So, I want to make a quick note on character relationships in roleplaying. It is absolutely vital that, in an RP, you are strong when RPing relationships between characters, unless your character is some android without emotion or something. Let me give you a quick example...

K2323 grinned, looking around the K Dome. How interesting, he noted. It seemed he'd been brought back.. For a battle? K2323 had not been here in years, his fighting tournament arena. He was here for a reason: To fight someone, whoever was here to fight him.

Hikaru stepped out of the shadows looking the same as ever, an expression of amusement upond her face. "Greetings brother dear, been a while hasn't it?" She laughed, mocking his death.

K2323 glanced upon Hikaru. His sister. She looked.. the same as always, a product of what the sages called 'immortality'. Honestly, that was not near as effective as real immortality, but real immortality? That was impossible.. "Hikaru, you look just as ugly as always," K2323 greeted.

"For a dead guy, you sure have some nerve." Hikaru muttered in response. "At least some of us are still alive."
As you can see, the two characters in this case are siblings, and have an active rivalry. The dialogue reflected that. They did not exchange greetings and talk about the weather. They were true to their personalities. That was absolutely clear by the dialogue, it was short and simple but strong.
Just a note.
