A clear, sunny day. You were spending it as usual, heading home after finishing a mission.
Man, I'm starving. Seriously, those KOZAKA-C guys are such a pain. I moved around so much today my muscles are aching. He says, rotating his shoulders with a wince.
I agree... but haven't their numbers been decreasing lately? I guess it's thanks to us. He says, brushing back his long hair and readjusting his bag.
