AN: Hello people. It's been a while. I present to you the sixth chapter of my story. You guys already know the name so I ain't gonna bother. To those who have been waiting for the update here you go.

"English"

"Italian"

"Japanese"

Make sure you guys read the AN below. It's kinda important. Now without further adieu. Enjoy.

Oh yeah one more thing. Except for a few things here and there I own absolutely nothing in this story. Just saying.

Before that though, I got a question, do you want me to make a complete character profile of Tsuna? You know like Name, DOB, skills etc. Tell me what you think.

Chapter 6

"Ciaossu." A high-pitched voice sounded at the table where Athena and Tsuna were eating their ice cream. There were two reactions.

Athena was a bit startled and started looking for the voice. She didn't know whether this voice was a good thing or bad thing as she looked at Tsuna's face.

Tsuna on the other hand was absolutely still. His eyes started darting everywhere. He also started sweating bullets and trembling. His eyes finally found the perpetrator, Reborn, sitting innocently on the table with a small tub of ice cream in his hands.

"Well well, Tsuna. You didn't tell me you were going out on a date." Reborn said with a very evil smirk. That smirk always sent shivers down Tsuna's spine.

"Does this look like a date to you, Reborn?" Tsuna asked. "I am merely treating a new friend to ice cream. How is that a date?"

"Really? Guess I'll take your word for it." Reborn said. For some reason, Tsuna started to feel really suspicious.

"Where's everyone else?" Tsuna asked.

"On their way."

"Well, might as well do the introductions. Reborn, this is Ms. Athena Black. Ms. Black, this is Reborn, my godfather." Tsuna said.

"Hello."

"Ciaossu." Reborn said while tipping his fedora towards Athena. "Looks like Baka-mitsu and the rest of the posse have arrived." Reborn said while giving a nod to the group that was approaching them.

"Where's Xanxus?"

"Ah… he has gone back to the hotel. He said he'll go crazy if he has to be in this ridiculous amusement park any longer." Daniela replied.

"So did you get everything on your list?" Iemitsu asked his son. "And who's this?"

"Si. Got everything." Tsuna said. "This is Ms. Athena Black. A friend I made today. Ms. Black, this is my father, Iemitsu Sawada and my great grandaunt, Daniela di Vongola, the Vongola Ottavo." Tsuna introduced.

"It is a pleasure to meet you Lord Sawada and Donna Vongola Ottavo." Athena said formally by giving a small bow and curtsy.

"Well… Lord Sawada is my father, Ietsuna Sawada, not me. Ha-ha. Actually I did ask dad to make Tsuna is heir. So please just call me Iemitsu, Ms. Black." Iemitsu said.

"Same hear. I'm no longer the Donna, thank God, the paperwork was horrible. Just call me Daniela or Ottavo." Daniela said.

"Alright then." Athena conceded. "However, Mrs. Daniela, may I ask you a question? Please forgive me if I'm being too impetuous."

"Sure. What would that be?"

"During World War 2, did you battle against someone called 'The Black Serpent'?"

"'The Black Serpent?' now that's a name I haven't heard in ages." Daniela said while taking a seat on the table where her great grandnephew was sitting in. "Before answering your question, boys get out of here. Yes, that includes you too Iemitsu. If Ms. Black here allows, then only Tsuna and Reborn can stay here."

"May I ask why?" Tsuna asked.

"Because, I'm Daniela di Vongola and I can do whatever the damn hell I want. Other than Akira-san, no one, not even the author of this ridiculous story can stop me from doing anything." Daniela replied before saying, "Problem?"

"None whatsoever." Tsuna replied. "And I will shut up now."

"Good. Now, to answer you question. Yes I did. 'The Black Serpent' was one of Grindelwald's top generals. While Hitler's forces conducted the Blitzkrieg in Western Europe, she was the one responsible for the magical Blitz. She slaughtered every French, Belgian and Dutch wizard and witch she and her army came across. While it took 46 days for the non-magical forces. Within 1 month, the Black Serpent managed to topple the French, Belgian and Dutch Ministries of Magic and got them under Grindelwald's banner. There was always a reason why she was rightly feared during the war.

Even before I met her, I knew she would be worthy adversary. Therefore, when I received reports that she was going to launch an invasion of Italy, I decided to act.

What followed was nothing short of spectacular. It was perhaps the most exhilarating battle I had ever fought. My guardians, and me, a team of 7 and various other allied Famiglias had managed to slaughter most of her forces. She however, had singlehandedly killed the 8th Cavallone Boss, managed to leave the 8th Shimon Boss with a nasty scar on his face, she also heavily injured Michael Corleone, the 2nd Corleone Boss and was responsible for many more injuries, fatalities and deaths.

Finally it was just she and I. I ordered my guardians to retreat and recuperate. She managed to push me past my limits. She was the best opponent I had ever faced." Daniela finished after narrated her story.

"But you still won?" Athena asked. "You also left a nasty burned scar on the side of her stomach."

"The scar was because her skill was so good, that I had to use one of my best trump cards against her. Till date, The Black Serpent or should I say, Cassiopeia Black, is the only person who forced me to use that trump card." Daniela replied. "Then again, the reason you asked me this is because you are related to her, aren't you? Not because you share the same family name. But because it the relationship between the two of you is much closer and deeper, isn't it?" Daniela asked.

"I see, no wonder, she praises your strength and intellect. She always says the same thing about you." Athena said. Knowing it would not be of any use to hide anything from the infamous former Vongola Donna.

"You are right. I am related to her. Cassiopeia Black is my mother. She married a Greek pureblood after the war. Mostly because of her reputation as a 'dark witch' no one in Britain would marry her. It was during her travels to Greece, that she met and married the man who would become my father.

The reason I asked you those questions is because, the fact that mother fell pregnant and delivered me successfully can only be seen as a miracle. Unlike Lord Charlus Potter and his wife Aunt Dorea, the reason mother couldn't conceive was because of that scar. It was only luck and perhaps God's grace that she became pregnant. Apparently, mother had lost all hope. That's why instead of naming me after a constellation, my parents named me after the Goddess Athena." Athena explained.

"I see. And how are your parents right now?" Daniela asked.

"Father died eight years ago. He was a Potions Master and he was killed when one of his experiments went wrong and exploded. He was buried in the island he was born in, Mykonos." Athena said with a somber expression. "After his death, Uncle Arcturus, the current head of the Black Family welcomed us with open arms. Mother decided to have me and her use her maiden name."

"You have my condolences." Daniela said. Tsuna and Reborn were nodding along in the background.

"Wasn't Mykonos the same place where the 'Shootout at Mykonos' took place?" Tsuna asked.

"Shouldn't it be obvious? And how does it matter?" Reborn asked back.

"Well, it was eight years ago. And it was quite bloody and brutal. The High Commission was quite pissed off about that." Tsuna replied.

"So that's what it is called…" Athena said softly. However, what she said didn't go unheard by the three Mafiosi. Each and every one of them were surprised by this random piece information.

"Whoa! Whoa! Whoa! What do you mean by 'that's what it is called'?" Tsuna asked the question that was going through everyone's head.

"No, nothing. Guess I spoke too much." Athena said deflecting the topic.

"If the girl doesn't want to answer then she doesn't answer. Don't force her Tsuna." Daniela said. "I believe it is getting late for you Ms. Black. Your mother will be worried about you. Us and Tsuna will escort you to the floo point of the Leaky Cauldron."

"I wouldn't want to be a bother, Mrs. Daniela." Athena said.

"Nonsense. There's no need for such formalities, you are Tsuna's friend and the daughter of perhaps one of the strongest woman I have ever faced. The least I can do is make sure that you get home safely." Daniela said with a kind smile.

"Very well. I shall be in your care then."

"Good."

It didn't take long for the group to reach the floo point in the Leaky Cauldron. Once there, Reborn and Daniela kicked Tsuna on his butt to, "be a proper gentleman and escort the lady." Of course, Tsuna obeyed (what other choice did he have).

"So… I'll see you later then, I guess?" Athena asked.

"Oh you'll be seeing me a lot sooner than you think, Ms. Black." Tsuna replied with a grin.

"Really? How so?" Athena asked curiously.

"Secret. Ni-shi-shi." Tsuna replied with a cheeky grin while bringing his two index fingers in an 'X'.

"By the way, Tsuna. You are permitted to call me Athena. I know that the entire time you have been observing proper etiquette by calling me with my family name. You have my permission to address me by my first name from now on." Athena said while taking a handful of floo powder from the pot Tsuna was holding in front of her.

"Ah crap! Busted! And here I was trying to be a good guy!" Tsuna said with faux panic.

"Are you not a good guy?" Athena asked with an amused raised eyebrow.

"To some. But to many clowns and idiots out there, I am the worst bastard to be alive. Considering the long line of fools always trying to clap me." Tsuna replied.

"Clap?"

"Sorry, it means 'kill' me."

"Looks like you have some dangerous enemies." Athena commented.

"Athena dear. You have no idea. I am a dangerous man, with some money in my pocket."

"Oh well, I guess I will see you later then." Athena said

"Yep. Ciao Ciao Athena. Be safe. Make sure to look left and right when crossing the road. And always cross the road when the signal is green. And remember don't take candies from strangers and shady adults." Tsuna said with a bright smile and waved.

"Of course, Mother." Athena said while rolling her eyes in amusement, before disappearing in a burst of green flames after shouting, "GRIMMAULD PLACE!"

Grimmauld Place, London

The fireplace in Grimmauld Place flared green, signifying the arrival of someone registered within the wards of the ancestral home of the Most Ancient and Most Noble House of Black. Athena Black stepped out of the fireplace to be greeted with half the family in the living room.

The people in the room currently present in the room were Arcturus Black, the current head of the family. Besides him, was his wife, Melania Black neé Macmillan, the current Lady Black. Sitting on another table were Athena's uncle Orion Black and his wife, Walburga Black. Walburga Black was also, Athena's favorite Aunt (no really, she was). After that, were the three sisters: Andromeda, Bellatrix and Narcissa. Even Regulus was sitting with them. Lastly, was Athena's mother Cassiopeia Black, pacing around the room worriedly and shooting glances at the fireplace.

'Uh-oh. Not good.' Athena thought.

"Where have you been?" Cassiopeia Black asked her daughter exasperatedly while enveloping her in a tight hug. "Do you know how worried I was? How long does buying supplementary school supplies take? I was about to send a search party for you."

"Cassi, calm down. Athena's back so let her breath first." Arcturus told his elder sister. He completely understood the panic his sister might have been going through. Even he was worried about his favorite niece.

"Kreacher!" A loud crack.

"Kreacher is summoned by Lord Black?"

"Get Athena a glass of water. After that bring everyone some tea and cakes. It's about tea time anyway." Lord Black ordered the house-elf.

"As Lord Black wishes." Another loud crack.

"Have a seat, Athena." Arcturus told his niece with a warm smile. "And honestly, where were you? We really were worried."

"I apologize for making everyone worry. I was held up." Athena replied.

"Sis, what happened?" Narcissa asked. "Great-Aunt Cassi was about to send of a search party of Aurors to find you."

"Nothing happened. I was just reading through a few academic articles and lost track of time." Athena said.

"Really?" Melania asked her niece with a fond smile. "Those strawberry ice-cream smudges around the corner of your mouth tell me a different story."

The reply to that question was a flustered girl quickly wiping off the smudges with a small napkin.

"Was it a boy?" Cassiopeia asked her daughter in full seriousness.

"Well… I did meet a guy…" Athena replied, not looking her mother in the eyes.

"Name. Address and Blood status." Cassiopeia demanded.

"Can I ask why?"

"He has some nerve asked my girl out on a date. Hell will freeze over before that happens. So will his organs needed for reproduction." Cassi replied darkly.

"He just treated me for being his friend." Athena said. Looking at everyone's disbelieving expressions she proposed a solution, "Look, how about this? Uncle Arcturus, can you please bring out your pensieve? I'll simply show it to you."

After a few moments of contemplation, Arcturus nodded and summoned his pensieve. After that, Athena pointed her wand towards her temple and pulled out a silver strand, which she put in the pensieve. "Go on. Look at it." She told her family.

Everyone in the room, except Athena, dived their heads into the pensieve to see the memory, while Athena was simply enjoying her cakes and tea.

After ten minutes, everyone resurfaced. Of course as Athena expected, her mother put her hand on the place where her scar was to soothe it. What surprised her was Uncle Arcturus doing the same thing to his scar on his upper body.

"Forgive me, if I acted a bit rashly, Athena." Cassi told her daughter.

"Oh I completely get it. We wouldn't want the second act of the Academy Award winning movie, 'The Rebellion of Sirius Black' now, would we?" Athena replied in a deadpan, while secretly enjoying the flinches a few people had shown.

"Right. Yeah."

"So, am I going to get any verdict on my new friend?" Athena asked after a while of silence.

"He looks like a good child." Orion Black said. "Perhaps you should continue your association with him."

"Hmph. That boy better not have any Gryffindor-ish tendencies." Walburga Black said. "Other than that I approve of him. It's not everyday you meet the Heir of the Great Noble Family of Sawada."

"I think he was sweet." Melania said. "He treated you with respect the entire time and never once tried to invade your personal space. He was talking to you as an equal. Not as a man who was expecting you to simply nod to everything he would say just because you are a woman. I have to say, he sure had a really cute smile and sense of humor."

"There was more to that." Arcturus said. "It might have been just a memory, but those eyes… I would recognize those sunset amber eyes anywhere. The last time I met someone who had those eyes, I came out with a scar on my upper body. The scar, which extends from my left shoulder to my right hip. The only thing I could take from him was his right eye."

"I'm assuming you know about this boy then?" Cassi asked her brother.

"I have a clue. But we shall discuss this during dinner. Right now, I still have a pile of paperwork to go through. Tch. How annoying." Arcturus said while getting up from his chair.

"What did you think of that toddler? The one with the yellow pacifier on his neck?" Bellatrix asked her grandfather, with Andromeda and Narcissa nodding in the background, before he left the room.

"If he is who I think he is… Then Diagon Alley, today, was narrowly spared from a horrifying bloodbath." Arcturus replied while leaving the room.

It was only a few minutes later Cassi understood what he meant.

"My word, one of the 'Il Prescelti Sette'. And if memory serves me right, he is said to be the strongest of them all. Reborn, the Sun Arcobaleno and The World's Greatest Hitman/Hitwizard." Turning towards her daughter she said, "Athena, you just became friends with the godson of one of the most dangerous person in the Criminal Underworld."

"Did I do something wrong?" Athena asked nervously. Even she knew that the toddler was not normal. What surprised her was her mother and uncle's reaction. They were shaken. Something that Athena never saw before in them.

"No dear. You did nothing wrong. Rather, it was absolutely brilliant." Cassi told her daughter. "Now go to your room and start packing for September 1st."

"Of course."

"Well I gotta say Tsuna. You sure know how to work fast, don't you?" Daniela told her great-grand nephew with a mischievous smile, while in the car which was going towards the Lanesborough Hotel in Knightsbridge.

"What are you talking about?" Tsuna asked. He didn't like where this conversation was going.

"No need to play coy. We all understood that you were trying to court Ms. Black. Considering she's from a very old and respected family, even if she's British. None of the elders of the Sawada, Vongola or the Yotsuba Families will be able to say anything. Well played Tsuna, well played." Daniela said, the smile still present.

"I was not trying to court her!" Tsuna replied. "We simply found out that we have the same interests."

"Really? Because Mama is quite ecstatic at the fact that you found a girl." Reborn replied. "Ms. Black has Mama's full approval."

"OOOOOOOOOIIIIIIIIIIIII! What the hell did y'all do?!" Tsuna asked with his eyes bulging comically.

"Check your phone." Reborn simply said.

Tsuna did so and saw that he suddenly he had a ton of messages. He opened one and started reading it. As he went through each and every one of them, he started to go paler and paler.

"GODAMMIT REBORN! WHAT THE HELL DID YOU DO THIS TIME?!"

"I did my, shall I say, civic duty. That is to inform Mama of any… interesting developments." Reborn calmly said. His smirk firmly in place. He loved it when he saw his godson squirm.

"SOME GODDAMN CIVIC DUTY! HALF OF MAGICAL JAPAN THINKS I'M DATING NOW!"

"You're not?" Iemitsu asked with faux surprise.

"Don't start, dad. Cause-" Whatever Tsuna was about to say was cut off as his phone started to ring. The moment Tsuna looked at the caller ID, he cringed. It said 'Mom' and there was a picture of Nana Sawada and Tsuna dressed in traditional Japanese attire, during the festival of Hanami.

"H-Hello?" Tsuna asked nervously.

"Kyaaaahhhh! Tsu-kun, congratulations! I am so happy and proud of you. You finally found a girl! Do bring her to Japan to introduce her to me. Oh, I'm over the moon. My son is growing up. Even your oba-ue, extends her complements. She has my full approval. Even your grandparents on both sides approve of her. Oh, I'll talk to you later. I have a meeting to attend. Tell me all the details later on, OK? Ja ne. Oh, Honey, I love you. That was for Iemitsu if he's with you." Nana Sawada, the wife of Iemitsu Sawada and daughter-in-law to Ietsuna Sawada and his wife, Aguri Sawada neé Kuchiki, said happily over the phone.

The entire time, Tsuna was saying things like, "No, wait", "Hang on", "Um, can you please listen". He took the phone of his ear when the tone sounded, signifying his mother had put down the phone.

"Well… She's happy." Tsuna said.

"Told you." Daniela and Reborn said together with grins. Iemitsu was trying hard not to go on a full-blown laughter quest. Tsuna didn't even bother to look at them. He was just trying to reduce the headache.

Lanesborough Hotel, Knightsbridge, London.

After half-an-hour, the car pulled in to the Lanesborough Hotel's Entrance. As they made their way inside, they saw Xanxus sitting on one of the couches with a manila folder. When he saw the group he went towards them and handed over the folder to Tsuna.

The moment Tsuna saw the three seals on the cover of the folder, he had to take in a sharp breath. "Goddamn, the seals of the 'Unholy Trinity.'"

The three seals were in a triangle form. One seal was at the top, while the other two were below it and side-by-side. The top seal was the seal of The President of the United States of America. The other two seals were of the US Joint Chiefs of Staff (JCS) and the seal of the Secretary of Magic aka the seal of the President of the Magical Congress of the United States of America (MACUSA).

"Where did you get this from again?" Tsuna asked Xanxus as they were in the lift, heading towards the Presidential Suite.

"VARIA Code breakers intercepted this transmission from the Pentagon to the White House and the Woolworth Building, New York. The Shitty Shark was there so he told them to flag it. The entire transcript is in the folder." Xanxus replied.

"One more thing, a jet took off from Andrews Air Force Base, one and a half hours ago. The geeks tracked its destination." Xanxus added.

"And it is?"

"London Heathrow."

"Oh Fuck. Any ID on the passenger or passengers?" Tsuna asked.

"Passengers. The photos are in the folder. We managed to hack in to the cameras over there." Xanxus replied. They reached the Suite and went in, where Tsuna took a seat behind a desk to properly go through the folder. Xanxus, Daniela, Reborn and Iemitsu took seats in front of him.

Tsuna did not like this. He did not like this one bit. If they are being sent it could not be good. "The Americans are serious. If these three are being sent. It wouldn't take a genius to figure out why they have been sent. Sadly, the British magicals are not so smart."

The people in the pictures were as follows:

The first person in the picture was a female who was in her mid-20s. She had short black hair with a petite body. She was dressed in a businesswoman's suit.

The second person was a well-built male in his early 40s. He was wearing a standard suit. His black hair was slicked back with a small part falling on his forehead. His eyes were hard, exactly what one would expect from a military officer.

It was the third person in the photo that had Tsuna nervous and feeling like he wanted to bash his head on the table. They just had to send that one person whose skill in espionage and information gathering is really bad. She was a very beautiful girl who was the same age as Tsuna. She had blonde hair and blue eyes. Ribbons tied her two wavy tresses. Every time he saw her, Tsuna would always remember this girl's rivalry with Hinagiku Katsura, the former President of the Mahoutokoro Student Council and his cousin sister, Miyuki Shiba, the former Vice-President of the same committee, during the Survivor Series event, which was held two months ago in Japan. An event he himself had taken part in.

The names of these people were as follows. The first woman was Warrant Officer Sylvia 'Sylvie' Mercury First. The man was Major Benjamin 'Ben' Canopus. Lastly, the blonde girl was Major Angelina Kudou Shields or as her well known alias Major Angie Sirius. All three of these individuals were part of the same military arm that specialized in Magic and reported directly to the US JCS. The name of this organization was STARS.

"They just had to send their best on this one didn't they?" Xanxus asked rhetorically.

"Probably has something to do with how this community's idiotic Minister of Magic, Millicent Bagnold's public humiliation of the Americans offer for help with the terrorists." Daniela said.

"Yeah. She said that nothing was going on and everything was fine and dandy." Iemitsu said.

"Something tells me, she and Crouch are in the pockets of almost every one of these terrorist who is rich." Reborn said.

"And the Americans have obviously sent those three to 'observe' and take action accordingly. Same as me." Tsuna said.

"I'm assuming you have a plan?" Reborn asked, recognizing that his student is becoming the cold and calculating person who always makes one of the best plans and tactics with the most minimal losses.

"I do." Tsuna replied. "First of all, Reborn inform Nono about this. Also ask him to have a few words with the US President."

"Why?"

"You'll see." Tsuna replied. "Next, Xanxus. Tell Squalo to send a copy of this folder to the Ninth, Grandpa and Aunt Maya. They have to be informed about this development.

Aunt Daniela, can you please check with MI5 and MI6, if any of their agents are assisting them in this operation?"

"Why involve the MI's into this?" Daniela asked.

"Because even if they have come here covertly, that jet will be immediately tracked, the moment it enters British Airspace. Also, they are not stupid enough to make Lina go into hostile territory alone. She's too important for them. Hostile territory in this case being Hogwarts or any other British magical area. Therefore, MI5 or MI6 will probably station someone in Hogsmeade Village, where she can be immediately extracted if things go south. Sylvia and Ben will probably be running the show from the American Consulate in Edinburgh, as that place is the closest to Hogwarts. Magical USA and Britain are not friends, that doesn't mean non-magical USA and Britain are also not friends. NATO tells me a different story. I hope that is enough of an explanation." Tsuna explained.

"It is. Who do you want me to call?" Daniela asked.

"Talk directly to the heads of both the organizations." Tsuna replied.

"And what are you going to do?" Xanxus asked.

"First, I'm going to sleep off my jet-lag. Then tomorrow, I'll go the swimming pool, the spa and the Jacuzzi. Day after tomorrow, I'll have a word with our friends who are currently inbound at the US Embassy here in London." Tsuna replied.

"What makes you think they'll be at the embassy?" Iemitsu asked.

"Oh they will be. At least till September 1st." Tsuna replied.

"Well then, looks like we finally have a plan of action." Reborn said. "How about we all disperse for now and meet for dinner downstairs?"

"Yeah, seems like a good plan." Daniela replied.

After that everyone left for their bedrooms for some R&R.

AN: So there you have it folks, the sixth chapter. I also have to say something. I am going to be slow in the update of chapters because I am in Uni and I have a few essays to write. Therefore, I may or may not work on the next chapter for a while. It honestly depends. That does not mean I am putting this story on hold or anything. Expect quicker uploads during perhaps Christmas or something, as I will be a bit free then. I thank each and every one of my readers for their patience with me. It really means a lot. Also, I am planning to have Tsuna answer questions from you readers. So if you want Tsuna to answer any questions, please PM it to me and I will forward it to Tsuna. Lastly, do you guys want to know about the messages that were in Tsuna's phone? Write your answer in the comments. Also yeah, Reborn is scary enough to even shake powerhouses like Arcturus Black and Cassiopeia Black. This is MKOFFICIAL357, signing out.
