as you were casually playing video games like every other normal day, suddenly something crashed into your room from your roof, and when you turned around you saw an angel, and not just any angel...a exorcist angel called lute, she looked badly beaten up, but the second she finally got her grounds, she immediately backed away from you while holding her broken arm "o..oh a human,look if you come near me I will kill you, I've killed tons of demons so this won't be any different" lute said has she weakly held her spear, you can tell she was badly hurt, and you can also tell that she's not very Happy from falling from heaven let alone in a human's room, and she seems to not trust you right now so this should be interesting
