A prison.

No, let me rephrase it, a prison-like room was what greeted me when I'd wake up. A white room, with just one boring white bed and a toilet in the left corner of the room. A metal door that rarely seen.

I bring myself up from the floor and stumbled a little of a sudden light headache. I groaned in anger and frustration.

'That Pineapple... just what is he showing me.' I thought while ruffle my hair. Is he gonna show me a weird dreams? Scary dreams? A zombie? Oh how I don't want see the last two.

Then, a sudden voices of a human can be heard from outside. A vague one but slowly It's starting to get louder and It's starting to get closer. Then, the door of the room I was in opened and a little boy was thrown roughly onto the floor as two people in outside close the metal door with a beeping sounds before it stop.

A groaning from the boy make me jump a little, I take a better look at the boy that still in the floor. I somewhat recognize the boy, a indigonet hair, and a pineapple-like hair一Wait.

...It's a pineapple-like hair!!

Which means...

"Tsk. Those bastards... I swear I'm gonna make them regret it." The boy said under his breath as he stand up from the floor.

I gasped.
It's him.

It's... Mukuro.

...

Why the kid version of him are so cute?! Damn it Mukuro, why are you became not cute now.

As I fangirling on the kid version of Mukuro, he walk to the bed and laying down. He sighed heavily with a ragged breath. I stopped my thoughts and come closer to him. I frowned and narrowed my eyes.

I just noticed he have many bandages around his body and his complexion pale, his eyes that have a very heavy eye bags. He needs rest.

I attempted to pat his head and be in his side till he sleep. But, when I tried to pat him, I can't touch him and just sliding through. I blinked as I tried it once more and It's still sliding through his head.

I confused and take a look on my hand, It's transparent.

I just realize that my body right now are transparent. I widened my eyes in surprise but soon sighed.

'Let's think what's he's showing me. There's him but when he's child. He wearing a white clothes, and this room...'

I walk closer to the door and see if I can walk through of it considering I can slide through Mukuro earlier. I walk to the door and got out easily like a ghost. Being a ghost must be so easy.

I'm somewhat want try other things to do with my states right now, but I don't have times to do that. Maybe I have plenty but, I will use it to observe Mukuro.

The outside of the room was a hallway, with nothing except many rooms besides each other. I walking to the end of the hallway before turn when It's the end of it, and there's a room which not the same as the others. I walk closer to there and was gonna take a peek inside before a sudden scream came from inside the room. A high voice, which means, a kid scream.

I gasped in horror and realize about where am I right now.

'...Estraneo Family headquarters...'

That answer of this place where its like a scientists would doing a experiments, no, it is like that.

'Estraneo's Family... which means... is this Mukuro memories?'

"It's seems so."

I screamed in surprise at the sudden voice in my side. I glance at my side and let out a heavy breath that I hold from surprise earlier.

"...Marina... don't surprise me like that."

"Ah, sorry. I just couldn't see a right timing to show up." She said while laughing apologies. I pouted at that and go back focus. Wait.

"...Marina?"

"Hm?"

"Are you not gonna ask why I know about estraneo family's even though I never hear about it in my surrounding? And... others things."

I wondered about that, before I passed out Mukuro said that I knows his name even though I supposed to not know about that, he assumed that Marina told me about him but, actually she not tell me about him. I'm sure Marina been inside me since then, and been watching me inside.

Also... I'm sure she heard that I'm a reincarnation from other world. People usually would confused and ask a lots about that.

I'm sure It's weird and people would have many questions connected to it, but why...

Marina thinking inside as what answer she will give to her. As she made up her mind, she smile to me.

"You will know sooner or later. Mahiru, you can told the truth to me whenever you ready. I'm waiting whenever is it."

My lips parted and widened my eyes, I not used to those kind of words. In my past life, everyone was a push-over. Even though I can't tell them the truth at the time, they still pressure me over that to tell them the truth. It was so annoying that I decide to not talk about anything unnecessary. It's the first time that someone told me I can wait for it.

Are you guys thinking what about Tsuna and the others? It's not the same. Reborn as always want to find my secret, well... maybe except Reborn they're the same, but It's the first time someone told me that directly.

I can't think of any answer so, I just thank her with a small voice. She just smile warmly to me.

"Kay! Let's go back focus, and observe Mukuro then. It's better than having nothing to do!" I said as I walk back to Mukuro's room earlier.

Marina looked at me with a sad eyes and mumbled something.

"It's not like I'm waiting for your answer of that, but, I already know about it. Sooner or later... you will know about yourself. I wonder will you able to take all of that..."

"Marina?"

"I'm going!"

______________

Some times passed and now we're in beside Mukuro. It's morning and he eating in the table where there's a lots of kids. It's estraneo so, it maybe not a strange things for them. But, there's just too much kids than I expected.

Beside Mukuro were Chikusa and Ken as expected.

I just noticed it while ago but, Mukuro  does not have a odd eyes. Both of his eyes are the same color. Which means... We seeing the memories before he acquired that power. The Six-Paths.

I look at the breakfast food and grimaced a little. A rough bread, and a plain soup with a vegetables that roughly placed on a bowl not looking delicious. I let out a dissatisfied growl under my mouth, just why they give them that, obviously that will not make them satisfied. It's even worse than Hospital foods.

Hospital foods? Yea, I hate it. The flavor in there are just too plain, and very light, and always cold. The flavor are not strong and I barely can tell the taste! Just why hospital foods!

"Just why they gave them this disgusting food. It can't satisfy their hunger and their stomach, that be making their immunity down instead." I said while watching Mukuro and the others eating it with a dissatisfied face.

"That's true. For a scientist, usually they targeting a healthy living being for their experiments because in the end it will be easier to see the change. Except... this place are different than a normal scientist. They don't care about them and just care about the results of their experiments." Marina commented glancing around their surrounding.

"Of course It's not normal! It's Estraneo we're talking about! They just care about their experiments and decide to just experiments their own child. Just for their reputation and to be acknowledged by the world. In the end It's just their ambition, greeds, and lust that what caused this."

"Well, we're humans."

"And I hate humans. I already lose my belief of humanity since long ago."

Marina just raise her eyebrows in question. "So you mean, you hate Tsuna and the others?"

"Of course not! I'm talking about the humans that are foolish and just want power just for their greed!" I retorted in slight anger. Marina just hummed in response and not saying anything else.

"So, in others words, you're scared of Human Lust." I cannot say anything back because she's correct. I lowered my head and waiting for the other to say something.

"Well, let's continue this talk on other times. Now, we just need to focus on Mukuro."

"Right..."

I compose myself and let out a big breath. Few minutes has passed and Mukuro that already done eating are now called by a guards. Mukuro face instantly became dark and quitely obeying the guard and go somewhere. We quickly go to his side and notice as we go, the hallway became very quiet and there's less rooms.

They then stopped in front of a door that different than the others room we passed.

The door open automatically as they push Mukuro to the inside roughly. I narrowing my eyes. Inside the room was like a operation room, like a typical hospital. There's many mechanism for many things, a shelf with a equipments of operation inside it. But, just one person is in there while smiling creepy.

"Good morning subject 069. Now, shall we start the check-up?"

A brown hair with a green eyes, he's wearing a white coat and a glasses. Mukuro just glaring at him, but obeyed. He doesn't have any power to counter-attack him after all. He then walk closer to him and lying to the mattress in the middle of the room.
His hands and legs then tied up by a metal and he can't move.

I widened my eyes seeing that. So you can't run away huh, what a typical move.

"Today check-up are a little special you see... If you able to success it, I will give you a reward! That is... if you being obedient." He said while inserting a fluid to the syringe.

Mukuro just not answering him and silently glaring at him.

"If I ask for freedom are you gonna let me?"

"Yes, of course. You will..." The man said with a creepy smile plastered on his face. Mukuro was believe it easily and let him inject the fluid from his arm. I was mad, he inject it to a child without any alcohol to rub it first!!

That's will be so hurt! And he still a child!

I was mad at how Mukuro trying his best to endure the pain.

"That bastard... I'm glad Mukuro kill him in the future and destroy all of the Estraneo's Family." I gasped in realization after saying that. I glanced at Marina that not calmly watching it and seems not noticing about me. I exhaled a deep breath.

A few minutes passed, and Mukuro's became acting strange. He's screaming in agony and trying to escape from there with a aggressive moves. I step back a little and watched him hurting and screaming.

The man just standing there watching him with no emotions which I'm really angry of.

We still watching him screaming, crying, in agony. I cover my ears can't really take the loud screams. It's hurts. Inside, It's so hurts. It's so hurts not being able doing anything and just watching it.

Even so, I continue watching him. Even though It's hurts, even though I can't take it, I have to watch it. There's must be a reason why he showing me this, and I'm going to see it till the end.

__________

It was hell.

What he's been suffering are just like a hell, no place he can feel peace. He just continuing kill and kill to survive. There's no mercy in his face, just continuing kill just for his pleasure and to alive.

He's finally escaped from that Famiglia for 4 years with Ken and Chikusa. But even so, what he living was hell. Reality not kind as they expected as soon they escaped.

They did not getting any job, even money they don't have much to buy foods. That lead them to a homeless people, and just wandering around to get a job and living peaceful. Just peaceful that they want.

Some times passed and they managed to get a job, not a normal job though. They became an assassin. To kill people, and get very big amount of money. They didn't really want to do it, but they don't have any choice back then. They was just desperately want live, and they need money for it.

They living without any concern of money because of that, It's not really a peaceful live, but at least It's better than in that place.

I was watching it throughly. It was so hurt to the point I feel want leave from here. If It's were me, I no doubt don't want live anymore and kill myself.

Marina keeps assuring me with rub my back and hugging me to keep strong watch it.

That help me very much.

As he said, It's really was a hell. But, isn't this just a beginning? Mukuro was hating his life, and hate the Estraneo so much. The Mafia too, just why? Even if he's hating them so much, I doubt he have resolve to kill them.

If Estraneo and the Mafia do something to them and let them feel worse than they now, that's already enough for making his resolve to kill them strong.

I was in a deep thought thinking about it that I don't notice Marina that calling me.

"一hiru, Mahiru."

I snapped back to reality and glance at Marina that in beside me. I tilting my head in question, as she pointing at Mukuro.

He's seems bumped into someone and fall onto the ground. He clearly were displeased at that. I stood up and walk closer to him and look at the others that bumped to him.

I widened my eyes in what I see.

A spiky brown hair that defying gravity, a brown but there's a hint of orange eyes. He's wearing a simple orange parker and a simple jeans.

He stood up from the ground and apologized to Mukuro.

"I-I'm so sorry! Are you o-okay?"

There's no mistakes. That warm voice, and the voice that familiar to her that she always hear in daily lives.

"...Tsuna?"
