Both Tsuna and Reborn return before sunset and saw everyone making such big ruckus. Mysteria was on the corner, drinking her favorite red wine while the others beating Rick for some reason. They also saw redness to Lal as she was… angry… while Yuni seems to be out on her world because her eyes were spinning around.

"Welcome back Reborn, Tsuna." Mysteria was the only one who greeted. Reborn nod to return the greeting while Tsuna asked, "What happened?"

"No need for you to know." Mysteria simply said as she pull down her hat before drinking again.

Reborn observed Rick for a moment before sigh, "He must have talk about that again."

"What do you mean?" Tsuna asked, curious. Hearing the question immediately, Rick escaped and took Tsuna's hand in delight.

"Oh how happy I am someone is trying to know the true revelation of humanity! People here don't want to hear it but I would gladly tell you if you wish to know."

"No he doesn't!" Reborn said, unconsciously irritated.

"I will tell you now my friend." Rick said as he lean closer to Vongola Decimo. Tsuna found it creepy as he whispered, "You see the g-"

He was cut off by immediate response of double smack in the head by both Mysteria and Reborn. "Don't fill him up with your pervert civilization!" Both in union said.

Rick had roll around three times and sat up immediately, "What are you saying!? For a man and a woman to have a child, it was natural for both to have se-"

He was shot by Raven this time, "Shut UP!"

The others beat him up again. Tsuna glance to both in question.

Reborn just sigh, "No need for someone like innocent as you to know." Reborn glance away in embarrassment. "There's no need for you to have a same illness as mine."

'Oh, Reborn was phobia-tic to girls.' Tsuna remembered, so he decide to leave it be.

Mysteria sigh in relief and turn around to return to her sit but she felt something within her. It was tremendous pain, her heartbeat was too strong as she can hear it all over her body. Her heart and mind aches in pain, her walking was swaying.

"Sensei?" Reborn questioned as he noticed something wrong to his Sensei.

Mysteria kept hearing her heartbeat and her whole body soon reacted in great pain as her consciousness slowly fading but kept her standing. Mysteria not knowing why finally noticed a glowing mark on her left arm. There was like a seed on her lower elbow and there were branches growing up. There were already two leafs and now it was spreading again, producing another leaf to her arms.

'N-not… now… ughhh!' Mysteria though and then finally, she shouted in pain which surprised everyone and turned to her direction who's sweating dramatically and finally fall down on the floor. She had completely lost consciousness.

Elaine and the others are in panic, same to Reborn as they immediately went on her side.

"Sensei! SENSEI!" Reborn shouted in panic.

Tsuna was shock, Reborn was panicking and so's everyone. What just happened to her?

Shing was the one who ordered everyone, "Doranbolt carry her, Rick ready your things and check her condition, everyone give ways now!"

They did as they were told. Doranbolt immediately carried her and run, heading to her room with Reborn on his side. Reborn noticed the mark on her left hand, the leaf had increased. Reborn looked in horror and released a loud 'Tch'. He doesn't like it, what can he do to release his Sensei from the contract?

Rick immediately took his belongings and followed Doranbolt. They also followed, worried.

Arriving on the second floor, Rick, Silver, Shing and Raven were the only once on her room while the others wait on the living room. Reborn was restless, he can't stop worrying for his sensei. Tsuna was the one who's trying to calm him down and assuring him she will be alright but even he himself wasn't believing his own words. His Hyper Intuition was reacting, something about this case was related something which he's looking for, something that he can't point it out.

Yuni and Elaine ware giving them drinks to lessen the tense, even just a bit. For three hours finally, the door opened and saw them walking out. They stood up and went to them.

"How was she?" Elaine was the first one to ask. Rick sigh and answered, "She's fine, we didn't found the reason why that happened to her. There was no sign of illness or anything. She just experience tremendous pain all over to her body and so on."

"It wasn't from the that too which we found it questioning. No matter what kind of thing it is, it will danger her life." Raven said which they found it shocking.

"No illness or anything? Not even poison? Wound? Anything?" Doranbolt questioned.

They nod, telling him yes.

"Wait, no illness, poison and so forth… it was like how Reborn died." Verde said which earns them a surprise.

Tsuna finally understood. That's right, it was Reborn's case. But, what does this mean?

"T-th-the… c-co-cou-countdown..." a low voice murmured beside Tsuna.

Tsuna turned to his side and it was Reborn. Reborn seems to be in horror, afraid about something. He's gripping his hand too hard and he's glaring too much on the ground and his breathing was fast.

"Reborn... Reborn!" Tsuna called out loudly as he shake the panicking teen which made Reborn almost jump in surprise. He slowly looked to his side and he saw the worried look of Tsunayoshi. "Reborn breath in… what's wrong?" Tsuna asked, really worried for Reborn.

Reborn was still panicking on the inside and still afraid about something. Too much stress and thinking made him collapse which thankfully caught by Tsuna.

"Reborn? Reborn!" Tsuna called out but won't wake up.

Rick quickly took Reborn and put him on the couch, he check on him and told them, "Too much stress and worries. He just caught a panic attack but don't worry, he just needs a rest."

They all sigh in relief. Elaine immediately took a blanket and places it around Reborn.

"He must have been worried too much for Mysteria, even if she was a terror and sadistic teacher, she was just like a mother figure for Reborn." Elaine said, worried for Reborn and Mysteria.

"Don't worry Elaine, he will be fine, and so is Mysteria." Doranbolt assured his wife.

Skull was worried for his Sempai, he wasn't use seeing Reborn like that. Verde who has a rivalry on Reborn somehow can't calm himself. He doesn't like seeing his rival so weak, not worthy for him to be so called Rival. Yuni was worried for both of them and prayed that they would get better, same for Colonnello and Lal. Viper wasn't acting much but he too was worried, even if he won't admit it to others.

Tsuna had a feeling Reborn knew something that cause Mysteria to be like that. He wanted to ask him but end up like this. He will wait and let Reborn rest and so is Mysteria, even so, he will do whatever it takes for him to learn the truth. He wanted to know why Reborn died, he wanted to know everything.

Later night, Reborn woke up and immediately went to Mysteria's room. Good thing he was alone with her. He quickly went to her left side and checked her arm. He did something which made the mark on her right arm came out. There were three leafs. He clenched his teeth, not liking it at all.

"Reborn" A weak voice called out. He immediately looked to her, Mysteria woke up, giving a small smile to her apprentice.

"Sensei" Reborn called in whisper.

Mysteria chuckle and raised her hand, Reborn took her hand.

"Don't think I'll die early idiot." Mysteria said in silent voice.

"B-but… it's…" Reborn can't say it completely, Mysteria sigh but gave an assurance smile, "I'm fine, don't worry."

Reborn kept quiet for now and finally asked hesitantly, "S-Sensei… w-wha-what d-did you… loss?" Mysteria understanding that thought carefully as she checks herself mentally. She sighs, knowing what it is.

"I'll tell you, after I explained to those people who were eavesdropping us." She said as she was pointing on the door.

The door opened, showing Tsuna and the others. Mysteria sigh again and tried to get up but it seems she still can't and Reborn helped her sit. She gave a silent thank and faced them, silently telling them to come in and so they did. They silently went to their place, waiting for the explanation.

"Do you want to learn what happened to me?" Mysteria asked and everyone nod.

"Mind telling us everything Mysteria-san?" Yuni asked, serious and determine on wanting to know everything.

Mysteria smirk on sight, "Very well, first is this." Mysteria showed the seed and leaf marks on her arms. "Beautiful it may be but it has a hidden deadly once. It was my symbol of my contract between me and the Dragon Demon of the underworld."

"Dragon Demon?" Skull questioned and she nod. She continued her explanation, "It happen when Reborn and I rested on the far village hidden behind the mountain here in Italy. They were secretly using visitors from the outside to offer their flesh and souls to their beloved demon god or something. Since we both came there, they able to use both of us to become their sacrifice on their so called god."

They were surprised, they were about to ask more but Mysteria continued her story.

"We were both too late to run away from it, sending us on the underground world where demons were living. Heh, we even fought against them and damn they are too inhuman kind to say. We used that opportunity to train ourselves there but at the same time cautious on whom we're fighting against." She said, seems remembering that time was her best moment.

Reborn just sigh, remembering that surely gives him a hard time and gave him a many times near death experience at the same time glad, because of those creature that he somehow had gain more strength and experience when comes to fighting. She continued her story.

"We fight, at the same time search for a way out. For long days with those creatures we finally got a way out, and we knew it wont be that simple but we never thought it would be a horror one." Mysteria became darker as she remembered that time. "To return back, we have to meet the ruler on the underground world, the Dragon Demon. We searched until we found him. We able to have a discussion without any more necessary means of fighting until he told us a way out which shocked us."

"What would that be?" Lal asked as sweat slowly fell from her cheek. Mysteria gave them a straight look, "The price for our way out is haft of our lives and a painful death."

All eyes widen in disbelief. Haft of their lives and painful death? Are they... serious?

"The painful death means having a countdown. Once the counting started, something will loss within us, depending on what it is. When the countdown reached to five, you'll experience the most dreadful pain until you die." This time, Reborn told them which shock them all even more.

Mysteria continued, "Normally I will choose to take everything instead but that Dragon won't let me. I will have it but I'll be the only one who will get out, not Reborn. It really irritates me as I want to blow his head but this guy, Reborn had accepted it and end up both of us paying the price. So both of us got out from the underground world and received the seed within us, the symbol of our contract to the Dragon Demon."

Reborn showed his right arms and the contract within him. It was still a seed, still not growing up. Tsuna felt dreadful, that would only mean the reason of his death… was because of that.

"We return back on the same village that sent us there. They're surprise since none of the sacrifices had ever returned from the underworld. Sensei rampaged through anger and so I join. We didn't kill anyone but we had destroyed their beloved village. We didn't care to their cries, we didn't care to their begging. All in our mind is how angry we are we end up having the seed just to get of there." Reborn told them, not showing any regret at all.

"If wondering where those people are? They were already scattered around the country and their belief had cease due to us. I really don't care about them now." Mysteria said to them, if ever they are thinking of searching them and kill them.

"Did you find a way to destroy that seed kora?" Colonnello asked, little hopeful.

"If we have, Reborn wouldn't have died on your time Colonnello. Since we don't… you know what it means.?" Mysteria said which made them depressed.

They can't do anything, they can't help them at all.

"Were you keeping it from them?" Viper asked and Mysteria nod, "I told Reborn not to say a single thing about the seed as well."

"Then mind telling us what is this losing Reborn had said to you before we all spoke here?" Verde questioned, remembering their conversation before they were found by her.

Mysteria was silent for a moment before she replied him, "Remember what Reborn just said? The countdown is also something that takes something away from you until it turn five. Seeing I have three already, I had lost three as well."

"What would that be?" Fon asked this time.

"Emotions, I'm losing some part of my emotions." Mysteria answered which surprised them. She continued, "The seed had connected to my emotions so it will take something away from me. Before, I had lost my emotion called love and sadness. Now, I had lost my emotion called hatred."

"Hatred?" Skull echoed, not understanding at all. Mysteria gave him a clear explanation, "It means I am no longer capable to feel hatred Skull. I'm now immune to produce hatred to anyone else."

"Then same to love and sadness?" Skull asked more and Mysteria nodded as yes.

"Two countdowns are left and I can only guess two more emotions will be loss. My happiness and Anger. Once those two lost, maybe I'm just an empty shell human being." Mysteria said with a sad smile, although that smile seems empty.

"Then… what would be Reborn's countdown?" This time, Tsuna asked. Mysteria became silence for a minute while Reborn was waiting for her to respond until she answered. "Senses, his countdown is senses, according to my observation to all your memories."

"Senses? You mean like his hearing, sight and so forth kora?" Colonnello asked in disbelief but she nod, telling him yes.

"My senses huh..." Reborn murmured to himself.

Mysteria spoke, "His first countdown must be either his smell or taste. His fourth one must be his sight, seeing to Tsuna's memories that his eyes had turn to gray which was usually a black one."

Remembering the day Reborn had left him, yes, Tsuna noticed the eyes of his changed. He was unable to ask him about it.

"Then at that time… his last senses that was working was…" Tsuna trailed off and Mysteria finished, "His hearing."

Everyone stayed quiet, processing everything they had learned from her. From all of them, Tsuna was the most depress one. Reborn found it questioning and was about to ask why when Mysteria spoke first.

"Now that you know, mind if I speak with Tsuna alone? I need to speak with him about something and I would love everyone to leave the room." Mysteria glanced to her apprentice, "You too Reborn."

They found it questioning but nod, respecting her desire. Reborn was the most hesitant but then comply as everyone went out the room, except Tsuna and Mysteria. Once they do, Mysteria began their conversation.

"Tsuna there is something I had tried but failed. This time, you may able to succeed on my place, but... You will have to decide whenever you'll do it or not because there's something here that you might regret." Mysteria told him seriously which made Tsuna questioned.

Tsuna was thought for a moment before speaking, "Tell me."

After a long hour of discussion on the two, Tsuna finally went out the room. All ex-Arcobaleno approached him.

"What did she say kora?" Colonnello asked Tsuna. Tsuna gave them a small smile, "Sorry guys, those are only between us."

They wanted to persuade him to tell more but was interrupted by Reborn on the sudden question.

"Tsunayoshi, by chance, did you know my name?"

'Uncle Reborn's name?' Yuni questioned mentally, she never heard about this before.

"At that time, you know my real name that supposedly only me and Sensei knows. Tell me, do you know my name? How did you know!? Knowing Sensei, she will never break a promise. She swore in exchange of me only telling my real name to another person who I will love until I die." Reborn said which earned them a shocking expression, except Tsuna who's taken aback a little.

Tsuna gave a force smile, "I know because you're the one who told me Reborn." Reborn raised his eye brow, not believing at all. "Me? Why would I tell you my real name?"

"Would you surprise if I said I love you." Tsuna said boldly which surprise them even more.

The ex-Arcobaleno ware aware of Tsuna's feelings for Reborn, same to the Guardians since its actually obvious every time they're with the brunette. They wanted to figure out Reborn's feelings for his student whenever its still a teacher/student relationship or he's on another level like Tsuna but in the end, they failed.

Reborn's shoulder was dropping, not believing that someone who will say he loved him was a boy! Looking closely, he wasn't joking at all.

"You kidding me." Reborn said, still refusing the fact he will fall in love to a man of all people. He had a phobia to girls, yes, but it doesn't mean he's a gay.

"Want me to tell you, your real name?" Tsuna asked, giving a brave expression that he's serious. He still loves Reborn and its already too much for him to hold back his feelings, even if the Reborn he's seeing is his younger version.

"Tell me." Reborn said in seriousness, meeting Vongola Decimo's seriousness. He pointed his right ear, "On my ear. If you truly know, I rather want only you to know it, no one else."

Tsuna nodded in understanding and approached him. Tsuna gathered his courage on the serious deadly look of Reborn. He gulped and went near to his right ear, he whispered his real name.

Reborn at first was shock that he indeed knew his real name, until something struck within his mind. His eyes were getting wider, something was coming in to his mind. Tsuna took the opportunity to see him straightly to see his reaction. Reborn looked straight. After a long minute of staring, Reborn quickly took his hand and pulled him to his room. Reborn locked the door, not wanting anyone else to disturb them.

Tsuna found it questioning on why Reborn suddenly brought him to his room. He's about to question him when suddenly, Reborn hug him tightly. Reborn didn't spoke but instead, he pull him closer, tightening his hug to Tsuna.

"Reborn?" Tsuna questioned, completely surprise on Reborn's action. For long silence, Reborn finally spoke, "Tsuna… Tsuna..."

"Reborn I'm here." Tsuna said, answering his calling.

Reborn finally released him from the hug but never let him go. Reborn looked to Tsuna in soft eyes… and sadness.

"Tsuna… I don't know but… when you told me my name… a memory had surged within me… my memories from the future… they went to me." Reborn told him which surprise Tsuna. He continued, "I felt my love for you… how much I had indeed love you… but with this curse and my life… I have no right to tell it to you at all."

"Reborn" Tsuna called out, he doesn't know which one to react, to be happy because Reborn truly love him for so long or be angry and sad because of that seed within him, he can longer stay by his side.

"My feelings from the future came to me Tsuna, although I can tell it was just a moment." Reborn retold, its clear he doesn't like the way the future went to him. He was sad and angry to himself.

Tsuna hugged Reborn, feeling him right now as he had a chance. Reborn happily return back that hug. He never expected in just memories, it gave him too much feelings for the brunette.

"I miss you Reborn… so much." Tsuna whispered, his tone was showing how he truly loved Reborn that it truly pain him on how he died.

"While I'm sorry Tsuna… I left you in pain… I really thought it was just me but… I never thought you feel the same way as I do… I'll tell you Tsuna, your confession made me the most happiest man in the whole world… even so… I still left you… I'm truly sorry Tsuna." Reborn whispered back. He too felt too much pain and guilt. He truly doesn't want to lose him.

"I finally know the reason Reborn, there's no need to apologize. I'm just mad at myself that I… I never noticed your pain."

Reborn smiled a bit, "No need, I did cover it well to everyone, even to you."

"Reborn"

Reborn pull out the hug and looked at him in eye to eye. "Tsuna… can you be happy without me?" Tsuna shook his head, "No, I can no longer be happy without you Reborn."

"But you have to Tsuna, its my wish. I want you to be happy, I don't want my death to be your own despair. Tsuna… please… understand me."

"I know but… I know but I can't! I can no longer happy without you by my side Reborn! I… I want you." Tsuna finally began to cry.

Reborn wiped his tears with his two hands, "Don't act like a girl Dame Tsuna, you're a Vongola Boss remember?"

"B-but I'm still human Reborn… Its still too much for me!" Tsuna said while crying. He doesn't want to let go this moment. Reborn was same to him... still, "Don't be such a Dame Dame-Tsuna, it's already impossible for us to be together. Find someone that would make you happy, more than I do."

Tsuna shook his head aggressively, not agreeing at all.

"Dame Tsuna"

Tsuna looked at him in his teary eyes and Reborn lean closer, leading the two to kiss. Tsuna was surprised at first but happily return back the kiss. It was so different than the last time Reborn had kissed him. This is how Reborn truly kiss when he still had his feelings.

Reborn lick the bottom lips, asking for entrance and Tsuna happily did. Both had battle on dominance and in the end, Reborn had won and taste him. Reborn can taste the sweetness which he gone deeper to make Tsuna moan in pleasure.

Tsuna felt like everythings a dream, a dream that soon will disappear. He wish for the time stop, feeling more on Reborn. In the back of his mind, he wanted to question how could a teenager like Reborn could make him feel too much good and experience.

After a long kiss, the two departed. Both pants from the kiss, Tsuna's cheeks were burning from redness while Reborn already had a lust reflecting his eyes.

"Reborn" Tsuna called out softly to him.

Reborn smiled on sight, "I love you Tsuna, be happy… for me."

After saying that, Tsuna began to glow which surprise himself. His hyper intuition was telling him something, something that he doesn't want to happen, not now.

On Mysteria's room where all the ex-Arcobaleno located, they were still talking to Mysteria when they all began to glow like Tsuna.

"Wha-what's happening!?" A panic Skull asked.

"It seems your time here is finish"

They turned to Mysteria in question.

"What do you mean?" Fon asked.

"Just as I said, your time is up. You will all return back to your present." Mysteria told them.

"Already huh… but I wonder why so suddenly?" Yuni asked.

Mysteria gave a small smirk and answered. "Because your purpose is finally over."

"Over?" Lal questioned.

Mysteria explained, "From the looks of things, your purpose of coming here is to let you know what Reborn's life really is and so is the reason of his death, the seed of contract. Everything makes sense you see, some of the secrets we are keeping are coming out. The growth of my third leaf is not a coincidence, it purposely quicken the growth for all of you to witness. I notice how Reborn answered your questions about his life. From what I know, he will never tell to anyone his purpose of training and living which is revenge but he told you without him knowing it himself. In other words, everything is being controlled by someone, the person who sends you here in this very time."

Verde narrowed his eyes, "Do you have any idea who would that person be?"

Mysteria became silence for a moment before answering, "I do… and that would be me."

"YOU!" A shocked Colonnello said as he pointed Mysteria.

Mysteria chuckle for a bit, "Not my current me but maybe my future self. I have no idea how to do such thing and I would find that answer if I would search for it. I sense that this is supposed to happen so I decide to do the same thing in the very near future. Glad to meet all of you by the way."

They heard a bell, except Mysteria. The sound of the bell was familiar… it was when they were about to be transported, they heard a bell ring three times before something below came out and suck them into the light.

"Wait, can we change the future? Can we do something to save Uncle Reborn?" Yuni asked in desperate. Mysteria shook his head sadly even so empty, "I'm sorry but… you will all return back to your rightful time, where Reborn is dead. You can't do anything."

"No way..." Yuni said in low tone, not liking at all.

Inside to Reborn's room, Tsuna was desperate not to let Reborn go. He doesn't want to come back, he wanted to stay by his side.

"Tsuna" Reborn called out. Tsuna was crying without end, "No, I don't want to lose you… Reborn I don't want to lose you!"

"I too Tsuna but that will never happen. You will be returning back. Then promise me that you will recover for me and smile for me. I love your smile Tsuna, I want you to be happy without me… Live for me… Tsuna." Reborn said as he hugs him tightly.

Tsuna heard the second bell and looked to Reborn in eye to eye. He quickly wipes his eyes from his tears and gave him a desperate look, "No Reborn, I want to be happy with you, I promise that, I will make you come back to me… we'll meet again."

"Tsuna?" Reborn questioned, something tells him he had something in mind that he might not like it.

The third bell ring and the circle came out below them. Tsuna and Reborn gave their one last kiss before Tsuna was devoured by the light and vanish, leaving Reborn alone on the room.

Down on the Tavern, everyone was there and then their eyes widen for a second and blink three times. Something in their mind was forgotten that they can't pinpoint it out.

On Mysteria's room, Mysteria was touching her forehead, there's a white orb in his hand and disappeared. She deeply sighs then felt someone coming. It was Reborn. She gave a small smile and asked.

"Something wrong Reborn?"

Reborn seems confuse for some reason before speaking his confusion. "W-well… just that I felt I have forgotten something… what did I do for this last two days?"

Mysteria gave a confusing look on why he had questioned it until she figure something out and smiled.

"Don't mind it, can you go and tell them I'm awake, I'm sure those guys downstairs are worried."

"Oh, you mean Elaine and Doranbolt? Sure." Reborn went out the room.

Mysteria sigh and think carefully. From the looks of things, all their memories about meeting the future Arcbaleno and future Vongola Decimo had been erased to everyone's mind. She was no exception but failed. She knew, if its her who sends them here, she will make sure to erase everyone's memories, making sure no time paradox will ever happen to damage the time.

She was very thankful to her power, the power to manipulate memories. She's the only one who remembered because she able to save her own memories before they returned back in time. No one remember them coming here, even Reborn himself. Its cruel but it is something that is needed to done. She sighed and looked outside the window where the sky had a clear sunrise.

'The time will continue to flow no matter what… Tsuna… make a decision that you will never regret.'

I do not own Katekyo Hitman Reborn
