There. Blood. The smell of it was both enough to turn his stomach and invite his appetite. He hated how he changed as soon as blood was spilled, but he needed it right now. He needed to be an unthinking, emotionless machine. Sano moved away and Okita ripped the pen out, his vision tunneling down to Sano and nothing else. Just his enemy, who wasn't really his enemy, just an unlucky guy in the wrong place at the wrong time. He would have felt sorry for him, if he'd been able to feel anything at the moment.

Blood dripped off the pen and onto the ground and Okita grit his teeth. He had to calm down, but-- No, he couldn't. He needed a release for his anger and it was easier to go and throw himself into some meaningless battle than to think about how he'd been abandoned again. Always left behind, always given away. He'd thought he'd have a place with the Shinsengumi forever, but even then, he knew they went off to their final battles without him. "What do you think happened?" Okita snapped, tightening his grip on the pen. He wouldn't pull his sword, he wouldn't kill Sano without a damn good reason. He had at least that much common sense left. Darting forward, Okita brought the pen around again, aiming for Sano's arm.
