-A week later-

It's been a week since Tsuna did her first recording of her Album Sky and they quickly sold when they were put out. Right now she is at the Rainbow Star Studio in the room that she was given. The room has a queen canopy bed with a see through canopy curtain, a desk, a black couch, two sofa chairs, a flat-screen TV, a mini kitchen bar and a bathroom attached to the room.

Tsuna is sitting on the black couch while writing a new song in her songbook. Then there was a knock on the door. "Come in." She called as she closed her songbook.

The door was opened to reveal Byakuran, who was smiling at her. "Oh Tsuna-chan.~" He called out in a sing-song voice.

Tsuna smiled at Byakuran. Over the last week, they have been hanging out and getting to know each other. "Hey Byakuran-kun." She greeted him with a smile as he came into the room.

Byakuran sat down by Tsuna and smiled a bright smile at her. "You know I find it funny that a female Tsuna who's going to be Vongola's Decima in the future has became a singer for a recording label that is apart of the Mafia."

Tsuna looks at Byakuran confused. "What are you talking about?"

Byakuran then went on explaining on how he has the ability to see parallel worlds and that all the parallel worlds that he has seen, either she be a male or a female, she would end up being the Tenth Vongola Boss. He then went on to tell her about the mafia and the Dying Will Flames that Mafiosos use.

"Wow." Tsuna said in shock at what she has just learned. She then smiled at Byakuran. "Well if I am destined to be the Tenth Vongola Boss, I know that you will be by my side. Right, Bya-kun?"

Byakuran smiled at Tsuna. "Yeah, I'll always be by your side." He told her. He vowed then that he would never be anything like how his parallel selves are like, that he would never want to obtain the 'Ultimate Power' like them.

Tsuna smiled at Byakuran.

-A year later. Tsuna, age 12-

It's been a year since Tsuna became the singer known as Sora Doragon, met and became friends with Byakuran and finding out about the Mafia. Byakuran would always visit every weekend if he wasn't busy and his visits are always surprise visits.

Tsuna is in her room at the Rainbow Star Studio and she is sleeping on her bed. She was tossing and turning around in her sleep as she was having a nightmare about her past life.

Harriet was leaning against the hedge, gasping for breath and looking around. Cedric was standing feet from Triwizard Cup, which was gleaming behind him.

"Take it, then." Harriet panted to him. "Go on, take it. You're there."

But Cedric didn't move. He merely stood there, looking at Harriet. Then he turned to stare at the cup. Harriet saw the longing expression on his face in the golden light. Cedric looked around at Harriet again, who was now holding onto the hedge to support herself. Cedric took a deep breath.

"You take it. You should win. This is twice that you have saved my neck in here." Cedric told her.

"That's not how it's supposed to work." Harriet said to her crush. Her leg was very painful, she was aching all over from trying to throw off the spider and just wants all of this over with. "The one who reaches the cup first gets the points. That's you. I'm telling you, I'm not going to win any races on this leg."

Cedric took a few paces nearer to the stunned spider, away from the cup, shaking his head. "No."

"Stop being noble." Harriet told him, irritably. "Just take it, then we can get out of here."

Cedric watched Harriet steadying herself, holding tight to the hedge. "You told me about the dragons." He said. "I would've gone down in the first task if you hadn't told me what was coming."

"I had help on that too." Harriet snapped, trying to mop up her bloody leg with her robes. "You helped me with the egg... we're even now." She testing her leg, it shook violently as she puts weight on it, she had sprained her ankle when the spider had dropped her.

Tsuna was still tossing and turning in her bed when the door to her room was opened by a very happy Byakuran. He quickly got serious when he saw that his friend was tossing and turning in her sleep, meaning she was having a nightmare.

"You should've got more points on the second task." Cedric said mulishly. "You stayed behind to get all the hostages. I should've done that."

"I was the only one, who was thick enough to take that song seriously!" Harriet said bitterly. "Just take the cup!"

"No." Cedric told Harriet. He steps over the spider's tangled legs to join Harriet, who stares at him. Cedric was serious. He was walking away from the sort of glory Hufflepuff House hadn't had in centuries. "Go on." But he was looking as though this was costing him every ounce of resolution he had but his face was set, his arms were folded, he seemed decided.

Harriet looked from Cedric to the cup. For one shining moment she saw herself emerging from the maze, holding it. And then the picture faded away and she found herself staring at Cedric's shadowy, stubborn face.

"Both of us." Harriet said as she looked at Cedric.

"What?"

"We'll take it at the same time. It's still a Hogwarts victory. We'll tie for it."

Cedric stared at Harriet. He unfolded his arms. "You... you sure?"

"Yeah." Harry said. "Yeah... we've helped each other out, haven't we? We both got here. Let's just take it together."

For a moment, Cedric looked as though he couldn't believe his ears, then his face split into a grin. "You're on." He said. "Come here."

Cedric grabbed Harriet's arm below the shoulder gently and helped her limp toward the plinth where the cup stood. When they had reached it, they both held a hand out over one of the cup's gleaming handles.

"On three, right?" Harry said.

"One... two... three..."

Harriet and Cedric both grasped a handle. Instantly, Harriet felt a jerk somewhere behind her navel. Her feet had left the ground and she could not unclench the hand holding the Triwizard Cup, it was pulling her onward in a howl of wind and swirling color, Cedric at her side.

"No. Please no." Tsuna whimpered out as she tossed and turned. Byakuran ran one of his hands through Tsuna's hair, trying to calm her down as she keeps on having her nightmare.

Harriet felt her feet slam into the ground, her gave way and she fell forward to the ground, her hand let go of the Triwizard Cup at last. She then raised her head to see where they are at.

"Where are we?" Harriet asked.

Cedric shook his head, he got up and then pulled Harriet up to her feet. They then looked around. They had left the Hogwarts grounds completely, they had obviously traveled miles, perhaps hundreds of miles... for even the mountains surrounding the castle were gone. They were standing instead in a dark and overgrown graveyard, the black outline of a small church was visible beyond a large yew tree to their right. A hill rose above them to their left. Harriet could just make out the outline of a fine old house on the hillside.

Cedric looked down at the Triwizard Cup and then at Harriet. "Did anyone tell you the Cup was a Portkey?" He asked.

"Nope." Harriet said. She was looking around the graveyard. It was completely silent and slightly eerie. "Is this supposed to be part of the task?"

"I dunno." Cedric said. He sounded slightly nervous. "Wands out, don't you reckon?"

"Yeah." Harriet was glad that Cedric had made the suggestion rather than her.

They pulled out their wants. Harriet kept looking around her, she yet again has the strange feeling that they were being watched.

"Someone's coming." Harriet suddenly said.

Squinting tensely through the darkness, they watched the figure drawing nearer, walking steadily towards them between the graves. Harriet couldn't make out a face but from the way it was walking and holding it's arms, she could tell that it was carrying something.

Whoever it was, he was short and wearing a hooded cloak pulled up over his head to obscure his face. And several paces nearer, the gap between them closing all the time... Harriet saw that the thing in the person's arms looked like a baby... or was it merely a bundle of robes?

Harriet lowed her wand slightly and glanced sideways at Cedric. Cedric shot her a quizzical look. They both turned back to watch the approaching figure. It stopped beside a towering marble headstone, only six feet from them. For a second, Harriet and Cedric and the short figure simply looked at one another.

And then without warning Harriet's scar exploded with pain. It was agony such as she had never felt in all her life, her wand slipped passed her fingers as she placed her hands over her face, her knees buckled, she was on the ground and she could see nothing at all, her head felt like it was about to spilt open.

From far away, above Harriet's head, she heard a high cold voice say. "Kill the spare."

A swishing noise and a second voice, which screeched the words to the night. "Avada Kedavra" A blast of green light shoots towards Cedric.

'NO!' Harriet thought as she quickly got up from the ground. She ignored the pain in her head and scar, she rushed over to Cedric and pushed him out of the way of the Killing Curse and she was hit by it instead.

Harriet smiled at Cedric before she fell to the ground, dead.

Tsuna gasped as she shot up in her bed when she woke up from her nightmare/memory. She was panting as she pulled her knees to her chest and placed her head on her knees before she started crying.

Byakuran frowned, he didn't like seeing Tsuna like this. He gently wrapped his Sky Flames around her as he also wrapped his arms around her. He was trying to comfort her. Unknown to them when he wrapped his Sky Flames around her, his Sky Flames unsealed the rest of the seal over her Sky Flames.

Tsuna's Sky Flames burst from her for a few minutes before going back inside her. Byakuran knew what had just happened, since he knew that Tsuna's parallel selves were always sealed when they were 5 years old by Timoteo, the Vongola Ninth and Iemitsu. He was pissed that his Tsuna was sealed like all of her parallel selves.

A few minutes later Tsuna is finally calmed down from the nightmare/memory that she had just had. She is now leaning back against Byakuran, who was running a hand threw her hair.

"What was your nightmare about?" Byakuran asked as he continued to run his hand threw her hair.

Tsuna then told Byakuran that she remembered her past life when she was 5 years old, that she was Harriet Potter in a past life and that the nightmare she had just now was the memory of her dying saving a friend from being killed.

Byakuran was shocked for a few minutes before he got over it. He didn't ask her anything about her past life because he could tell she didn't want to talk about it.

Tsuna finally knows about the Mafia. Byakuran unsealed the rest of the Sky Seal over Tsuna and found out that she has a past life.

Please review, because they are amazing and I need them to help me update my stories.
