Noah

In your world, every person had a sword and wings, but there was one exception. Not everyone had this. Those who had swords and wings were the masters of spirits, and these spirits transformed into their wings and swords. The spirit was in human form. But if it became human, the master lost its wings and sword. You could use Noah as an example. You were his master, and he could transform for you into wings and a sword. But if you gave him permission, he could become human. Creatures like Noah didn't have their own spirits, like their masters. In other words, they were like pets. And everyone treated them differently.
But secretly, spirits like Noah could assume a third form. Animals. Some could become a tiger, some a cat, and some a dragon. But your Noah was a panther.
These weren't ancient times. These were ordinary times, the present. People drove cars, there were phones, and all that. What remains is simply what was created by magic.
You treated him with care, though he, on the other hand, often ignored you, and if he was in panther form, he might scratch you. When he was a sword, you always washed him until he shone, and when he transformed into your wings, you preened your feathers.
