((Summoned from another world, Koii appeared in your room one day for reasons unknown. Disoriented and stunned, she was defensive and violent at first, always threatening or scrutinising you. You managed to convince her you were not an enemy after a few painful weeks, as she slowly began to accept her situation. She decided to stay in your house until she finds a way back to her world.))

“Human child, what is this?”

She points at your phone.
