~*-.-*~

As the rescue party entered the building, they immediately encountered a mess. They tried to find a way to the next floor but so far have only found destroyed stairs and no working elevator.

Daphne had slid up her ice mask again and Harry just acted like he normally would with Tsuna and Reborn.

As Gokudera and Tsuna were getting frustrated, Reborn finally told them, "Mukuro will most likely be on the upper floors. This means that there should be a flight of working stairs somewhere." Seeing their confused faces, he elaborated, "It's easier to defend if he narrowed down the possible attack paths. However, this strategy also cuts the escape routes that he has. He must be very confident..."

They continued to search and finally found the way up: an emergency ladder. However, as they walked closer, a yo-yo blocked their path. They followed the line of the weapon to see Chikusa. As he moved to attack, several sticks of dynamite were thrown at him. The dynamite exploded to form a smoke screen.

"Jyuudiame, please let me deal with him. Go ahead."

Bianchi tried to convince her brother to change his mind, "Hayato, the virus cure that Shamal gave you still needs time to complete its job. You'll suffer those painful attacks again..."

Gokudera started at her, "But for what reason am I here then?" he asked.

"Hayato..." seeing that he was serious she turned back to the direction of the ladder, "Come on, let's go."

The bomber added, "Please go ahead boss. Once this is over, we'll have some fun together." He grinned.

Tsuna made up his mind. "Of course, " he said, firmly. He too ran to the ladder.

Harry and Daphne just waltzed across the room. Harry whispered to Daphne, "We'll be meeting Mukuro soon. Can you follow the plan that I told you on the car? Or at least try to..."

Daphne replied equally softly, "Fine, but I want a spar with you later, and I get to chose the rules."

Harry agreed.

As they left, the witch and wizard heard Gokudera telling his opponent, "You were pretty easy in letting them go."

Chikusa replied, "Those were Mukuro-sama's orders." He then muttered to himself, "though I still don't know about his so-called friend..."

~*-.-*~

Harry and Daphne lingered in the back as Tsuna and Bianchi led the way around the second floor. Reborn was on Bianchi's shoulder.

Finally Tsuna decided to comment, "I don't think that Mukuro is on this floor. Let's go on to the third floor."

As they proceeded up another flight of stairs, into the cinema area, they were met with to sight of a blue-indigo haired teen sitting on a couch who said, "I'm very happy that we could meet again."

Tsuna recognized the mysterious figure as the same person who he had encountered in the forest. "It's you! So this was where you were being held?" He turned back to the others to explain, "I met this person in the forest. He's a Kokuyo student and a hostage."

The mentioned teen said, "please come forward slowly. I would like to get to know you better, Vongola Decimo."

Harry murmured, not noticed by the rest of the occupants, "Now Daphne."

"Eh? Come did you know that?" asked Tsuna.

Bianchi threw a platter of poison cooking at the teen. Realization dawning her face, "You're mistaken, that's-"

"I'm the real Rokudou Mukuro" The teen finished her sentence.

"Wha?" Tsuna was surprised.

As they were discussing this, Daphne and Harry quickly moved to the side of the room, the opposite direction of where Tsuna, Bianchi, and Reborn had discovered the presence of Fuuta.

Their movement caught Mukuro's attention. The illusionist mentally asked

:Harry? Mind explaining to me what you are doing?:

-Sorry. You'll have to figure out with everyone else to make this very convincing...even if you are a good actor. But I'll tell you this, you will have to get captured again...-

:...:

-Sorry...-

They both turned back to the fight as Fuuta stabbed Bianchi with a trident.

Tsuna cried, "Bianchi! Fuuta, what are you doing?"

~*-.-*~

Meanwhile, Gokuedera and Chikusa were fighting all out.

When Gokudera pulled the same trick that he did last time they fought, Chikusa quickly got rid of all the dynamite in the air. However, because he was focused on those, he did not notice sticks of dynamite at his feet, injuring him.

However, at this time, Gokudera's wounds started hurting again. Again? Why do they always seem to hurt at the worse times? he thought.

As he leaned against a window, he didn't notice Ken on the other side. The feral teen's claws smashed the window and attacked his unsuspecting victim's chest. Gokudera clutched his new wound before swaying a few times. He finally fell down a nearby flight of stairs, too weak to move his body. The silver-haired teen couldn't move his body. Frustrated, he noticed one of Birds's birds perched on the wall near his head. It started singing, "The green trail of Namimori. It's not big, nor small. Nami is great~"

Gokudera realized something and started to laugh. He threw the dynamite in his hand backwards to the wall where the bird was.

Ken taunted, "Ha, What were you aiming for?" thinking that Gokudera was trying to aim for the Kokuyo students and was too weak. So he was surprised when Gokudera talked, "The only person would would love our lame school anthem has to be you..."

The smoke cleared to reveal

"...Hibari Kyouya"

The prefect, already expecting that Gokudera would release him, just stood up and stated, "I could have gotten out on my own, but never mind..." and he really could if Hibari had removed the seal on his Masked tattoo. He continued, "Shall I take care of these two herbivores?"

Gokudera just replied, "That's what I'm counting on you to do"

Ken and Chikusa just looked to see a yellow bird on his shoulder, "That guy,he tamed Birds's bird..."

Hearing what the two in front of him were discussing, Ken snorted with derisively, "What's this half dead guy talking about? I'll handle him. Lion Channel"

Hibari raised an eyebrow before kicking up his tonfas that were on the floor, "Oh, are you first?"

Ken just charged, annoyed at the taunts. However, none of the attacks seemed to have gotten to Hibari who had dodged every single one of them with ease before slamming his tonfa into Ken's face, causing him to fly up the stairs and out the window.

"Ken!" Chikusa was worried for his comrade but couldn't go to him for Hibair had set his sights on the needle user next.

~*-.-*~

Daphne and Harry watched silently as Fuuta stabbed Bianchi and proceeded to attack Tsuna. Reborn stated, "He's been possessed," though it was really only for Tsuna's benefit.

Daphne studied Fuuta and Mukuro, trying to find out how to copy to technique and was similar to an Imperio. The only thing she found strange was that the escapee's right eye was red and with a six on it. She shrugged. The Slytherin figured that she would ask when the convicts were in court again and, if he was like many other fighters, explained during the battle.

Fuuta was getting closer and closer to stabbing Tsuna when Harry pulled Tsuna to the side and blocked the trident with his hands.

"Harry? Thanks. I thought I was a goner on that swing." Tsuna started rambling. He did not notice that after Harry stopped Fuuta, he had carried the boy back to where he was standing earlier. He then put a yellow-ish white piece of paper with strange scribbles on it onto Fuuta's forehead. The Ranking Prince then collapsed in his arms. Mukuro also grunted in pain after a part of him was forced out of Fuuta.

When Tsuna looked questionably at Harry, the wizard just shrugged and said, "Sorry, but I cannot help you in this, at least not really. You are on your own."

Tsuna looked confused. "Harry?"

This time Daphne answered. "As members of the Evan famiglia, we should only approach combat if necessary" "though not everyone is like that" Daphne ignored Harry and continued, "Also, the duty of the Evan famiglia is to decide if a mafia member violated the law. If he has, then also the sentence. Our purpose for being here today was actually to see if Mukuro did indeed violate any laws and see beforehand what might be a good punishment."

Tsuna looked in shock. "Then...you weren't really here to help? Harry?" he asked desperately, hoping for his neighbor to deny what Daphne had said.

Harry started straight into Tsuna's eyes and said, "Sorry, though if you were in real trouble, I would help. Oh and aren't you supposed to be fighting Mukuro right now?"

Tsuna was not in the mood to fight, but remembering everyone who had suffered because of the teen in front of him, he took the whip that Reborn had offered and ran for Mukuro. His skills, however, did not match his determination. The weapon missed its target completely, only catching the floor. However, because Tsuna had tried to attack, Mukuro was free to use his powers on the boys with having to seal his tattoo.

The escapee banged his the bottom end of his trident on the ground while creating an illusion. Daphne sensed it because of her Occlumency while Harry felt it from his tattoo. When the floor started to break apart and shift, the wizard and witch just decided to sit, Fuuta in Harry's arms. They watched as Reborn hit Tsuna to stop him from seeing the illusion.

Harry continued to lean on the wall while Daphne perched on one of the large steps to the side of the room, as Mukuro unleashed snakes onto Tsuna. As Mukuro continued taunting Reborn, not seeing Tsuna as a threat, a tonfa came flying toward the illusionist. Everyone turned to see Hibari and Gokudera leaning on each other by the door. Seeing that everyone saw them, Hibari threw the bomber to the side and charged forward to attack the pineapple-haired teen.

"Che. This will only take an instant" Mukuro told everyone. However, the pair fought for a few minutes before Mukuro decided to finally make illusions of sakura, taking advantage of Hibari's disease. Hibari visibly tensed as Mukuro laughed, saying, "Come, kneel before me once more." As Hibari started falling forward, he quickly swung his tonfa into Mukuro.

The illusionist was surprised at the sudden attack when Gokudera explained how he got the antidote for the Sakura-kura diease from Shamal for Hibari. The prefect quickly hit Mukuro a few times before the sakura disappeared, revealing that they were illusions. Hibari continued hitting him before collapsing.

Watching this, Harry sweat-dropped. Wow, Hibari must have been really mad at Mukuro. He wasn't like that even when we sparred in our mind-scape.

Harry knew that Mukuro was not defeated, not yet, but decided that this was getting kind of annoying because he already knew the outcome would be that Mukuro is defeated. The only reason why the illusionist still continued was as a favor from Harry to test the group.

So Harry was not surprised when Mukuro moved on to possess Bianchi. When he saw Mukuro had also possessed Ken and Chiusa with his Sixth Path, he grew alert, hoping that his suspicious was not true. Sadly it was as he felt Mukuro's mind move to try and take over Tsuna's. Harry quickly pulled himself into Tsuna's mind, hoping to stop Mukuro.

Thankfully, Harry and Mukuro entered at the same time, and Harry was able to stop him. "Mukuro! What are you doing?"

Mukuro turned to see a very angry Harry who continued to castigate him, "How else would you ever explain your presence if you can already take over Tsuna?"

Seeing reason in Harry's words (kinda) and mostly because he didn't want to fight a Harry in full power, Mukuro withdrew. Harry also withdrew to see that everyone else Mukuro possessed had been defeated by Gokudera and Tsuna who was hit by the Rebuke Bullet. Now, the only one left was Mukuro himself.

However, Gokudera became too injured to fight so he couldn't fight, nor could Mukuro find any use for a broken body, so it was a one on one Tsuna verses Mukuro.

Mukuro taunted Tsuna. "So your battle sense has improved, I'll give you that. However, you're pushing your luck if you think that was all it would take to defeat me. Out of the six paths, there is still one that I have not used yet."

Reborn stated, "The Fifth Path, Realm of Humans."

"That is correct, this world that we are living in. Among the six paths, it is easily the most dangerous." Seeing Tsuna's look, he defended himself, "I am not being cynical"

Tsuna raised an eyebrow

"Really, I'm not. Because I hate this world, I hate this skill the most. If possible, I would not have used it at all," Mukuro continued. "It is the most dangerous of all paths.

Harry was incredulous. He thought, You don't have to use it...you just want to show off and creep Tsuna out...

Sure enough, Tsuna was slightly, because Mukuro had basically pierced his own eye. The illusionist removed his hand to show a bloody eye with the number five on it and grew an aura of black, fighting spirit.

At this point, Daphne watched with interest. The only skills that needed the user to cause self-harm were usually powerful ones. It seems like Mukuro was not boasting about how the fifth path was the most dangerous. Harry just rolled his eyes at the dramatic speech.

Both the witch and wizard, however, stiffened when they felt Blaise trying to communicate to them through a communication mirror instead of a cell phone, especially since Blaise wasn't supposed to use magic. Seeing that the others were occupied, they discreetly left the room and checked the mirror.

"Blaise" they greeted.

"Hey guys, Yamamoto Takeshi is currently asleep and nobody else is here. I left my cell phone somewhere in the airport so..." Blaise answered their unspoken questions rather sheepishly. "Anyways, I just wanted to say that Draco contacted me through the mirror to say that the Vindice are preparing to leave for your location so you guys better wrap everything up."

After both thanked Blaise, Daphne tucked away the mirror and followed Harry who left earlier to see the Mukuro and Tsuna were still fighting. Seeing that they did not have much time, he moved between the two fighters to stop their attacks. Then he chopped the back of Mukuro's neck with the side of his hand, causing the illusionist to collapse.

When Tsuna looked questioningly ask him, Harry just said, "You'll see..."

Tsuna's flames went out and was left staring at Mukuro's unconscious figure. Suddenly he shouted, "Oh yeah, everyone's wounds!"

Reborn reassured him, "Don't worry, the medical team for Vongola has arrive in the area. Lancia's wounds are being treated right now"

Tsuna sighed in relief, "Thank goodness..."

He moved closer to Mukuro but heard a shout of "Don't touch him!" The trio looked up to see the crawling forms of Chikusa and Ken. "Step away from him, especially you, Potter Harry."

Harry was indifferent as the two explained to Tsuna why they followed Mukuro even though he possessed the two of them.

"This is nothing compared to what we suffered..we were guinea pig for our own family"

Reborn told them, "I thought so, but what you said definitely proved it, you guys are a part of the Estraneo famiglia that created the possessing bullet weren't you?"

Ken scoffed as he slowly tried to rise, "Because of that bullet, we were prosecuted. Whenever we stepped out the door, guns would be pointed at us from other families and we were shot down like bugs. This is caused the adults of the family to experiment even more, to find the ultimate weapon. We all died one by one. No matter where we go, how much we struggle, there was no way for us to live. Then he, all by himself, he destroyed that miserable life. That time, for the first time since birth, there was a place for us to go."

Listening to the speech, Tsuna was moved but he told them, "But I also can't let my friends get hurt, since that's the place for me."

Everyone was quiet until the door slid open and dark figures moved in.

Reborn told them, "The medical team has arrived," but Harry contradicted him, "No, it's not the Vongola medical team, it's the Vindice."

The chain collars that clicked on the necks of the three convicts there proved it. Tsuna followed the chain to see the person holding it.

It was a figure with a bandaged face, like a mummy's. He, or she, had a black top hat and a long bat coat with white ruffles. The Vindice member also wore white gloves. There were two similarly dressed shadows behind the one holding the chain though those two had black gloves instead of white ones.

When Tsuna asked, Reborn started to explain a bit about them "They are the enforcers of the Mafia world."

As the guards dragged the three away, Tsuna tried to stop them, only for Reborn to command him, "Stop Tsuna, don't try. It would be very troublesome to get involved with them. Just leave them alone."

Tsuna asked, "Are they really scary?"

Reborn replied, "Yes, the only family that has contact with them regularly is the Evan famiglia." He nodded toward where Daphne and Harry stood.

"Why?" asked Tsuna, "What will happen to those three?"

This time Harry answered, "The Evan famiglia are the judges of the Mafia world, it would make sense that we would work with the police. And as for the outcome..." He winked at them, ignoring Tsuna's slightly depressed mood, "it's a secret~"

Reborn pitied Tsuna and just told him, "It depends on who takes the case, but it will not be anything light. We do not live in a kind world."

Tsuna didn't say anything as the medical team finally arrived. He then asked them, "What about Lancia-san?"

"He was taken away as well"

"What?"

Tsuna then saw the injured faces of everyone who was hurt, and also remembered Yamamoto who had medical attention elsewhere. "Will they be alright?"

Reborn reassured him, "They'll be fine. Our medical team has top class medics after all."

Tsuna suddenly felt an intense pain, What's this, why does my body hurt so much from muscle pain?"

"The Rebuke Bullet's battle mode abuses the body severely; the burden on the body came back as pain" Reborn answered calmly as Daphne, Harry, and him watch Tsuna rolling on the floor in pain.

Harry whispered, "Way to ruin the moment," to Daphne who just rolled her eyes.

"Let's go" she said. "We need to get them in order for the plan to work.

Harry nodded and told Tsuna, "I'll see you soon." To Reborn, he said, "Yes I'll talk to you later." The wizard then followed the witch out the doors.

Tsuna didn't hear what Harry said as he was in so much pain that he fainted. Reborn also nodded and just plopped down besides Tsuna, asleep the moment he touched the floor.

It was a fine time to relax with the temporary danger taken care of.

~*-.-*~

A week later, Namimori

"Gokudera-kun! Yamamoto-kun! Bianchi! You're all out of the hospital too!" Tsuna cried in relief.

As the group finally reunited after a week of recuperation in the Namimori hospital, Reborn was watching his charge over from a distance. His wide eyes narrow in thought.

Harry Potter. At first, Reborn just thought Potter was just a teen with maybe a parent high-up in the government or something. He already started to have suspicions when Luna Lovegood had turned up but only dismissed it. He thought that perhaps she was the reason for his obscure records. The Evans famiglia would certainly have power to black out something simple as that.

If possible, the hitman had thought to make Potter a new addition to Tsuna's famiglia, nothing more. Maybe not even a guardian. But now... over this incident, the Arcobaleno finally learned something about the mysterious foreigner, only for even more questions to popup. Harry Potter could have been related to Lovegood and that could explain how he knew the others, but the way he subtly controlled Daphne Greengrass and Blaise Zabini spoke otherwise.

When Reborn went to confront the teen at his house the day after the Vindice made their appearance, there was nobody in the house.

In fact, if it wasn't for the fact that Reborn had seen Potter walk into the house with his brother and the fact that there was no dust in the house, the hitman would have thought that it was one of those display homes, complete with fresh food in the refrigerator. Reborn had immediately raced out of the house and toward his charge, only slowing down when Tsuna was in sight and completely safe. He let out a silent sigh in relief. Someone had tripped the simple security system that he had secretly placed in Tsuna's room. It was directly linked to his phone and only sounded when someone not authorized by him entered the room, such as Harry Potter. Looking around, he caught the sight of a blank white envelope sitting innocently on the nearby table.

Opening it, Reborn read:

Tsuna,

Sorry I could not see you before you woke up. There is a situation that I have to deal with, relating to my family and friends back home. I'll probably by back soon, but don't count on it.

Sorry,

Harry Potter

Folding the letter and placing it back into the envelope, Reborn placed the message where he found it. Sitting onto the chair near the bed, he leaned by in contemplation. This definitely was not a coincidence, but Potter should have known that doing this would place a lot of suspicion onto himself...so why did he go at this time? Reborn rubbed his eyes tiredly. "I'm getting too old for this, " he muttered. "But then again, I'm in the body of a toddler..."

He stopped when he sensed that Tsuna was waking up. Leaning forward until the tutor's eyes were right in front his student's, he waited for Tsuna to open his eyes. Refraining from crackling evilly, he thought wickedly, But this job isn't that bad after all...

~*-.-*~

A day later in Vendicare

A hooded figure appeared right in front of a door with a soft pop. Surprised, its guards quickly reached for their weapons only for there hands to drop down when the figure held up a ring. The ring was gold and embedded into the band was a circular piece that contained a picture of a scale and a star and moon, merged, in the background.

Seeing it, one of the guards knocked softly on the door. "Boss," he called. "The Evans famiglia head wants to see you."

A deep voice answered, "Let him in."

The guards bowed to the Evans boss before opening the door for him.

The figure glided in, silent.

Once the door closed, the Vindice boss, seated on the a high chair, its back facing the door asked, "So why are you here?"

"I came to discuss a few recent prisoners you had...Bermuda Van Vichtenstein."

The newly revealed Archobaleno turned around to smile, "Nice to see you too, Harry Potter."
