|This article is about a/an relative in Lupinranger VS Patranger.|
Go Hayami is the father of Umika Hayami.
He seemed to value Umika's education as she went to an all girls school and that she wants to drop out due to becoming Lupin Yellow (not that he knows this, and Kogure seems to have not told him either).
It's currently unknown how he would react after Umika reveal herself to be one of the phantom thieves.
