A/N :

hachinonana : Aria is an OC.

ghostsmile96 : Damsel in distress is unmatched to Hibari, no?~

"What?" The boss of Varia glared at his right-hand man for disturbing him early in the morning.

"She left."

"Good riddance." Xanxus yawned, obviously not having an interest in the matter.

"She left this."

Xanxus looked at the sealed envelope with Aria's emblem on it that Squalo brought to him. He crumpled it to pieces and let his Ligre ate it. "Stupid trash."

Meanwhile, in his office, Tsuna rubbed his temple. His head felt hurt and spinning into parallel world after reading a very short letter from Aria.

Leave me be.

- Aria.

"There's so many people guarding this place and no one saw a thing?"

"There's no need to be surprise." Belphegor played with his knife. "If the princess didn't want to be found, she's not going to be found."

And the selfishness and arrogance of Varia never failed to made the entire Decimo's family facepalmed and wanted to kick them in the ass.

"She's one of you! Aren't you worried about her?!" Ryohei shouted so loud that Belphegor covered his ears and cringed at him.

"One of us?~ Ushishishishishi." Belphegor creepily laughed. "Don't be mistaken. Our relationship is not as chummy as you are. We're just bunch of killers who enjoyed killing others."

"Including Aria?"

Belphegor grinned. "Princess is a special case. But amongst us, if she decided to kill, it's not going to be pretty. She's scarier than that stupid boss of ours~"

Yamamoto gulped. Tsuna's eyes widen. Gokudera had this quesiness inside his stomach. Oh god. What could Aria possibly wanted to do now?

Aria was standing in a vast field of greeny grass where the breeze welcomed you by blowing on your face gently. The scent of grass mixed with the waterfall nearby gave a sense of refreshness than the usual blood scent she usually got tainted with.

In front of her was a sole memorial stone that had cracked alongside the time since it was first there.

"Alvise..."

Flashback

"You're okay?" Alvise asked during one of their short break before getting experimented with again.

Aria nodded. "There's less kids now."

Alvise didn't respond to that. Eventhough they were still too young, they had already understand how this world worked.

It's not kind to anyone, especially to the weak.

"Do you ever wish to not have this power?" Alvise softly whispered, scared if the guards hear him.

Aria looked at the ground, before returning her gaze at Alvise. "Sometimes. I could have a normal life like the kids outside. All my life I've been cursed at, chased out, and hunted every single minute like I'm some sort of monster, even by those called family. I don't choose to be born this way..."

Alvise gripped Aria's smaller palms tightly. "It's okay. I'm here. We don't need family as long as we have each other. We'll always be together."

Aria's gloomy face brightened up. "Promise?"

"Pinky promise!"

End flashback

But, Alvise broke their promise.

The day their captor decided to rebel against the world, the government had already caught wind of it. Thousan of armies rained down on them. The laboratories were burned down, every single life wax exterminated without a question asked and in a flash, everything was reduced to nothingness.

Flashback

Aria and Alvise were surrounded by armed men, not giving chances when their opponents were only two young kids.

"A-Alvise..." Aria held Alvise's back shirt tight. Her eyes were teary and her face was scared to death.

"I'll protect you, no matter what. It'll be fine..." Alvise's voice was shaky, but tried to remain calm for the sake of his friend. "We will get through this..."

"KILL THEM! DO NOT SPARE ANYONE!"

Aria was sobbing at dying Alvise. "I-I'll get help. Wait here!" Alvise pulled her close to him. "Al.."

"No use. I'm at my limit..."

The girl's tears streamed down faster. "No! No! No! You promised! What am I doing to do without you?!"

Alvise wiped her tears with his bloody hand. "Live on. Live so hard that death would love to see you exist. Live for me."

"Al..vise?"

Alvise chanted something in ancient language that's incomprehensible for young Aria to understand. A bright light was born in Alvise's palm.

"You'll need this. It's not much, but this is my parting gift. Happy birthday, Aria."

Aria's eyes widen. "You...remembered?"

Alvise gave a weak smile. "Yes. Because when I first saw you smiled, I never know that angel existed."

"...Alvise.."

"I love you." And his hand fell motionless on the zero ground.

"NOOOOOOOOO!" Her voice echoed through the universe.

End flashback

Aria let her tears rolled down her cheeks. She fainted by Alvise's side last she remembered. When she woke up, his remain was not there.

She looked for it up high and down low, every nook and cranny of this world. That was when she stumbled across Varia.

Her raw and unstable powers piqued Xanxus' interest. Under Varia's strict and harsh training, Aria had grown stronger. Strong enough that Varia silently recognized her strength and knew better than to mess with her.

Despite her nicknamed [V]aria which meant that she's the fifth strongest, there were speculations that she's still hiding more than what she had let shown.

Aria took in a deep breath. She clenched her fist hard. "I'm coming to get you, Alvise. This time, it'll be my turn to save you."
