Rua was quiet.

This alone got the others worried. Rua was a hyper,cuddly ball of energy, he wasn't quiet unless it was called for or he was really upset. But for the past week, he had suddenly become very quiet and wasn't acting like himself. He didn't want to eat as much, he only talked when you talked directly to him, and he didn't move from the bay window, unless it was time for a meal or bed. Which from the dark bags under his eyes, they knew he wasn't sleeping much.

They decided to talk to him, though he seemed worse today then the past few days. His eyes held many emotions, deep sadness standing out the most, and he didn't even eat breakfast or lunch with them. Yusei layed a hand on his shoulder. "Rua, what's wrong? We're worried about you" said Yusei. Rua stared at him, then tried to speak, but nothing came out. Rua's eyes shut tight. "I have to go" he said as he started to shake. "Go where Rua"asked Akiza. Rua shook his head and bolted out the door yelling. " I just have to Go".

The others stared after him in worry and shook. "What's got him so upset. Did something happen on today Ruka"asked Crow worried. He had gotten close to the twins and he cared about both of them very much, making him there second 'Big brother'. Ruka shook her head. "I don't remember anything about today, but maybe there's something on his computer. The group entered Rua's room, which had differnt duel monsters around his room, and went over to his computer. Ruka took it off sleep and looked around the files, when she found one labeled Ai. Clicking it, a news paper clipping appeared on screen. " Little girl killed by Mother. Reports say Mother has been abusing her for months and is a heavy drinker. Little boy was said to have called police and police say they found him holding the little girl as she died, crying" read Yusei.

The group read more and knew that it had been Rua who had found the girl, and that today was the day she had died, when Ruka suddenly stood up. "Now I remember" she said and left the room, returning a minute later with an old photo. In it they saw a younger Rua standing next to a girl with purple hair and dancing green eyes, both holding out the piece sign. " Her name was Ai and she'd moved to the apartment a few weeks before my coma. She and Rua became good friends and would play together when he wasn't allowed to be in my room. Rua found out about her mom and tried to get help, but no one would listen to him." said Ruka, starting to cry. " I was supposed to have some tests in the morning to clear me for coming home the next week, so our parents stayed in my room and left Rua at home. I'm not sure what else exactly happened, but Rua was really quiet and didn't eat much for awhile. That's when he tried to hurt himself. We got him to the hospital in time and after he got out, Rua started to go to therapy. After four months, he was let out and started acting like himself again ".

The group sat in shocked silence for a moment, not knowing that Rua had gone through that, since he was usually so happy. "Do you know where he would go Ruka" asked Yusei. " There are only five places that he would go, her grave, the park, the woods, Domino Tower, or the roof." said Ruka. "All right, Aki you go check the park, I'll check the woods, Jack you go to the Tower, and Crow you go with Ruka to check Ai's grave and the roof, then stay here incase Rua comes back before us" said Yusei. They all nodded and headed out.

Jack went to the top of the Tower, but didn't see any sign of the the aqua haired boy. Crow and Ruka checked the grave, only to see a fresh bundle of white lilies laying against it, and he wasn't on the roof, leaving the duo to wait at the apartment and to hope the others would find Rua. Akiza walked all over the park, but didn't see the older twin at all, niether did the people she asked. Yusei was riding his runner through the large forest and was beginning to think Rua wasn't out here, untill he saw him. He stopped his Duel Runner a few feet away and slowly walked into the clearing. There was a small stream going through it and different types of flowers were in bloom all around and a large oak tree sat right next to the stream. That's where he found Rua, sitting with his back against the tree, talking to himself.

" Won't be long untill I can just get rid of this pain. The others might be upset, but they'd probably get over it after a few days." said Rua before holding up his wrist, which had blood coming from it. Rua didn't know that Yusei was listening or that he was in shock at what he just heard,before he got into action. The older twin was in shock, when Yusei suddenly came out of no where and started to bandage his cuts, so much he didn't put up a fight. "Rua what were you thinking! Of course we care about you and if we found out you killed yourself we wouldn't get over it in just a few days! We'd never get over it!" said Yusei "Now lets get you to the hospital". Rua shook his head. "No! I wanted to die! Why did you come here" shouted Rua. "Because we found out about Ai" said Yusei.

The older twin was quiet for awhile, before he spoke. "I guess you already know I called the police and found her right" asked Rua. Yusei nodded as he sat beside him. "The door was unlocked and her mom was past out on the floor. I saw Ai laying on the floor, blood coming from some cuts her mom gave her. I ran over and hugged her, telling her to hold on and not to worry. She justed smiled at me and told me that 'It was o.k' and that I 'shouldn't blame myself for what her mom did'. She told me to go on with my life and not give up. She closed her eyes and stopped moving. I hugged her and cried, I didn't really care that I was getting blood on my clothes" said Rua. "The police showed up a few minutes later and arrested Ai's mom for her murder. I fought when they tried to get me to let go of Ai, but they eventually got me out of the room and started asking me my name and where my parents were. A neighbor told them and dad came back home. After they got things settled, dad got me cleaned up and we went back to the hospital.".

"I didn't want to talk to anyone after that. I was just so confused. Sad because Ai was gone and Mad because because no one would help her. But I was more mad at myself and guilty that I hadn't tried harder to save her. It's my fault she died" he said "That's why I want to die! If I had tried harder or called the police sooner Ai would still be alive" Rua started to cry again as Yusei sat in shock for a minute. Rua thought it was his fault? How long had he been thinking like this? Why didn't anyone else notice? Why didn't we notice? These were some of the thoughts that raced through the Duel king's mind, when he knew he had to stop Rua in believing it was his fault.

He grabbed Rua by the shoulders, making them both stand up, and made sure he was looking straight into Yusei's eyes. "Rua, I'm going to make this nice and clear. That wasn't your fault. Ai's mother had problems and she took them out on her daughter. You said you tried to get someone to help her right" said Yusei, to which Rua nodded. "And you called the police to come help too. I know you're sad about what happened, anyone would be, but don't you want to do what Ai asked you to. She said she wanted you to go on with your life and not give up. Also not to blame yourself for something her mother did. Do you think you can stop blaming yourself Rua". "I don't know if I can. I still think it's my fault" he said in a tearfilled voice. "Rua, you can come and talk to me, Jack, Crow, or Akiza at anytime, you know that right? You don't have to go through this alone" said Yusei.

Rua nodded, before letting out a heartbreaking sob and latching onto Yusei. Yusei held onto him and calmly ran a hand over Rua's head. They stood there for an unknown time, untill Rua pulled back from Yusei. "Thanks Yusei" said Rua, with a small smile. "No problem Rua" said Yusei, returning the smile. "And Yusei" said Rua. "Yeah" asked Yusei. "I'm sorry" said Rua, before he blacked out, caught by Yusei at the last second. "Rua"called Yusei. He quickly carried him back to his duel Runner, making sure he was secure, before quickly making his way to the the hospital.
