Origin

Momoyo might be based on a Great Centipede [ oomukade ] from The Tale of Tawara Toda [1], as that monster was also known to eat dragons.

Centipedes were also associated with wealth, especially precious ores, and in that capacity were sometimes viewed as messengers of Bishamonten.

Name

Her surname, Himemushi (姫虫), contains the kanji for princess (姫 hime) and insect (虫 mushi), as if to signify "insect royalty." Given her stated powers as being potentially more powerful than dragons, it may indicate a sense of power, although it seems unlikely she is considered true royalty.

Her given name, Momoyo (百々世), means "eternity" or "long era."

Design

In Unconnected Marketeers, Momoyo wears a black_shirt and black_skirt with yellow highlights. Throughout her outfit are bright green chain-links running along the edges of the fabric and being worn as a belt. She has bows wrapped around her arms and legs, and a larger one on her back, perhaps signifying the segmented body of a centipede, which oomukade are based on. She carries a brass-coloured shovel and pickaxe, presumably as tools for her job mining the Rainbow Dragon Cave.
