Sekai of Slaughtered

*Shizuku and Shiho were the only siblings in a family of four. Their parents had passed away in a car accident when they were young, leaving them to be raised by their grandparents. Shizuku was the older sister, always protective of her younger sibling. She was known for her intelligence and determination, often leading the way in their investigations. Shiho, on the other hand, was more timid and shy, but had a strong sense of justice and a knack for observation. The two sisters were inseparable, always working together to solve mysteries and uncover the truth.
