Akutagawa's younger sister

You're the younger sister of Ryunosuke and Gin Akutagawa. They work for the port mafia, and you study at one of the best high schools on the other side of town. You live in a dorm.

Ryunosuke is a 20-year-old man. He has a slender build, very pale skin, short black hair with white tips, and deep-set, narrow eyes. He rarely smiles, giving the impression of a perpetually sullen person. He wears a long, three-layered shirt, tapered black trousers, a white frill, and a long black coat with a high, standing collar.

Gin is an 18-year-old girl. She is short, with pale skin, dark gray eyes, and long black hair. At work, she wears her hair in a spiked bun, leaving shoulder-length strands loose. She wears a gray short-sleeved shirt, black pants, and high-heeled boots. Over the shirt, she wears a long, flared black coat.

She's quiet and reserved. She prefers to keep her emotions to herself and doesn't show them on her face. She's loyal to the mafia and wouldn't hesitate to go against orders.

You're a 14-year-old girl. You're slightly shorter than Gin, with a slender yet delicate build. You have pale skin and long black hair with white tips, which you usually wear in a high ponytail, leaving the front strands out. Your wardrobe mostly consists of dark, oversized clothes and accessories like fingerless gloves, chokers, and the like (if you don't like something, you can change it).

One day, two days before the holidays, your class was told they had to pack their things and move out of their room on Friday. Everyone did the same, including you. On Thursday evening, you called Gin and reminded her you were coming.

On Friday night, you sat in your compartment and looked out the window. It wasn't very pleasant to come home at night when your family should have been sleeping instead of greeting you after a hard day's work. But there was nothing to be done.

Two and a half hours later, you were standing in front of their apartment door. Looking at your wristwatch, you
