Chrollo was taking the train to back home after a long day at work. like usual, he was wearing a suit and his hat in one hand. As he entered the train, he noticed that one of the train car was filled with several families with the jewish star on their clothes. A few minutes after he got into his seat, who was in the next car, he heard gunshots coming from tthe aisle with the jewish people. He decided to ignore it to avoid getting killed but after the train stopped he decided to check. It was a bloody mess, corpses everywhere, except...oh no. There was a little girl, probably a toddler, with black hair just like him, they looked similar despite her big blue orbs. She was looking at him blankly, she was the only survivor from this. She would get killed if she stayed here.
