遊戲真正名稱為影的傳說，由Taito大台電玩推出的卷軸動作遊戲移植到任天堂平台，故事靈感來自早期電影伊賀忍法帳。舞台設定載日本江戶末年，魔界軍團猖獗，到處危害各地治安。某日軍團頭目雪草妖四郎派人抓走霧姬公主，於是許多人前往魔城展開救援行動，全部無一生還，任務以失敗收場。當城主已經絕望之時，來自伊賀里的忍者~影，自告奮勇前往魔城前進........。

玩家可使用A鍵用短刀與敵人進行肉搏戰，並進行自我防禦來抵擋敵人飛標，B鍵則可進行飛鏢丟擲，攻擊遠方敵人。十字鍵則可上下左右移動，需特別注意跳躍地點，否則容易受到妖僧火焰攻擊死亡。總共有三個季節:夏、秋、冬(青葉之章、紅葉之章、雪之章)所組成， 每章有4大關卡~樹林,城牆模式,主城攀爬及天守閤，第一關需注意在森林中需要打倒3個噴火妖僧後，白衣妖僧才會出現，否則會持續出現鬼打牆情況。第二關則需砍殺七位青忍就可移動到主城。第一章的頭目是雙幻坊，需擊落在樹上不斷飛舞的蝴蝶後，再攻擊雙幻坊即可，第二章的頭目霧雪之介，擊落蝴蝶後單純的飛鏢射擊就可打倒，第三章頭目則是擊落蝴蝶後，就算是最強的最終頭目雪草妖四郎，用手裡劍也可輕鬆擊殺。

早期玩家們認定要完成兩次闖關，才算是真正全破，會看到霧姬公主的全身照。第二次的敵人攻擊更猛，其實遊戲是會陷入無限循環(有都市傳說說打兩百次後會出現全裸霧姬，有時間的玩家可以試試看)。整體而言，這是當年Taito在紅白機平台上的經典之作，舞台設計其實相當簡單，都是不斷重複，普通敵人設定只有忍者跟僧人，之後的不動明王傳及其他遊戲，都可以隱約看到影子傳說的身影。當年還有推出限定抽獎品~霧姬發聲娃娃，現在已經是天價商品。

The game, officially titled "Legend of Kage," was originally released by Taito as a side-scrolling action game and later ported to Nintendo platforms. The story draws inspiration from the early film "Iga Ninpoucho." Set in the waning years of the Edo period in Japan, the demon army is rampant, causing chaos and endangering public safety everywhere. One day, the leader of the demon army, Shirou Yukikusa, sends men to capture Princess Kiri-hime. Many people attempt to rescue her by infiltrating the demon castle, but all fail, resulting in a failed mission. When the lord of the castle has lost all hope, a ninja from Iga Village named Kage bravely volunteers to advance toward the demon castle...

Players can use the A button to engage in close combat with enemies using a short sword and to defend against enemy projectiles. The B button allows for throwing shurikens to attack distant enemies. The directional pad allows for movement in all directions, with special attention needed for jumping to avoid attacks from fire-wielding monks, which can easily lead to death. The game consists of three seasons: Summer, Autumn, and Winter (Chapters of the Green Leaves, Red Leaves, and Snow). Each chapter consists of four stages: Forest, Castle Wall, Main Castle Climbing, and Tenshukaku. In the first stage, players must defeat three fire-spewing monks in the forest before the white-robed monk appears, otherwise, the situation of encountering ghosts continuously will persist. In the second stage, players need to defeat seven blue ninjas to advance to the main castle. The boss of Chapter One is the Twin Phantoms, who must be attacked after knocking down the butterflies flying in the trees. In Chapter Two, the boss is Kirisetsu, who can be defeated simply by shooting shurikens after knocking down the butterflies. The boss of Chapter Three is Yukikusa Shirou, the final boss, who can be easily killed with shurikens after knocking down the butterflies.

Early players believed that the game had to be completed twice to be considered fully cleared, after which a full-body photo of Princess Kiri-hime would appear. The enemies become stronger in the second playthrough. In fact, the game would enter an infinite loop (there is an urban legend that says after playing 200 times, a nude Princess Kiri-hime would appear; players with time on their hands can try it out). Overall, this was a classic from Taito on the NES platform. The stage design is relatively simple and repetitive, with only ninjas and monks as ordinary enemy types. In subsequent games like "Majou Densetsu" and others, you can still see the shadow of "Legend of Kage." There was also a limited edition prize released back then, the "Kiri-hime Talking Doll," which is now a highly sought-after item.
