On a perfectly normal day, Chris Thorndyke's rich parents, Lindsey the actress and Nelson the businessman were about to brutally murdered in a gruesome car crash by the evil Sephiroth. Sephiroth drove a huge car all throughout the mansion and the ensuing collateral damage also took the lives of his scientist grandfather Chuck, maid/chef Ella and butler Tanaka.
Before it happened, Chris's parents looked out of the window of their mansion and said to Chris in a panicked tone, "Run for your life!"
As soon as it all went down, it was too late for all except Chris. He managed to escape with his life, but no one else could. After the mansion was destroyed and everyone was close to being killed, Sephiroth plotted to finish the job by taking Chris's life as well by running him over. However, Cloud Strife and Tifa Lockhart came to the boy's rescue. They advised him to hide while they dealt with the killer.
During a lengthy battle, Cloud repeatedly slashed Sephiroth with his Buster Sword while Tifa kept punching and kicking him. Unfortunately for them, Sephiroth not only took too little damage, but dealt a little too much damage to Cloud and Tifa. As a last resort, Cloud used Omnislash and slashed him so many times that he lost count, he slammed the Buster Sword against him in a huge explosion, rendering Sephiroth unconscious.
Once the battle was over, Chris came out of hiding and was looking as the twisted and mangled bodies of his caretakers, all of them were about die. Chris asked, sounding very worried, "Mom! Dad! Don't worry, I'll call an ambulance!"
Lindsey said weakly, "Don't bother, Chris. Our injuries are probably too severe We might not make it, we might no longer laugh, cry or get angry."
Tears welled up in Chris's eyes that were burning, his fingers were tingling and his mouth was dry as he desperately said, "No! I'm sure they can save you! I know they can do something!"
To make matters worse, Sephiroth suddenly stabbed both Lindsey and Nelson with his sword as a final warning to Chris that he was next. Sephiroth warned them all, "You win this round, but I'll be back. I will not rest until all of you are dead, then the rest of the world will be wiped out!"
After Sephiroth left, Cloud and Tifa called an ambulance on Chris's behalf and accompanied the poor boy at the hospital. Chris's parents, grandfather, maid, and butler were rushed to the nearest hospital. Sadly for Chris, none of them could be saved from certain death. The doctors and nurses told him that there was nothing they could all he could do was say goodbye. With the five adults on their death beds, Chris wept as Nelson consoled the orphan to be, "Be brave, son. Everyone has someone that's after them. We might be gone, but we will be with you forever...in your...heart..."
Finally, everyone flatlined, Chris was devastated and felt his heart break in half after seeing that everyone he loved has died. Now that he was an orphan, he cried a bit as he silently asked himself, "What am I going to do? Where am I going to live?"
As Tifa and Cloud saw that Chris is sad, Tifa and Cloud made a decision, they put their hands on Chris's shoulders and said, "We'll take care of you."
Chris was surprised to hear that and sniffled, "You will?"
Tifa comforted him, "You won't need to move anywhere. We'll move into your mansion and rebuild until it's good as new."
Cloud added, "We'll be your new family."
The boy hugged his new parents and said, "Thank you both very much. This is most generous thing anyone has ever done for me."
After they left the hospital, Cloud and Tifa went through quite a bit of paperwork to legally adopt Chris and raise him as their own. Once Chris became their new son, they hired a construction crew to rebuild Chris's destroyed mansion until it looked like Sephiroth never wrecked it. There were even a few upgrades like new appliances and refurbished rooms.
Now that Chris's mansion was fixed, Chris, Cloud and Tifa set up a little memorial in the backyard for not only Chris's deceased family members, but also Aerith Gainsborough. They placed a few flower bouquets in front of pictures of those they lost.
At night, Chris went to bed as Tifa assured him that everything would be fine and they would never let anything happen to, Chris said, "I love you, Tifa."
Tifa mentioned, "Please, call me mom."
"I love you, mom."
"I love you too, son."
