榛原 永久

The head maid from Haibara family, who have served the Hinomori family for generations.

Her husband is an adopted son-in-law who works outside the estate, so they're estranged, meeting only about once a year.

She's usually a kind, capable woman who takes good care of others, but for some reason, despite being married, she harbors wicked, indecent feelings toward Masaaki and tries to seduce him.

She is in her late 30s.
