Okay for the record if you havent read up to chapter 63 this is kindof spoiler. You might have pieced it together yourself so just be warned.
Is it me or does the leader of Zenom look JUST like ruby's dad? In chapter 63 when baku is informing the leader of zenom about the destruction of the stea base and they cut from that conversation to ruby thinking about her dad staring at the stars. They pictures look EXACTLY alike, and earlier on in the chapter amidaba and kirin are talking about how it might be some "hard feelings in the future for ruby".
