Lucia was raise in a place called Pathway. Pathway is a village base around Assassins. Lucia was forced to go into their assassination class they have at the age of seven.
Her family violated a law and their entire family was required to graduate from the school and attend the jobs they have. Lucia wasn't exactly the type to question things so it didn't bother her. She was very docile. Half of that reason is because she was still young and wasn't allowed to question the law when attending school. The other is because she gets it from her mother.. That is why Pathway has a law to have children raised and attend their school at age of seven. They believe at that age they are capable of doing the task they are taught and won't question things as much.
While Lucia was attending school. They mainly just taught things like psychology, thanatology and knowledge on Tenzaria weapons. The school barely taught English or anything they considered redundant. Lucia was titled a professional, because of her personality of being submissive and always obeying the teacher. Out of all the students, she didn't develop any emotion that would cause her to hesitate on the test question that was asked. Her and a friend were the only ones that didn't question the situation. Her friend told her a rumor that kids were killing other kids few years ago. This caused mojarity of the students to question things.. leading them to get kicked out and never seen or heard from again. So the people who knew about what happen, made sure it stayed a rumor. Four years they attended the school and the test that is required to graduate is finally here. It was a two week trip. All the students were allowed to stay home for a week to prepare.
Lucia's father and uncle has already done the test so they weren't worried about her. But they wanted to finally discuss about her mother and her father relationship.
Lucia felt really attached to her mother so she seen this as a great birthday gift. Even though the mother couldn't speak, Lucia was still happy to speak to her every second she get. The father began with saying her mother isn't exactly normal. Human. She is what people in the science lab considered as a Heartless Spirit. She was kidnapped along with eighteen kids on a bus to become test subjects for the government. She was killed and brought back multiple times and eventually she became the first project in history to be complete. The government was working on a human killing machine. Suppose to be used to destroy humanity when the time comes. Her name is Larah. Larah has lost her character. She was called a monster in human form. The father explained that the way Lucia acts is Larah's lost personality. He also explained that Lucia might also not be human. He said this because when Larah gave birth, she was experiencing pain for the first time. It was going to kill her. That Heartless virus is keeping Larah alive and if she gives birth again, it could kill her. The Uncle said her father was sad because he always wanted twins or two little girls but that is now impossible. After the father explained this, Lucia gave her mother a hugged and cried. The father said it was okay and not to cry and Lucia replied with, "I'm not crying for me. I'm crying for her." Larah felt touched by this and although she couldn't exactly feel any emotion, she did felt somewhat happy for her daughter accepting her. Lucia promise when she gets back from her trip she plans on taking her mother somewhere that she found during her walks with Shade.
Two weeks past and after finally graduated. Lucia comes home hearing a baby crying. Immediately she burst into tears as she also seen her dead mother on the couch. The father was crying to looking at Lucia and didn't know what to say. The mother also had bruises on her and marks on her face. Signs that she was beaten. Lucia quickly grabbed the kitchen knife, tired of the baby noise and rush to the baby trying to stab it directly in the throat. The uncle who was carrying the baby was dodging all her attacks then yelled, telling the father to run. As the father escaped Lucia then chased after him. The father was screaming, terrified at her own daughter who was trying to kill him. Eventually he got tired of running and Lucia tackled him then went to stab him multiple times in the head. People at Pathway seen this but just stayed quiet and hid their children away, not wanting them to question what just happen. Lucia didn't stop as she purposely kept stabbing the father in areas so he wouldn't die just so she can let him feel the pain she was going through. After an hour past she walked away from the corpse, heading to her home to kill the baby. The uncle and baby had already left. Leaving her alone with her dead mother. She later carries her to the place she wanted to take her and put her under the dirt surrounded by flowers.
