The house was small and lovely, fitting perfectly against the bright background of the slowly rising sun. Tsuna ran nearly silently towards his house, Harry following along beside him, the others had long since headed home, leaving the two of them to the last stretch to Tsuna's house. Tsuna turned as he heard Harry stop, tilting his head as Harry looked up to a roof behind them where a shadow quickly flitted away. Harry's eyes narrowed but he said nothing. Tsuna shrugged and carried on up the pathway, opening the door with his key and gesturing for Harry to come in. The green eyed boy nodded and slid silently inside the house, following Tsuna up the stairs to his room. However the second Tsuna went to step into the room Harry tensed and pulled him out, throwing his arm to the side and, in a burst of black and red flames, called a weapon, it was the same colour of his flames and had a twin. It's official names were twin hook swords and Harry was very skilled with them. Harry kept Tsuna firmly against the wall with his flames, stretching out one hook sword towards the enemy, a small child holding a gun.

"Tsuna, do you know this kid?" Harry murmured softly, eyes narrowed.

"Yeah, that's Reborn." Tsuna said, smiling at the hitman after Harry released him. In the shadows of the room, Harry couldn't make out the features of Reborn but as Tsuna turned on the light he dropped the hook swords, which disappeared in a shower of sparks. Harry stepped back, eyes wide and staring as he spied the small hitman.

"You. You're.. Riven." Harry said softly. "Granted you're smaller than Riven but.. I'd recognize you anywhere."

"It's nice to see you again, Harry." Once Riven, now Reborn, murmured softly, gently releasing Leon onto his hat. "I had nearly given up hope of finding you again."

"Oh right." Harry scoffed, putting a silencing barrier around the room. "Well you didn't looked very hard. I waited 5 years for you! Five years, Riven! Or is it Reborn now? I met them. The wizards. You always spoke about them and I never believed that they were real but they came looking for me. Trained me and threw me into that war WHICH YOU RAN AWAY FROM." Harry roared. Tsuna looked nervous as he stepped around Harry to perch lightly on his bed.

"I..- I'm sorry Harry. I didn't mean to run, I just! I didn't think." Reborn wasn't acting like his usual self and Tsuna couldn't help but be nervous. When Reborn acted different, things, good or bad, happened and they happened quickly.

"Look, don't worry about it." Harry murmured softly, he turned to Tsuna with calm green eyes, ignoring Reborn for the moment. "You mentioned earlier that you were the Vongola X, yes?" Tsuna nodded slightly in reply. "Well then, if you'll let me, I'd like to join your family."

Tsuna was blown away by this statement, never had someone actually asked to be in his family, circumstances sort of forced them together. Harry went slightly crimson, glancing down to the floor and reaching up to rub the back of his neck, he noticed Tsuna had locked eyes with Reborn and they seemed to have a silence conversation before Tsuna spoke. "Yes, yes of course you can. But.. Do you think you could teach me your way of using flames? It's just, you can do a lot more with your flames and I'm sure it'd be useful."

"I'd be interested to learn too, if I could." Reborn said tentatively, hopping up onto Tsuna's shoulder.

Harry smiled a true smile and nodded. "In the morning I'll teach you one of the more useful tricks, useful for spying and sneaking about in enemy bases. It's called the animagus transformation and it involves bringing out your inner animal. Now, don't be fooled. Your inner animal isn't the animal that looks like you or acts like you. For example, if it was you'd be a lion, Boss. Your inner animal is the animal which most resembles you and can bond the best with your flames."

"Hmmm." Reborn hummed quietly, looking deep in thought before he was suddenly in his night clothes. "Well, I'm going to sleep."

Harry smiled and shifted out of the way, he studied Tsuna for a second before dropping to his knees and pressing his head against the ground. Tsuna jumped when he noticed, about to protest before Harry lifted his head and began to speak. "Tenth, I promise that I will protect you to the best of my ability. I will not let you die for any reason, not even to save my own life."

"Harry! You can't give up your life for mine!" Tsuna protested, though he was blushing lightly.

"I can and I will." Harry said firmly. "Now, good night Boss, I will sleep on the floor." Harry stood and went over to the window, sitting with one leg propped up, his head leaning against the wall. Tsuna stood and studied Harry for a second, noticing that if he was holding a sword against him he'd look like a samurai. He laughed at the thought and went off to get changed, leaving Harry to drifted off in silence. It was only when he came back that he draped a blanket around Harry's body and then got into bed.

Morning dawned sluggishly, the sun creeping over the horizon as Harry awoke, he was silent for a second, relishing his first natural sleep in a while. The mental institution wouldn't allow him to sleep naturally, thinking his nightmares would hurt him or something else as stupid. Harry noticed the blanket around his shoulders and smiled, standing up slowly as he gently folded the blanket, lightly placing it on the floor as he opened the door and crept downstairs where he heard the movement in the kitchen from Tsuna's mother. Harry opened the door quietly, blinking owlishly as the woman just smiled at him.

"Hello there, a new member of our little band of misfits?" She said softly, smiling that mothers smile that eased any worries he had. When Harry tilted his head questioningly, she pointed at the two sleeping children, one was a young black haired boy and wearing a cow outfit and the other, also black haired, was a girl wearing a Chinese outfit. On the table across from them a tall woman with reddish-brown hair drank some steaming tea and standing curiously in front of Harry was a boy with blonde hair who smiled brightly and pulled him into the room.

Harry ruffled his hair and bowed at the woman who was his boss' mother, he straightened and smiled. "It's an honour to meet you ma'am. My name is Harry Potter, or Potter Harry, as it would be here."

"Such manners." The woman said softly, a gentle smile on her lips as she dried her hands and came over to him, wrapping him in her warm motherly embrace, such an embrace that Harry froze in shock before relaxing. Harry had never felt that kind of hug , Mrs Weasley had her moments but they weren't true hugs, like this one. "Welcome to the family, young Harry." Nana murmured softly, pulling back and stroking his cheek lightly. The moment was broken as she bustled off, swiftly producing a plate of eggs and bacon and setting him in a place next to the sleeping girl, who woke, her eyes blinking drowsily.

The black haired girl looked at him with surprisingly untrusting eyes before nodding and leaping onto his shoulder and smiling. "Hi! I'm I-pin, it's nice to meet you.."

"Harry." The black haired man confirmed. "and who are your friends?"

"Bianchi." The woman affirmed, nodding slightly.

"That's Fuuta" She murmured, pointing at the blonde who smiled in greeting. "And this is Lambo!" The girl introduced cheerfully. The young boy woke at his name, bursting into tears for no apparent reason. Harry frowned slightly and leaned over, picking up the tired young boy and gently setting him onto one of his shoulders.

"Well, Lambo, Nana, Fuuta, Bianchi and I-pin, of course, it's an honour to met you all. I'm Harry." Harry said, looking up at the now calm young boy on his shoulder. Lambo leapt down into his arms and hugged him lightly before falling asleep again, his thumb resting quietly in his mouth. This was the scene that Tsuna walked in on, blinking in shock for a few seconds before going to sit down with Reborn beside him.
