This is dark but I want to explain why Keiko is like this and don't worry the father is going to get his just desserts, I just don't know how yet.
Keiko Past
Izumi woke up to find that she was in a hospital. It only took a second before bolting up looking around the room. "Keiko where are you little one?" Izumi yell, as the door to the room open up. Edward came in as Izumi try to get out of bed. "Save your energy Sensei, you been out of it for a couple of hours. I called Sig for you; he should be here anytime soon." Ed said, as he sat on the edge of the bed. Izumi lay back down and sighed. "Where Keiko Ed?" Izumi asked as she stares up at the ceiling. "She with Al and a nurse Sensei. I need to talk to you about her." He looked down at the floor.
"We search his house again and found a wall that looked different from the others. We thought he might hide the money in his house but when we torn the wall down we found two skeletons. One adult female and one female child…It took hours of questioning him but we finally got a story on who they were." Ed goes up and went to the corner of the room looking away. Izumi sat up while turning her head to follow. She could swear that he was crying. "Edward who were they?" "They were his wife and Keiko twin sisters. One day while beating Kiyone, Keiko twin sister he went to far and nearly beat her to death. It was then that his wife came into play…She was trying to protect Kiyone and he hit her on the head knocking her out." Ed said, banging his fists on the wall. Izumi got up and went to Ed placing a hand on him. "Please tell me the rest of the story Edward." Ed turns around to face Izumi, to see that she was still wearing her blood soaked clothes. "Let go sit back on the bed Sensei." Ed said, while they went back and sat back down. Ed stares at the wall across the room. "You know they were still alive when he put them behind the wall. He even made Keiko help him do the brick lying. They survive for about a week, during that time he and Keiko could hear them screaming and clawing at the wall, trying to get out. Then one day early in the morning it stopped, Keiko during that time try to help but every time she got near the wall he would grab her by the hair and beat her. It happens about over a year ago, she was only three years old when it happened." Ed put his hands together as Izumi look at him. "How could that sick bastard do that to his family?" Izumi said, she was white as a sheet but it was more from shock than her illness.
"You know her mother name was the same as yours Sensei. He told me that she would wake up crying and to shut her up beat her till she stopped." Ed got up as the door open up to see Al and Keiko. Keiko ran to Izumi, hugging her hard. "Mrs. Izumi I was so scare." She was crying as she buries her face in Izumi chest. Izumi held her as she let her cry. "I'm alright little one, I just had a little attack that all." Izumi said softly, she lay down on the bed as she put Keiko in the middle of the bed, rubbing her back Izumi started to sing a lullaby. Ed and Al went to the door and before leaving Ed turn around to look at Izumi. "I'll come back later Sensei." Ed whisper as he and his brother left. Izumi stop singing and try to speak to Keiko as she stopped crying to look at Izumi in the face. She tries so hard to ask Keiko questions but she could bear to make her relive anymore painful memories. They stayed like this for what seemed like forever. Keiko fell asleep as Izumi watch her. If she could just get near him she would make him suffer for the evil things he did to Keiko. Izumi fell asleep with that in mind.
