Ethan
"Why hello there. Who might you be?"
A female voice caught me off guard and I turned my attention from a white rose I was admiring to look at her. Long lashes rimmed ocean blue eyes. She had long curly silver hair. Her style was a bit provocative.
I raised an eyebrow, walking to face her. She was shorter than me. She had a coy smile played on her lips as I approached the fence separating us.
"I think the better question is, who might you be?" I responded, but then my grin widened at the thought of having someone to talk to. So I replied, "I might be called Ethan. Or I might not be. Though I'm almost certain that I am."

(Sorry there's not much here. DNA, I'm a little brain dead right now. I hope you can turn this out.)

BrokenTear
"Catch me if you can~" Yuki sang after turning the tables on me. She had spun me around literally. I was now facing the door as Yuki took off into the forbidden room.
I felt myself lose my breath. What evil things lurk in this room were not to be messed with. Who know what they'd do if disturbed.
I followed quickly to find her frozen in place. I kept running to her though it felt like I was getting no where. Like I was running in place. Disorientated, I lost my balance. The world was saying side to side. I felt nauseous. My jaw slammed against the hard concrete floor. My chest felt heavy as I struggled to keep my breathing calm. Though it was getting shallower and shallower by the moment.
I watched helplessly as she appeared to be getting farther away. I soon realized that my vision was going blurry. I felt something cold crawl up my body.
"Yuki!" I shouted but it faded like a whisper. The cold feeling stung me as it enveloped me. I was shaking involuntarily but it was my only movement.
Engulfed in some strange sensation, I felt like I was drowning. Just trying to keep my head above the water after swallowing knives. My heart was pounding but I felt my blood rushing out of my body.
Giving up, I felt like there was so escape.

(Here you go Ally. Just make up something that'a attacking BrokenTear. It can be the feelings or really anything honestly haha XD)

Forever
As Setsuna asked about my mask, he made himself comfortable which seemed to be something I couldn't bring myself to do. I blinked for a moment, trying to unscramble the words jumbled in my head about my mask.
"It's something that happened to me when..." I wanted to say, 'when I died', but I never really did die though that's what it felt like. In my mind I always referred to that moment as my death. I remembered the tall trees looming over me with their mocking spindly branches. Reminding me that even the 'safe' haven that was my natural home was dangerous. I shuddered at the thought before continuing.
"... When BrokenTear found me, there was some sort of drug in me. There still is. Which makes me unable to breathe in normal air." I paused, my eyes flickered around the room nerously.
"The cure is unknown still, because the poison is fairly new to the world." I explained, "I... I spend a lot of time looking for cures but I've yet to find anything that works. Without the mask, I end up on the verge of death."
The memory of nearly suffocating myself lingered in my head for a bit. I remembered my breath escaping me. My sight going cloudy as my hearing became void. My heart had skipped and pounded so fast and roughly against my chest, trying to revive me. I shook the thought.
"I wish I could breathe again..." I thought aloud but then remembered Setsuna was still here, listening and I blushed.
"So that's what happened..." I bit my lip under my mask.

(Sorry that I don't post as fast as I should. >.<)
