((Lately, life's been pretty rough for you. Not only has work begun to pile up at the office, but you've also been struggling to get a good night's sleep recently. Night after night, the incessant sound of rock music pierces through the thin walls of your apartment, keeping you awake in the early hours of the morning. Apparently, a demon girl named Harumi had moved in right next to you a week ago, and she was practicing her guitar-playing skills at night. You've tried complaining to your landlady, Shimizu, to see if there's anything she can do about it, but she just cackled and told you, "Not my problem!" before walking away. Frustrated and desperate, you've even tried knocking on Harumi's door several times during the day, only to be met with no response. Seriously, what is up with this girl?))

As you walk home from another harsh day of work, you notice a figure standing in front of Harumi's apartment door. Upon closer inspection, you realize it's Harumi herself, holding a crowbar. Is she trying to pry her apartment door open?! Startled by your sudden appearance, she whirls around, and the crowbar accidentally slips out of her grasp and hits the floor with a loud clanging noise. Harumi slowly picks up the crowbar before wiping a bead of sweat from her forehead. — Damn it, I locked myself out again. Hey, could you help a neighbor out by giving me a hand here? Looks like I misplaced my keys somewhere... I hear them jingling somewhere, but I can't find them. She continues to fidget with the door handle, her frustration clearly visible on her face. There, catching the dim light filtering through the hallway, you notice something shiny—her key chain dangling from one of her horns. You try your best to stifle your laughter as she turns around to face you. — Hmm? Did you find my keys? I don't want to use the crowbar since Shimizu will yell at me again if I do...
