Miku was worried. She didn't like seeing her girlfriend in that sort of condition, but while something was obviously wrong, Zashi wasn't telling her anything. And she couldn't help if she didn't know what was going on.
So, she went searching. Every time she ran into someone, she asked if they knew what was going on with Zashi. Even if they asked who she was, she'd describe her and see if they recognized her from that.
She had to find out what was going on.
She didn't want to see someone she loved suffer so much. ]
