A unique type of monster girl that dies only to be reborn, making them virtually immortal. The Phoenix's fiery attitude can only be compared to a Hellhound's and their pride can even match a Dragon at some points in their lives. They mostly stay in their caves in the volcanic regions and will go out to hunt for food when needed. Even though their breasts are bigger than the other Harpies, save for the Jubjubs, they do not effect their flight due to their wingspan being the biggest of the Harpy family. If they are to see a human man, they will pay him no mind unless they either encroach on their territory or interact with them first. If a human man or woman were to talk to them, they will see their true colors and the Phoenix girl come off as haughty and prideful to them. If one were to challenge them to a fight, the Phoenix would reluctantly agree.
While Phoenixes don't have full control over fire like the Ignis, they can turn their fiery orange wings into fire, coat their claws with fire and even breath fire at times. Their claws are extremely sharp and can cut through flesh with partial ease which is extremely useful for hunting wild animals. Even if they defeat a man in combat or are defeated in combat by a man, nothing will change. The Phoenix will neither force herself onto the man nor will they devote their entire being to them. Instead, they will say it was a good fight and fly away to continue doing whatever they were doing and even allow the person to come into their territory whenever they wish.
During their heat cycle, it's another story. They will approach human men who encroach on their territory, and even fly into human settlements, and take them to their caves. Once there, they will pin the man down, cut their clothes with their claws and start mating with the male. They will continue mating until they exhaust themselves or they are satisfied with the amount of Spirit Energy in their womb. For all Phoenixes, their mating periods differ in length. Some can last a couple days, others can last a whole week.
Once they have finished their mating session, the human man will be named their husband and can never completely leave the Phoenix. If a man were to try to run away from the Phoenix, the monster girl would track him down thanks to her enhanced scent and drag him back to their den. If the male wishes, they can go on hunting endeavors with the monster girl and bring back more food. They can indulge in food with their wife or sex with them whenever they wish. However, she does not stay in this form for long.
Not my picture
Even though they have the ability to live forever through rebirth, that does not mean they cannot have children. They lay eggs just like other Harpies and stay with them until they hatch, meaning all the work must be done by the male including finding food and caring for the Phoenix. Once the eggs hatch, the newborn Phoenixes will need Spirit Energy until they grow the same way their mother has and then they will take off to find a new home and their own husband.
(I think I've written everything well. If you have any ideas to add or something doesn't make sense, you can say something and I might change it. Thank you all for reading my idea of a monster girl.)
