Send a private quack!
If he was just going to appear and talk to BladeVash anyway, why the hell did he carve a message on the freakin’ gun? This guy is Kaze, the main character of that dumb Final Fantasy anime. His job, according to Wikipedia, is to have amnesia and wander around killing stuff with his gun-arm. He and BladeVash are sure to be instant friends! Also, he’s dead, I guess.
BladeVash’s Dad seems to have known Kaze. Which is weird, him being a wolf and all.
