Title: Rescue Me

Premise: A female OC, named Midori, who moves to Namimori at the age of 12, and basically takes on the role of Tsuna's older sibling despite her own family's troubles.

Rating: T (for mentions of death)

It was yet another day in the life. We had just moved to a place called Namimori, Japan, and while my dad was off at work, my sister had just come home from getting a haircut that had sparked a shouting match with my mom. For an eight-year-old, my sister was quite the hot-headed and rebellious child. I sighed, unable to take the ridiculously loud high-pitched voices anymore and quickly grabbed my bag, my shoes, and headed out the door. I sprinted the first few blocks away from the house.

I had an extremely dysfunctional family.

Ever since my younger brother had died in snowboarding accident, my dad had become withdrawn, drowning himself in work. My sister had acted out. My mother had random mood swings. And I had been stuck in the middle, trying to mediate. I really missed my brother. You see, my mother had been somewhat of a Tiger Mom, telling us to do our best in school, do our piano practice, the stereotypical Asian mom, though Dad was Caucasian, not that I was entirely sure what kind of ancestry he had. Anyway, Mom hadn't wanted to come to Japan, but my dad and my sister had insisted, and they had managed to persuade Mom.

And so, here I was, wandering around the streets of Namimori. Tomorrow, I would be starting my online schooling. I was 12, but I was doing high-school level courses. And I was trying to improve my Japanese. And so, as I was walking around, I was met with the sight of a small boy running in fear from a small dog. A very small dog, like, smaller than a Chihuahua. And then the boy tripped, and he was scrabbling to get away from the dog. I sighed and decided to help out, picking up the boy and grabbing the dog's leash. I had just nearly finished my growth spurt and stood at an impressive 5'8", overshadowing my mom's 5'2". And I was even with my dad's height. It just made me wonder where I had gotten the tall genes from. I had my mom's Asian looks, though with my dad's coloring, meaning that I had nicely tanned skin, blonde hair, and green eyes. My brother had had Dad's Caucasian looks, though with black hair and brown eyes, like my sister. Actually, my sister looked the most Asian, almost like my mom's mini-clone or something.

But anyway, this boy that I held really was small. I just carried him over to a nearby bench and set him on it, tying the dog's leash around a lamppost, and then I took off my bag and dug out the various first-aid supplies that I had and started cleaning the boy up. I also gave him some baby wipes to wipe his face with. Really, the benefits of being an eldest child. I had taken care of my baby sister when I was four, having helped feed her, change her diapers, bathe her, change her clothes, everything. And my brother had been quite the klutz, and I had always been fixing him up. And he had been a shorty.

"T-thank you, nii-san."

I blinked a bit. 'Nii-san'? Wasn't that older brother?

"Nee-san," I corrected. "I'm a girl." The boy looked so horrified that I quickly said, "But you can call me nii-san if you want. Midori-nii-san. Or nii-chan." Yup, I had chosen to change my name when I came to Japan, because Viridisabelle was ridiculous, even in English. I'd decided to go with the simple Midori. "And what's your name?"

"Sawada Tsunayoshi," he managed to stutter out.

"Well, Sawada Tsunayoshi-kun, do you think you can help me take the puppy back to his home?" And so we set off, with me holding the puppy and the little boy walking beside me.

I had my own laptop to do my online classes on, so, the next morning, I got up early, packed my backpack, and then headed out to go walk my new friend to school. My sister had to stay at home, since my mom didn't trust her not to fool around on the internet instead of studying. After I had walked Tsuna to his school, I headed over to a library, where I used the free wi-fi to do some of my classes. Then, I went to a cafe where I had lunch, then proceeded to do the rest of the day's lessons there, using their free wi-fi. And then I went back to the school to walk Tsuna home. Tsuna's little yearmates all looked at me in a bit of awe at my height.

And so, it became a daily routine. I would accompany the nine-year-old to and from school. And sometimes, I'd bring my sister along. And we were happy. And so life went on, and I graduated high school. I was sixteen, and I would be doing an online college due to financial issues. Both my parents had passed away when I was 14, my dad from overworking himself, my mom from suicide. Although I got legal custody of my sister, Sawada Nana deemed herself our adoptive mother. My sister was extremely bitter about everything, and she lashed out at me. I got a couple part-time jobs, and I was trying my best to support the both of us. She was going to start at Namimori Middle as a first-year with Tsuna. We lived in a tiny one-bedroom house, and I let my sister have the bedroom. And she'd always scream, yell, and insult me about me being too boyish or something. Or she'd ignore me. But I still tried to support her. She'd say that I should have died instead of our dad, our mom, our brother. She'd be perfectly civil to everyone else. I was just as lost as she was. And I began to doubt myself.

And then my sister got involved in a gang. And I wasn't around enough to see it, so I was devastated when I found out that she was in a hospital. I hadn't known anything was wrong, seeing as how she had gotten happier, and I thought she had made friends. But no, she was now in a coma in the hospital, and I blamed myself.

I was sitting next to my sister's bed, trying to do some of my homework. And then, I jumped when I heard a voice behind me.

"Do you want revenge?"

I turned to find the baby, Reborn, Tsuna's small tutor, standing behind me.

I laughed, a truly bitter and ugly sound, even to my own ears. "Revenge? On myself? Oh, trust me, I would if I could."

"And if it hadn't been your fault? Would you still want revenge?"

"No. Revenge isn't something I'm capable of."

"She may never wake up."

"I hope that isn't the case. Because I've already lost too much to self-destructive tendencies."

"Reborn, I'm worried about Midori-nii. It feels like she's dying instead of her sister. Even Mom noticed, and she usually doesn't notice much- Ow!"

"Respect your elders, Dame-Tsuna."

But Reborn was worried as well. Because Angelo Midori, when had first met her, had had a Sky Flame stronger than any he had even felt, including Luce, even though it had been locked behind stronger seals than those found on Tsunayoshi. And now, that flame was gaining a dark and potent shadow. If Angelo Midori's will to live broke, then the backlash of her flame dying could be catastrophic. And if her resolve broke, then she could become twisted and just as horrifiying as the Vindice, possibly even more.

And a couple weeks later, my sister died. She had lost her will to live, it seemed. She flatlined, and I had practically flown to the hospital with how fast I was running. My sister had left. When I cried myself to sleep, she visited me in a dream, saying that it hadn't been my fault, and she was sorry for having lashed out at me. I didn't blame her. And so I organized my last family member's funeral.

Whew, poor Midori. And no, she's not an SI-OC. She's just really smart and mature for her age. ~VM
