Mach Harpies are a race of harpy with the ability of going extremly fast. They can dive at ten mach (ten times the speed of sound) and cruise at 6 mach, henceforth the name Mach Harpy. They achive this by a mixture of clever evolution and magic. Their wings, hair, and back are covered in a sheet of black feathers that create almost no friction with the air around it. It also is able to withstand the high tempertures that are created when you fly really fast. But to protect the parts of the body not covered with feathers, they have a strange enchantment with in them. The feathers seem to absorb all the heat around it's body. So in a desert, just by standing next to them, it is possible the heat won't affect you as bad. One part of their body not covered with feathers but resistant to the heat is their talons. Up to the knee is a special black metal-like boot . It is not actually a boot but a special scale like substance that not only abosorbs heat from the fiction caused by the feet but also to abosob the impact from landing. On the bottom are some blue claws that have lots of grip. That causes problems for Mach Harpies when they fly so they leave it right out behind them. That way it causes less drag.
They acheive high speeds through their biology, magic, and nature. First they fly high enough that they won't crash if they go down hill. An impact at such high speeds would kill them, adapted or not. They have to be at a minimum hight of twenty-thousand feet just to get started. They must go even higher just to reach their top speed. That creates another problem for the Mach Harpy: getting oxygen. They have advanced lungs that can breath easily at high altitudes but when they are at layers with barily any oxygen they turn to a special organ in their body. It is two pouches right in front of their lungs that store oxygen for their body to use. What it appears to look like is their breasts are expanding. This doesn't effect them because for them to need to do that they would be in such high altitudes for it not to matter. Also they exhale the used air. To reach even higher speeds (up to six mach) they have to use magic to accelerate themselves through the air. To top this even they have a coat of paper thin magic that covers their entire body to make even the featherless areas have very little friction. And to reach their maximum speeds (ten mach) they dive while activating all their other abilities.
A Mach Harpy has a generally bold and brash personality. They belive they can escape from any problem by flying. While that is true for earthly problems, emotional problems they can't escape from. That makes Mach Harpies very emotionally unstable. They are very fun loving and will prank many other mamono by stealing and flying away. They are not thiefs however and will return all stolen loot. They love doing dares and stunts often showing off to their husbands and friends. Sometimes one goes so fast their feathers heat up and glow red. This is considered a great achievment in Mach Harpy culture.
Mach Harpies are very clumsy when it comes to mating. Their bodys will often slide right through their husband's grip. On land they are often clumsy and nothing like in the air. To try to solve this problem they will often work in groups to mate. Some holding them together while one engages them. But getting a husband is a huge task what so ever. If they find a human man they like they'll take him, but they are very picky and often have to look far and wide to find a man. If they still can't find one they will do something terrible for a mamono. Mach Harpies will steal husbands from other mamono. They will grab one and fly. Considering how fast they fly they usually get away with it. Many however after spending a week with the man start feeling guilty and return him. This means many don't have husbands. Some Mach Harpies have stolen many men just to have a couple of children. Some heartless (Not un-loving just un-caring) have made stealing husbands a game. Almost always though a husband is returned.
They live on mountains because it is easier to accelerate. Other times they live in deserts. That is so they can catch thermals righing off the ground to go up high really fast. Many however are nomadic. They always move around. They do this to find husbands, and once they find one they settle down to raise a family. They will accept harems gratefully if the husband is to their liking.
