It wasn't that hard to cheer Chise up, the only words one would need to say were 'stupid!' or 'idiot!'. But Fai was a kind person and wouldn't ever call someone that(unless they were a certain bear).

"I know, but I wish I could do more. If only I was a bit stronger. There was this lady who knocked out all the zombies in the kitchen in a matter of seconds! She was really strong." The same could be said for Kurogane. "Mr. Kuro was with me and another boy last night. He really is a ninja! He managed to catch a knife that I threw at him when he asked for it. It was really cool."
