the real life 16th century ninja Fuuma Kotaro. The box features artwork printed on a lenticular card which makes the image change depending upon the angle it is viewed from. This game was never released outside of Japan, although the legendary translation group RPGe has translated the game into English. The patch to translate the game, which was released in late 1998, can be found here. A hack-and-slash "roguevania" sequel, titled Getsu Fūma Den: Undying Moon, was released on the Nintendo Switch on February 9, 2022 and left Early Access on Steam on February 17.

The player controls Getsu Fuuma, who travels through the overworld on pre-determined paths, which often branch off, leading to shops, character areas, and dungeons. Once in a dungeon, which is usually marked on the map with a torii (traditional Japanese gate), the player can navigate Fuuma through traditional platform action, jumping and attacking enemies with a sword or other weapons. There are also first-person dungeons later in the game. Throughout the game, the player can collect money and then use it to buy weapons and other accessories on the overworld.

Getsu Fuuma Den resembles the 1986 Namco arcade game called Genpei Tōma Den. The "Underworld" concept, characters, and gameplay are very similar in both games. Although there hasn't been any remake or sequel done by Konami yet, Fuuma has appeared as a playable character in the Wai Wai World franchise (where other Konami characters made an appearance as well). In the Yu-Gi-Oh! Trading Card Game, Getsu Fuuma and his enemy, the Dragon Master, also appear as cards. The English versions of the cards are called "Getsu Fuhma" and "Ryu Kokki."

Story
The following is a translation of the game's opening story:

"'In the first years of the Demon Age（A.D.14672）, a horrible demon named 'Dragon Master' was revived by his minions in hell. To protect the peace of the overworld, the two eldest Fuuma brothers fought the Dragon Master. Both were unable to defeat him and were killed, losing their legendary Wave Swords, also called Hadoukens. To avenge their deaths, the last of the Fuuma brothers vowed to slay the Dragon Master, and take back the Hadoukens.'"
