Extra boss of Unconnected Marketeers. An oomukade (“giant centipede”) capable of eating dragons.
Momoyo has long, messy grey hair and grey eyes. She carries a gold pickaxe on her left and a gold shovel on her right. She wears a matching shirt and skirt combo, and goes barefoot. Her limbs are adorned with many orange bows, while her clothes have many rings attached to them.
A dragon-slaying centipede princess, she was approached by Megumu for a job mining the dragon gems. Unusually among Touhou characters, she refers to herself with the masculine personal pronoun "ore". Also notable is how she is one of the few characters in the series without a hat or head accessory.
