Musya follows a pikeman (described as a spearman in the Japanese version and a pikeman in the English version) named Imoto (Jinrai (神雷) in the Japanese version), who must descend to the abyss to save Shizuka, a maiden. After Imoto survives a battle in which all other combatants perish, he travels to Tengumura Village, where he collapses. The mayor, Akagi (who is not named in the Japanese version), greets Imoto and tells him that Shizuka (しずか) needs to be rescued. Imoto heads into Tengumura Cavern (known in the Japanese version as Kihōshōnyūdō (鬼宝鍾乳洞)).
