-------------------------------------------------------

10 hours after kidnapping

Tsuna heard someone calling his name. Slowly, he opened his eyes and being welcomed by Nagi worried face.

" Tsu-kun , wake up. Are you alright?"

"yeah, I think so. Where are we?"

" I don't know. A few hours ago, I awake they still lift us but I manage to act like I was sleeping. I saw we entering an elevator and going to underground. Tsu-kun, I think we are kidnapped by the people at that bush. what should we do?" said Nagi.

"Hieee! are you serious? This can't be real" answered Tsuna.

"I am serious Tsu-kun. I'm scared! What they want from us?"

"I don't know either" said Tsuna quietly.

Suddenly, they heard footsteps that nearing the prison-like room. A minute later, reveals two man, who kidnapped them. One of them has red hair and wears glasses. The other one has blonde hair and green eyes. Tsuna and Nagi embrace each other and shivering. The two man scaring them.

"well, well.. They already conscious. Easy then" said the blonde man while opened the prison's door.

The red hair man enter the prison and grip Nagi's hand and force her to get up. " Follow us!"

"nooo! let me go!" scream Nagi

Tsuna push the red hair man and embrace Nagi. " I won't let you take her !".

"Spanner, take that boy with you. I will take the girl" said the red hair man who are already try to break apart Tsuna and Nagi.

"Alright Shoichi" said Spanner with a smirk and grip Tsuna's hand roughly. Tsuna can't help not to scream. His hand hurt. "Let me go! let me go! Nagi-chan!!!" scream Tsuna as he try to reach Nagi hand but fail.

"Tsu-kun!!" cried Nagi.

" Bring the boy to Byakuran-san, this girl will be next after him. " Order Shoichi to Spanner. Spanner drag Tsuna with him out of the prison.

'what are they saying? where are they bringing Tsu-kun? Tsu-kun, don't leave me alone'.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Spanner drag Tsuna to white room which full of fighting equipment and push Tsuna to a chair. Spanner push a button, automatically Tsuna's arm and ankles are strapped down by a metal. Tsuna start to struggling but vain attempt. Then he start to hyperventilate until he heard someone call his name.

"Tsunayoshi-kun, Welcome to Gesso's Laboratory. I can't wait to play with you " smile Byakuran.

Tsuna watch Byakuran with a weird face. 'who is he? how come he know my name? In what language they speak? I can't understand at all' thought Tsuna.

"oh.. It seems our toy don't understand us. Let's try our first invension. Spanner, take our first product" said Byakuran. Spanner obey Byakuran's order. He push a button at the wall, then reveal a cupboard. He pick up a box at the first row of the cupboard and bring it to Byakuran. Byakuran open the box , reveal red pills and feed Tsuna with one of the pills. Tsuna swallow it and suddenly his head hurt. It just like a hammer knock his head. "arhhhh!!" scream Tsuna, closing his eyes to reduce the pain. Byakuran only let his mysterious smile spread at his face.

After 5 minutes passed, pain in Tsuna's head diminished. He open his eyes and look back at Byakuran.

"now.. can you understand me?" ask Byakuran.

"yes, I can" replied Tsuna.

"so.. our first product success" grin Spanner.

"Now I want to proceed with our first objective with this boy" said Byakuran, smiled darkly.

Tsuna scared but he can't do anything with his hand and leg being strapped. He only let his head down to hide his terror when he see his captor's smile.

" Tsunayoshi-kun, don't hide your beauty face". Byakuran held Tsuna's face up and when Tsuna's eyes match with his eyes, he snap his fingers. The snapping sound seemed to send a deep echo that shook the rooms ever so slightly. Tsuna's eyes suddenly snapped into a widened gaze, his pupils shrank and slowly become dull. Lost all his emotion in it. Byakuran let go of Tsuna's face but the boy still look at Byakuran, unmoving at all.

" I want you to tell me everything you know about Vongola" said Byakuran with serious tone.

"yes, Master Byakuran" replied Tsuna, emotionless.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Two hours later, Tsuna have been sent back to his prison, where Nagi still stuck in there. Shoichi guarding outside prison, noticed his comrade, Spanner.

"This boy really help us a lot. well, Master Byakuran have already done with him for today. He wish to see another one" smirk Spanner while slowly push Tsuna toward Shoichi.

"look at his face, what an obedient kid" giggled Shoichi darkly, looking at Tsuna's emotionless face.

"before you take the other one see Byakuran-san, you should give that girl swallow this pill. It seems they don't understand our language at all" Spanner passed the pill to Shoichi hand. Shoichi nodded and sent Tsuna back to his prison.

Nagi heard the sound of people talking, which she recognised it. The voice belong to the kidnappers. She gives her attention toward the prison's door and she could see Tsuna was back still in a good shape.

"Tsu-kun" said Nagi, relieved. But Tsuna don't answer her. Tsuna never do this before. She run into Tsuna and shake Tsuna's body, want his reaction but Tsuna not respond at all. She watch Tsuna's eyes and shocked. There's no emotion in Tsuna's eyes. Tsuna just stared into nothing, barely blinking.

"what have you done to Tsu-kun?! " said Nagi, angrily.

" Oh, you're mad now. How cute of you. Now, swallow this! " said Shoichi as he force Nagi to swallow the pill.

" ughhh...... arghhhhhh! " Nagi swallow the pill and start to feel pain in her head. While Nagi withsanding her pain head, Shoichi pick her up and walk toward Byakuran's Laboratoty.

____________________________________________________________________________________________________

When Nagi opened her eyes, she already bounded to a chair in white room, the same room which Tsuna enter before. She noticed a man with spiky white hair and light purple eyes. He is wearing a white coat. The man smile at her and without a doubt Nagi smile back at that man.
"Hello Nagi-chan, I'm Byakuran. Welcome to Gesso famiglia. " Byakuran pretending to be a good man.

" Hello.. " said Nagi, shyly smile.

" so, how are you today? "

" I'm fine, thank you. "

then she remember something.

"are you the one who treat Tsu-kun before?"

"Tsunayoshi-kun? yeah, I am" replied Byakuran still with his smile.

"what happen to Tsu-kun? What are you doing to him?" ask Nagi, start to feel she in danger.

"nothing, just making him obedient. That's all" answered Byakuran, with dark giggles.

"please, cure Tsuna back. " plead Nagi.

" oh.. one day, I will let he go but with one condition. Do you want to make a deal with me? "

"..... what is it?"

"you will help me with my experiments"

thinking everthing will be normal back, Nagi accept the deal. "Deal"

____________________________________________________________________________________________________

The next day, Byakuran start to do his experiment just to see the effect of his equipment and product toward children. Byakuran ask for Tsuna but Nagi insist to do it for Tsuna. 5 hours later, Shoichi bring Nagi, who is unconscious back to her prison. Shoichi also prepared food for Tsuna and Nagi.

Tsuna just stared the food, don't even have intension to eat the meal. Not without Byakuran's order. He don't have feeling at all. Now he just a puppet to Byakuran who just obey whatever Byakuran's command. Byakuran also enjoy playing with his little puppet.

"Tsunayoshi, Byakuran-san ask for you" said Shoichi. Nodding his head, Tsuna get up and walk to the laboratory.

When he arrived at laboratory, Byakuran already waiting for him. He walk to Byakuran and bow.

"Tsu-chan, I'm glad to see you again. Here, take a seat"

"yes Master Byakuran." Tsuna nodded his head.

"have you eaten yet? " ask Byakuran. Tsuna shake his head.

" oh, I forgot you only will take my order, right Tsu-chan? and it has been one day you have not eat at all ".

Tsuna just nodded his head still emotionless.

" Sho-chan, please give our Tsu-chan his meal"

"Okay Byakuran-san" replied Shoichi, take a plate with meal for Tsuna and pass it to Byakuran

" Now, eat this. I need your energy for our next experiment" smiled Byakuran. Tsuna nodded again and start to eat his meal slowly.

After 8 minutes passed, Tsuna already done with his meal. Byakuran ask Tsuna to lie down on metal bed, while he preparing experiment tools. When Tsuna have lie down, Byakuran push a button which strap both of the boy's hands and legs with metal. Then he patching the heart monitor, the flame detector, and iv to Tsuna. Tsuna don't react at all when Byakuran show him several needle contain of coloured liquid, also when Byakuran start to inject him with the needles, allowing the liquid in the needle entering his veins.

Suddenly, Tsuna's body start to trembling, his mouth gapping for air but his eyes still dull. As minutes passed, the trembling of Tsuna's body become more stronger, the heart monitor's reading increasing and he already out of air. His face pale and blood start to flowing at his nose. Byakuran just watch all the effect and record whatever change that happens to Tsuna. After 30 minutes, the trembling are gone and Tsuna already pass out from exhaustion.

____________________________________________________________________________________________________

One week after kidnapping.

Nagi are taken to laboratory again today. She already awaken her flame, which is Mist flame in her first day being experimented. Byakuran injected her with purple liquid into her veins just as the same process as Tsuna's but she struggling more to escape that injection and she had a bit trauma against needle. The liquid that Byakuran inject her with help her produce a strong Mist flame.
Byakuran who are happy with his invension succesful, impatiently try them with others experiment.

"Good morning Nagi-chan" said Byakuran, happily.

"Good morning" said Nagi with inaudible voice. she scared. Whenever she look at Byakuran, it give her fear. Byakuran is a scary person behind that lovely smile.

"ah.. why are you scared with me? " ask Byakuran with a smile.

" I don't want to be experimented anymore" said Nagi, head up to look at Byakuran face.

"so, we need to cancel our deal then. Tsu-chan will never get back his emotion. " said Byakuran with a serious face looking right to Nagi's face. Nagi widen her eyes.

" noo! don't do that, Please leave Tsuna alone. you can make me your" plead Nagi, nearly crying.

"I don't want yours. You are fun to bullied and I just love Tsu-chan as my puppet" giggles Byakuran darkly. Nagi couldn't take it anymore, she cried hardly and pleading for Byakuran's mercy but Byakuran don't even hear her pleading.

"Now, let's start our experiment for today. you will not waste my time again. " said Byakuran with serious tone. He pinned Nagi at the wall and start to hit Nagi using bull whip. Nagi scream and cry as she feel wounds start to form in his petite body. The torturing continues until she past out.

____________________________________________________________________________________________________

Spanner sent Nagi to another prison. There are few child also being held there, they all have bruised all around their body. They eyes also as dull as Tsuna's eyes.

1 hour later, Nagi opened her eyes and try to get all her energy back just to sit up from her position but she noticed she not with Tsuna this time. She frankly search Tsuna around the room but only being welcome by few bodies of children around her. She try to ask a blonde hair's child but the child didn't respond to her at all. When she look at the child eyes, she see it dull just the same as Tsuna's eyes. she shake her head and retreat back.. " no.. no.. why all of them have the same eyes?!" Nagi screamed and let her face hiden by her leg.

20 minutes later, she could hear someone walking toward the prison. She just stared at the door, waiting for someone to come in. The door opened, revealing bloody Tsuna walking in the prison. The door closed again and there's a click sound which means the door have been locked.

Nagi run to where Tsuna sitting, try to look at Tsuna's wound. She don't care about her wound which already bleeding again, she just help bandaging Tsuna's wound using Tsuna's shirt. After she finishing it, she start to cry again. She could not take it when Tsuna lifeless like this. She missed the old Tsuna, this Tsuna just following Byakuran's orders without a care of his own body.

"Tsu-kun, please, come back. Don't let Byakuran do this to you. I couldn't stand it anymore watching you lifeless like this. I need you by my side, Tsu-kun. I'm alone, I need a friend that always support me whenever I feel afraid, just like you always do" Nagi hold Tsuna's face and match up his eyes with her. Tsuna just stared without blinking. His eyes still loss all it's emotion.

Nagi's tears fall down her cheek. She couldn't feel Tsuna at all. "please Tsu-kun" She hug Tsuna, worried he will gone from the world until she worn out, turned her entire world black.

____________________________________________________________________________________________________

Tsuna could hear someone pleading to him, but he don't know who's voice is it. He still in daze in his own world until he could see someone face in front of him.

'who is she? why she crying in front of me? why her face look so in pain? what happen to her?'

Then he heard one last sentence "please Tsu-kun".

'Tsu-kun? is it me?' Tsuna try to recall his memories. Suddenly, his eyes widen and his pupil show clear emotion not dull anymore.

'I am Tsu-kun, I'm Tsunayoshi Sawada. This girl is my dear family Nagi Spade. how could I forget about important things. '

"arhhhhh!! " scream Tsuna, he now could feel how hurt his body are. He hug Nagi's body back and try to withstand his own injuries. He look at the prison' s door and he could see a silhouette of a girl watching them. He recognised that physique. 'It' s Kyoko! how can she be here? ah, her power. I forgot. I need to give her clues. ' but he before could say anything, the pain already separate all around his body.

"help us... hurry up... underground" and darkness consume him.
