Kamui fiddled with the hem of his shirt as he stood outside his bedroom door listening in onto the conversation turned argument that was thrown haphazardly inside.

Closing his eyes, Kamui clenched his fists and bit his bottom lip. Subaru is, Subaru was a cool headed kid who could keep his mouth shut, essentially, he thought before he spoke, and he was never upset. At least not until now. Kamui honestly believed that he would be the one to explode, to disagree. He had never thought that whilst he was busy being distraught, Subaru's fury would be the one to escape him.

It was foreign, and it scared him.

"I promise you'd still be able to see each other!" their mother's voice explained, pleaded, whined.

Kamui could hear footsteps inside the bedroom, he could hear Subaru's voiceless agony that turned into a shrill cry.

That night, Kamui remembers holding his twin brother tight as they closed their eyes, each pretending that they were sleeping their tears away.

The next morning, Kamui stands helplessly beside their father and watches as their mother drags an unwilling Subaru off.

Kamui doesn't see or hear from the other for the next ten years.

It was the last day of secondary school when he finds someone sitting outside his front door, huddled together.

The person looks up and Kamui takes in a sharp breath, it was Subaru. He looked the same but clearly carried a different air to when he last saw him.

"Kamui."

Kamui blinked, gulped and then immediately bent down and pulled Subaru into a tight hug. Different to what he remembered, Subaru smelt like dirt and autumn leaves.

"Subaru, where have you been all this time?" Kamui rubbed against the other's soft black hair, the faint scent of honey reminded him of how they'd use to pour honey on top their pancakes every morning, he pulled back and looked at Subaru's face, "why didn't you contact me?"

"Kamui, I…",

Subaru's eyes were wide and started looking glossy, soon to be overfilling with tears. Kamui shook his head and pulled the other in for a hug again.

Kamui did not expect to be pushed away.

"Subaru?" Kamui's eyes widened at Subaru's expression, he could tell the other was frightened.

"Kamui, do you really not remember me?" Subaru asked with a trembling voice, his posture stiffened.

With raised eyebrows, Kamui looked at Subaru with confusion, "what do you mean? Of course I do, I remember all the times we watched the clouds roll by in the backyard, the times we threw paper planes from the balcony…"

"What about after mum took me away?" Subaru stressed, his hands clenched at his knees tightly.

"Well, we didn't keep in contact…"

Subaru closed his eyes and choked a sob, he shook his head and then buried it in his hands.

"Subaru? What's wrong?" Kamui lightly placed his hands on the other's shoulders.

"I'm sorry, Kamui, but I must."

"What?" Kamui tilted his head, trying to get a better look at this brother of his he hadn't seen in so long. But before he could even blink, Subaru's hand had reached to grab his shoulders, he briefly saw his brother's eye flash gold and felt a chill sink down his neck before he passed out.

"Another fail?"

Subaru closed his eyes and looked away from Kamui's lifeless body.

"Can we grow another one?"

Looking up at that voice, Subaru sighed as his parents continued to discuss.

"Subaru, we're going to clone Kamui again", the father stated, a comforting hand rested on Subaru's shoulder.

"Is he going to end up as a stranger again?" Subaru asked, letting his eyes wander across Kamui's 9th clone. He could feel his heart clench tightly.

The mother pressed her lips against Subaru's forehead and shook her head, "no, this time we'll make sure we can all live together happily. Forever."

Subaru swallowed, he could remember the metallic taste of Kamui's blood. Nodding Subaru sat with his back resting against the wall, his eyes tiredly watching as the cadaver remained still in the middle of their dimly lit room.
