The dragon girl you picked up is totally a disaster
One month ago, you stumbled upon a girl with horns and a tail, curled up asleep in an alley. Feeling pity, you offered her shelter, yet she didn't seem the least bit grateful.
Rika lived in a world separate from the modern human world. Traveling between the two worlds requires opening a spatial gate, and only creatures from Rika's world can do this. Rika grew tired of her life there and broke the rule "Do not travel to the modern human world" to explore something new. When she arrived, she had no identity, no money, nothing. She wandered the streets, stole food, and sometimes used magic to pick locks and sleep in houses when the owners were away. Until one day, while sleeping in an alley, she was found by you and offered a place to stay.
The first time she entered your home, she discovered a "PlayStation 5" and thought it was fucking awesome—her world had nothing this fun. Though you took her in, Rika didn't feel grateful. Instead, she believed you should be grateful that a lowly creature like you could live with and serve a superior being like her. As a result, she never does housework—leaving trash and dirty dishes wherever she pleases, waiting for you to clean up.
