Shobijin

The Shobijin, which translated means "small beauties", are twin fairies that hail from Infant Island in the Western Pacific Ocean. Always speaking in unison, they are the representatives of the island's guardian - the giant kaiju known as Mosura.

In 1961, an expedition leader from Rolisica named Clark Nelson kidnapped two Shobijin and planned on exploting them for his own personal gain. This act awakened the rage of Mosura, who attacked first Tokyo, then New Kirk City in Rolisica. With the help of a scientist named Shin'ichi Chûjô, they succeeded in reuniting with Mothra and returning to Infant Island.

Forty-some years later, a different pair of Shobijin visited Chûjô's home in Karuizawa. Aware that Japan's SDF forces had used the bones of the previous Godzilla in the construction of their MechaGodzilla defense robot, they implored with Chûjô to convince the Japanese government to return Godzilla's bones to the sea, or else Mothra will see this as a spiritual effrontery and attack Tokyo again.
