I'm trying to explore Seimei and Soubi a little. I don't know that I did either of them justice, but I did what I could. Thanks for taking the time to read it.

I knew I shouldn't have brought it up, but I was worried about him. It's my job to worry about him, isn't it?

I stood in the hall for a moment or two and gathered up my courage. I knew it would start a fight if I said something, but I knew that he'd be upset if I let him stay awake all night, as well. I stepped into the small living room.

"Seimei, it's very late. What are you doing awake?" I asked.

My Sacrifice gave no indication that he had heard the inquiry. He sat as he had been sitting, game controller in hand, attention focused on the television screen. It was the only source of light in the room, and it threw the world beyond Seimei into complete darkness, even as it bathed him in its glow.

'Like the real world,' I thought. 'Seimei is the bright center, and everything else around him is nothing but shadow.'

I hazarded speaking again. "Seimei, you have school in the morning, don't you? You need your rest."

I saw Seimei bite the inside of his cheek lightly. I knew his temper was rising, but he refused to acknowledge that I was talking to him. I suppose he fancied himself busy.

"Seimei, please," I said. "It's nearly two in the morning."

I could almost feel Seimei snap. He stood and threw his game controller to the floor. The room instantly felt ten degrees cooler than it had a moment ago. His power, even at a time like this, was remarkable.

"Who are you to tell me what to do?" he shouted.

I swallowed my first response (Agatsuma Soubi), because I knew that it wasn't the answer he was looking for. "Your Fighter," I said. My voice seemed tight in my ears.

"That's right," Seimei said, and his voice was calmer already. "You're my Fighter. That means that of the two of us, I'm the only one with enough authority to give orders. Soubi, what do you mean by telling me what to do?"

I lifted my chin slightly, and Seimei narrowed his eyes. At length, I spoke. "To be fair, Seimei, I never actually gave you an order. I only mentioned-"

Seimei's hand connected solidly with my face, effectively cutting off the end of my sentence. Stars bloomed across my vision, he had hit me so hard. I clenched my jaw, but made no move to defend myself as Seimei struck me across the cheek again. The third time he hit me, my glasses clattered to the floor. The sound seemed to sober Seimei some. His hand dropped to his side.

"It's late, Soubi. I'm going to bed. Sleep on the couch."

I nodded, but said nothing. It didn't matter that this was my apartment, and that Seimei was taking my bed. It didn't matter that there was a guest bedroom with a perfectly good bed only a few feet away. What mattered was that I had been told to sleep on the couch.

I turned off the television, but I left the console on. There would be hell to pay if I caused Seimei to lose his progress. I lied down on the couch and tried not to think about how much my face ached. I gritted my teeth. I had had worse at Seimei's hands, that was certain. Still, my face stung, and my pride was hurt.

Nevertheless, I had gotten the result I was after. Seimei was safely in bed, and would no doubt be asleep in minutes. I turned to my side and smiled. It felt good to win a fight every now and then.
