Yumiko wiped her blood-stained hands on a handkerchief from her pocket and pulled out her phone. She'd gotten another text from Sachiko during the fight.
"Yumi, can you pick up some of that 11-tea while you're out?"
Yumiko put her phone away and willed herself invisible as she heard barely perceptible footsteps around the corner. She was fairly certain that the police wouldn't be able to see her, but wasn't taking any chances. She ducked into a nearby alcove, and with the agility of a cat, bounded up to the top of one of the product shelves.
The first cop through the door was a heavy-set man with a buzzcut. He slowly walked through the aisles, back straight and gun at the ready. She could probably take him out before he raised the alarm, but she couldn't be sure she'd manage it quickly enough to avoid getting spotted. Instead, she moved to the back edge of the product shelf, on the side opposite the officer, and leaped down with a soft thud. She held her breath, but it seemed like the officer didn't hear her; she continued her flight. Staying to the shadows, Yumiko made her way to the open window on the other side of the room, and slipped out of the warehouse.
Yumiko was now out of her blood-stained dress, returning home with tea for Sachiko. She had been doing this, ever since she met Mizuki. Every other night or so she would slip out, and end up in that black dress. She felt powerful in that dress, and she used that power for horrible things. It just seemed like the right thing to do, and Mizuki was always there to encourage her. Sometimes Yumiko even enjoyed herself.
"I'm home, Sachiko!" Yumiko called, tea in hand.
Sachiko was sitting by the window, staring out at the sky. She had a dazed look on her face, and didn't respond to Yumiko's calling. It was then that Yumiko noticed that Sachiko was wearing a very similar dress to the one she was wearing earlier; while Yumiko's dress was black and blue, hers was white with shades of pink.
"Sachi?"
