The Luminous Fairies and Mothra
The Luminous Fairies and Mothra (発光妖精とモスラ) is a serialized novel written by Takehiko Fukunaga, Shinichiro Nakamura, and Yoshie Hotta. Originally serialized in Weekly Asahi and later collected in paperback form, the novel was the basis for the 1961 film Mothra and is the first appearance of the kaiju Mothra. Not much is known about what differences from the finished screenplay it may have had, except that the fairies were called Airenas and there were more than two.
Synopsis
An expedition to a quiet island in the South Pacific finds a marvel of modern science living amongst the island's tribe. Several fairies called the Airenas live in peace, adoring their Goddess, Mothra. The expedition steals the fairies away to America, angering the island's Goddess. Mothra hatches from her egg, travels through the South Pacific and arrives in Japan. After unintentionally causing damage, she metamorphoses into her adult form, and flies to America. She obliterates the city where the fairies are being held, rescues them, and returns home to live out her life in peace and harmony.
