Maru went still when the hand reached up, not sure what was happening... until he was petted. And it was such a strange thing. He was used to it from certain people, but this was new. And nice... and without any conscious effort on his part, Maru slowly knelt down. Something he did for Madoka do that she didn't need to reach. It had become almost habit now. Because he did kind of like it. Maru had never thought he would. It was weird, right? He wasn't a cat. He was in human form so why would he let people pet him?

Except he did like it. And the gentle hand stroking his hair went a long way to calming him down.
