Four years ago...

In the Siberian Urals, there is an isolated orphanage - the Kokolia Orphanage. Pen ~ fun ~ pavilion www.biquge.info

In a small room in the orphanage, two young girls sit on the wooden floor, their petite bodies next to each other. The vase on the bedside table contains flowers that the two of them have picked together.

"Sister Bronya, what does the sea look like?" asked the girl with short dark blue shawl hair and a beautiful and delicate face, holding a fairy tale book in her hands, her blue eyes full of curiosity.

"Ciel hasn't seen the sea?" muttered the girl with two double brown ponytails like drill bits.

"No," Ciel closed her eyes and recalled, "I've been in the orphanage since I was sensible...", Ciel squinted her eyes and smiled gently like a rabbit, not showing any dissatisfaction with staying in the orphanage.

".......," the girl named Bronya pondered the words to describe the sea in slight silence.

"How can I describe it?..." Bronya was a little empty-headed. She scanned the room as if hoping to find something that would describe the sea, her hazel eyes rolling, and then she saw Ciel...

"The sea, it's like Ciel's eyes~" Bronya said with a smile as she looked at Ciel's clear blue eyes.

"By the way, Xi'er, it's almost summer. It's not as good as us..."Bronya said with a smile as she took Ciel's white and smooth hand. "―Let's go see the sea?" said Bronya with a smile.

"Well, yes!Sister Bronya~" The afternoon sun shone through the unobscured window, and the spring breeze gently blew a few strands of hair from a girl named Xi'er.

……………………………………….

"Sister Bronya, it's so dark here..." Bronya stood in the darkness, unable to see the road ahead. A familiar girlish voice sounded in her ear.

"Cial?!Is that you?!Ciel!" Bronya shouted the girl's name aloud, running through the endless darkness looking for the familiar figure.

"Sister Bronya, it's so dark and cold in the deep sea..."The voice of a young girl named Ciel came from the darkness again.

"Ciel!Where have you been?!Where have you been all four years?!" Bronya called out from the darkness.

"Sister Bronya~ Xi'er is so miserable, is Xi'er going to die?" Ciel didn't answer, as if talking to herself.

“... Ciel ...... Ahh

"What is this..."Bronya reached out and touched something that had tripped over her in the dark, and there was a warm, sticky touch from the palm of her hand, which was the human body. Bronya raised her hand and sniffed softly, the smell that had been etched into her bones since she was a child - the smell of blood. Bronya carried the man who smelled of blood into her arms and saw the faces of the dead in the darkness.

"Xi'er!!!!" she roared like a beast.

…………

"....huh!huh!~" In the room where the curtains blocked the sunlight and looked a little dim, a girl named Blonia suddenly sat up from the bed, gasping for air, and the sweat left on her back and forehead soaked Bronya's pajamas.

'Did you have a nightmare?' thought Bronya, looking down at her sweaty hands......

There were still two people lying on the big bed, Kiana and Mei Yi, they were still asleep at this time, and Kiana was holding Mei Yi's body and even buried her head in each other's chests, showing a happy smile.

Bronya jumped lightly from the bed, walked to the window and gently pulled back the black curtains, revealing the hazy and white sky and the slightly silent Sky City.

"Ciel... Where are you?" Bronya whispered. She had long lost her emotion, silently watching this collapsed world, and a crystal tear flowed from the corner of her eye. She gently wiped it away with her fingers and put the tears in her mouth.

"What about the smell of the sea......

"Sister Bronya~" At the bottom of the dark deep sea, it seems that someone is whispering.
