I originally intended for this to be longer and actually have a plot, but then I decided that it could stand on it's own pretty well too. If anyone's interested in seeing me add onto this, though, let me know!

No one understood what they had, what they shared. They were twins, the same, one. Always together from the very beginning. They should never be separated.
They were complete together.
Their parents didn't understand. This is a brutal world, they said, and you can't be dependent on others to survive. They gave each twin their own room, their own bed. To help them grow strong, apart from each other. They needed to be able to stand alone. But each morning, Kamui could be found in Subaru's bed, or Subaru in Kamui's.
They were stronger together.
Their teacher didn't understand. He was concerned about the twins developing the ability to study independently. It was obvious that they worked together; they always missed the same questions of misunderstood the same concepts. He started assigning projects, a different one for each brother. They needed to be able to work on their own. But every time, Kamui helped Subaru with his project, then Subaru helped Kamui with his.
They were smarter together.
Their classmates didn't understand. They thought it was strange how you could never catch one twin without the other. How when other boys were trading crude jokes, or describing their romantic escapades and conquests, Kamui and Subaru would stand apart, talking to each other without speaking. Creepy, they called it. Sometimes, a brave student would try to separate them, calling one into the conversation. They needed to be able to communicate with other people. But Kamui would look at Subaru and Subaru would look at Kamui, and they would return to each other.
They were satisfied together.
Seishiro didn't understand. He wanted Subaru, wanted to take Subaru, wanted to take Subaru away. Seishiro wanted to take Subaru away from Kamui, and nothing would stop him. He didn't care that tearing Subaru away from his twin would leave him hollow, half of who he was supposed to be. So he tried. He tried to break them apart. They were forced to leave, to run. Kamui with Subaru and Subaru with Kamui.
They were safer together.
They traveled across dimensions, never staying in one place long enough to become adjusted and fit in, but that hardly mattered. They were together.
Until.
Fûma didn't understand. He loved to tease Kamui and play with him, but he knew all the time that Kamui was capable of so much more than being Fûma's equal in battle. He mistook Kamui's feigned inability to best him as a desire to continue with the games between the two of them. He didn't realize that Kamui wouldn't beat him now, not because he didn't want to or didn't have the potential, but because he could not reach that potential. He could not. He was only half.
Half as strong.
Half as smart.
Half as satisfied.
Half as safe.
Incomplete.
