Its a peaceful day. Sawada Tsunayoshi is now signing all of his paperworks with his unbelieveable speed.
"Shit, this paperworks is endless!"he muttered. Suddenly,his pen is out of ink and he stop. "This is the hundredth pen ...,"he throw that useless pen to a cardboard beside him. There was so many pens with no ink there.
'Hmm maybe a little rest will not make Reborn angry' thought Tsuna. He open his drawer and looking something interesting. Because every time his guardians gave him some suspicious thing from mission ( Why he kept it on drawer if that was suspicious??),he always threw it to the drawer.
Tsuna stare at a hourglass shaped pendant he was holding. He confused, who is the person whose taste is really bad to make a pendant with a hourglass shape ?. "Maybe something will happen if I turn it ,"he said as he turned the pendant upside down.
Instantaneously the atmosphere around him changed. It's the same when he went to the future ten years ago. "What the hell is happen here???"he said. "Uurgh,Reborn would have been angry if he knew I was doing this carelessly ".
A minute later, he standing in his old room . Still confused, he stare at that room. And he was so surprised when he see the calendar there. "Dont say i'm going back to the past..."he sit on his old bedroom, still dont believe the truth. 'How it can be?, i know there was ten year bazooka who can bring person to future,but i never heard there was a thing that can do opposite thing!'he thought.
Then,he heard some footsteps on the stairs. 'Ok...keep calm, Sawada Tsunayoshi, this will be awkward'he take a deep breath. A few minutes later, the door opened, and sure enough, the person who opened it was none other than himself in the past.
" HHHIIIIEEEEEE!!!".
Tsuna (past) POV
'Uurghh,i get a headache... damn that hyper intuition' i thought while climbing stairs into my bedroom. 'Is there something bad happen?,nope...this is a peaceful day'.
I open the door,but when i opened it, i was so suprised. There was an adult, he looks like me, wear a clothes like Primo, and staring at me.
"HHHIIIIEEEEEE!!"i cried.
I fell and stay away from the door. That could be an intruder, because if my future self come here, i shouldn't be here. I take my gloves and my pills and prepare to enter Hyper Mode. But suddenly,that person stop me and take my pills.
"This pills... so nostalgic..."he said while he looking at my pills. He give it back to me.
"Why...why you give it back to me?" i asked, it strange if a person who want to attack me give my only weapons back after he take it.
"Because i'm not your enemy,i am your ten years later self"answered the man. Then, i make another ' HHHIIIIEEEEEE!!'.
No one's POV
"Here, i made you some green tea"Past Tsuna put a cup of green tea in front of Future Tsuna. He still dont believe it, his future self came without any reason? its crazy.
"Thanks,looks like I'm lucky today, look, the leaf are standing"Said Future Tsuna,he show his green tea with a proud face.
'Is came back from future can be called lucky?'thought past Tsuna.
"Yeah, because of this i can ran from my job,"said Future Tsuna while drinking his tea.
'D...did he read my mind? '.
"No, your face is easy to be read" Reply Future Tsuna.
"You are scary..."commented Past Tsuna. "I never thought i will be someone like this in the future".
"Haha, it's normal, right? Moreover, because of that Spartan tutor ..."Future Tsuna said in a gloomy tone.
"Yeah, that tutor from hell"said Past Tsuna with the same tone. "Your outfit...it means Im still become a mafia boss in the future ,right?".
"Unfortunately, yes"reply Future Tsuna. "Don't be disappointed, it's not so bad, after I became a decimo, now the mafia world wasn't as bad as it used to be".
"R..right..".
"By the way, when is this?"asked Future Tsuna.
"Ah, now is...,after the Arcobaleno Representative Battle"answer Past Tsuna.
"Okay...shit,now i must looking for another ways to get back to the future, since ten years bazooka will only take me there for five minutes"muttered Future Tsuna. 'And i never remember i have some guest from the future, maybe this is in another parallel world- uurgh,whats that?'Future Tsuna turned around, looking for who had kicked his back. "Reborn!".
"Dame Tsuna, now explain why there are your future self here?"Asked Reborn to Past Tsuna.
The hometutor is still the same, in a baby form with black fedora and chameleon on his head. He jump to Future Tsuna's head and sit on it.
"Ah,Reborn, i dont know how..."answered Past Tsuna.
"Hello Reborn, you see,its a long story,because of my carelessness"said Future Tsuna to his Ex-Hometutor on his head.
After that,Future Tsuna explain everything. And it make Reborn kick him ten times (By the way, Future Tsuna avoid it nine times). "You still careless,even as a Boss, looks like i must tor-tutoring you again"said Reborn.
'I swear I heard something before he said 'tutoring'!"thought Past Tsuna.
"Ahahaha...you dont have to...by the way, do you know any way for me to go back to my timeline?"asked Future Tsuna.
'He changed the subject!' thought Past Tsuna, again.
"We should ask Irie about this, ah, because it will confusing, your name is 'Otona Tsuna' now"answered Reborn,he jump from his pupil's head and walk to the door while Otona Tsuna and Tsuna follow him.
"Nice to meet you, Otona Jyuudaime!,i will always be your right hand man even in the past!!"said Gokudera with cheerful tone.
"Haha,its really fun, i hope my future self comes too!"Said Yamamoto, he laughing.
"It will be a disaster if your damn future self comes,Baseball Idiot!"Reply Gokudera.
"But, my future self is the one who teach you how to use flames"Said Yamamoto. It makes Gokudera grumble.
"Haha, so nostalgic, they rarely fight each other again in the future,i never thought i will watch this scene again,"muttered Otona Tsuna.
"Eeh..., can i have your attention?"Said Irie timidly.
"Sure,just talk,Shoichi kun"reply Otona Tsuna.
"Eh...Otona Tsunayoshi san, i'm really sorry,i cant send you back into the future,such a device cannot be created today, because ... there is no material,"Said Irie. Its normal,he is only a teenage now, how in the world he can make a time machine in that age??.
"Yabe..."muttered Otona Tsuna. "And i dont know when my guardians will realize if I disappear, Reborn locked me in my office for a week to do paperworks and this is only the first day, everyone knows that ".
"Thats mean you can't come back to the future until a week ?, and wait, why are you taking it easy even if you're locked up?"Commented Tsuna.
"Hem, its it will be your daily life when you inherit Vongola,"reply Reborn with his sadistic smile.
"HHIIIEEE!!".
"Alright,well, my younger self, do you allow me to live in your house until i can go back to the future?"Asked Otona Tsuna.
"How can i forbid you when you still the owner of that thing?"Reply Tsuna with confused face.
"Haha,you're right".
"Now, Dame Tsunas, its time to continue your training"Said Reborn with sadistic smile.
"Oy,Reborn, you said that this day theres no any training sessions!"Reply Tsuna.
"And why i'm include? I'm already graduated from the Pupil Title many years ago! "Otona Tsuna refused, she no longer wanted to experience Reborn's Tor-Training method again.
"Heh, this is the past,so you must follow rules here"Said Reborn to Otona Tsuna. Thats make Otona Tsuna only make a 'What the Fuck?' face.
"Well then,Jyuudaimes,good luck!"said Gokudera before he leave by jumping from the apartment window and using his flame to fly (What the heck, is he insane???).
"Me too, Tsunas,i have baseball practice after this, see ya!"Said Yamamoto. He open the door and leave the Irie's apartment.
"Uurghh...why this happen to me???" Tsuna whined.
"Tadaima..."said Tsuna while he open the door.
"Okaeri,Maman is cooking now,what happen to you guys?"asked Bianchi, she now tidy up the shoes at the door .
"Same as always, by the way, Bianchi... we have guest from the future,"Reply Tsuna.
"Lambo's Bazooka?".
"No,you know he already stop use it after his 6th birthday"said Tsuna. "You see...the guest is... me".
Tsuna open the door wider so Bianchi can see Otona Tsuna behind him. Well, Otona Tsuna is messy, same as his younger self,because of their Hell Training.
"Haha...tadaima, i guess?"Otona Tsuna laughed.
"Ara, that was very surprising, I never thought Tsu kun has a cousin"said Nana while she put the food on the table.
"Reborn is really bad at making reason,"Lambo whispered to I-pin, I-pin only smile because of Lambo's words.
"Shut up, Aho Ushi,"Said Reborn.
"Dame nii, Reborn teasing me again!"Lambo complained to Tsuna.
"I will help you if i can, Lambo,"reply Tsuna while he chew his food.
"Ah, Natsuko kun (That's a fake name that Otona Tsuna made with Reborn),where you will sleep tonight?"asked Nana.
"Uh..its okay, Nana san,Tsuna will share his room with me,right,Tsuna?"asked Otona Tsuna. 'Its hard calling kaasan with name and call myself in third point of view'Thought Otona Tsuna.
"Yeah, Kaa san, i want Natsu nii help me do my homeworks, hahaha, ahahahah,"Tsuna laughed.
'Aren't that obvious both of them are lying, after all, since when Tsuna nii / Dame nii have intention to do homework?! 'thought Lambo and I-Pin. They sweatdropped at their brothers bad act.
That night, Otona Tsuna borrowed Tsuna's Laptop. He was so bored so he spend his time watching Youtube. Because of his 'not sleep at night' behavior, he cant sleep. Reborn force Tsuna to do university level test so he now still struggling with the questions in front of him.
"Dame Otona Tsuna, your younger self having a hard time solve this 'simple' queations,rather than spend time watching useless video,why dont you help him?"Asked Reborn,he sit on Tsuna's bed.
"Yeah,yeah,"reply Otona Tsuna while he close 'his' laptop. 'When there is Reborn, it feels like i'm not the boss'thought Otona Tsuna.
"Lets see, what the heck Reborn, why you gave University Level Math Test to a middle schooler???"Asked Otona Tsuna. "Ah, forget it, i know your method".
"Geeh... i confused how you can survive until 25 years old,"muttered Tsuna.
"Dont know how, okay, if you want to solve this, use this formula, it will be easy if you follow the rules,"Otona Tsuna teach his younger self. While Reborn is smiled watching that scene.
Meanwhile in the future...
"Jyuudaime is missing!!!"Gokudera shouted at the mansion. He was came back from his mission and he want to suprised his boss but when he entered the office, there's nobody.
"What the hell?, no wonder he didn't ask for food and anything,"reply Reborn. "Is he run again?".
"No,we cant find him anywhere, Irie already checked all of the CCTV camera, and The Guardians and Varia also looking for him around the world,but he is nowhere, it feels like he dissapear from this world,"reply Gokudera.
"Shit,okay then, i'll go to his Office, maybe there are some clue,"Said Reborn while he run to his Dame Ex-Student's Office. He check Tsuna's desk and open it's drawer.
"There was so many suspicious thing here, why he keep it all on his drawer???,"Said Reborn.
"Reborn san,look at this, from the finger print, looks like Jyuudaime hold this before he missing,"said Gokudera,he activate his glasses program that can make him see detailed information on an item.
"Then,give that, 'unknown thing' to Irie, we must find that Dame Boss immediately!".
"What the heck, Hibari,why you attack me without any reason?"asked Otona Tsuna while he avoid Hibari's attack. He not in HDWM now,but he can easily avoid that with his Hyper Intuition.
"Hn, that baby said i can fight with you if i go with them to Italy next month,"answered Hibari.
"That Tutor from Hell," grumbled Otona Tsuna. "But you will never defeat me,Hibari, i'm stronger than you".
Otona Tsuna enter his HDWM, he attack Hibari from behind and Hibari resist Otona Tsuna's attack with his tonfa.
"Hn,I dont care if I can bite you to death,"Hibari attack Otona Tsuna with his Tonfa and Otona Tsuna avoid it. He attack Hibari and that attack make that prefect fall into ground.
"It's useless, right now, you can't possibly defeat me,"said Otona Tsuna,he go out from his HDWM.
"Hn, you win then,but i'll bite you someday, Sawada Tsunayoshi,"Said Hibari before he leave Otona Tsuna.
"You should said that to my younger self,not me!,"muttered Otona Tsuna.
A few minute later, Tsuna comes with his best friends, Gokudera,Yamamoto,and Enma.
"Aha,looks like you fought here earlier,"Said Yamamoto with his usual cheerful tone.
"Jyuudaime, i heard that Tonfa Freak attacked you,are you okay?"asked Gokudera.
"Well yeah,i'm stronger than him,so i'm okay,"answered Otona Tsuna.
"Thats right,Jyuudaime is the strongest!".
'Isn't that obvious???,he isy future self,after all,'thought Tsuna.
"Well, if i didn't see it with my own eyes, i will not believe Tsuna kun's ten years later self came from the future,"said Enma.
"Hello,Enma kun!"said Otona Tsuna.
"Yeah,its me, by the way, Otona Tsuna kun, who are they?,people...behind you..."Enma pointed behind Otona Tsuna. . He immediately look back and stare in disbelief.
"Hayato, Takeshi!".
That was his Storm and Rain Guardian. "Jyuudaime!!"Hayato ran towards Tsuna, and so did Takeshi.
"Haha,glad you're okay, Tsuna!"said Takeshi.
"How you guys can go here?"asked Otona Tsuna.
"Well, I came back from my mission too early,so i knew that you are missing. Then because of some reason, we knew that you traveled to the past, then we asked Irie ,Giannini,and Spanner to made Time Machine,"Answered Hayato.
"Wow,thats unexcepted,"Tsuna commented.
"Ah,is that you,Ten years ago Jyuudaime? sorry I didn't know you earlier,"said Gokudera.
"This is the first time i meet you,right,my younger self?,eh, hey Enma,i never thought you're so short,"said Takeshi.
"You dont need to say it loudly,"reply Enma.
"Hey me, nice to meet ya!,i always want to meet you,"said Yamamoto.
"Hehehe,same as me,".
"By the way,Yamamoto, theres no time to have a reunion, we must go back to our time before this time vanished,"said Gokudera.
"Eeeh???why?"Tsuna was very surprised.
"Oi, older me, are you kidding?, when we traveled to future, nothing happened,theres no way this time vanished because of that," said Gokudera.
"Hm,thats why you still a kid. Listen, when you use ten year bazooka,it still acceptable, but we use another thing that not Ten Year Bazooka, its...something that should not exist in this world,so it would be risky if we stay here longer,"reply Hayato.
"Hayato is right, looks like we must leave now. Tsuna, tell Rebon and the others that I have to leave now, good bye,"said Otona Tsuna. He take out something from his pocket, a pin shaped Vongola Crest. "This is yours now,take care of it,".
"Yeah...sure,".
"Take care of Jyuudaime, don't make him disappointed,"said Hayato.
"I will,".
"Haha,i believe you always can protect your friends,right?"asked Takeshi.
"You bet!".
"Enma kun, please always stand beside your friends,"said Otona Tsuna to Enma.
"I know," .
After that, the three guests from the future disappeared in a pillar of light. Leave the four of them in the cool afternoon breeze.
"Wow,that was a nice trip,"said Tsuna when he landed in Vongola Laboratory.
"Ah,Tsuna kun, glad you safe, "reply Irie.
"Yeah, and now i want to rest and eat my cake,".
"Looks like you cant do it, Vongola, The paperworks on your office...it has multiplied,"said Spanner.
"NOOOOOO!!!!!,WHY THIS SHIT ALWAYS HAPPEN TO ME??!??!?,"cried Tsuna.
-the end-
