Gankis is an older member of Kennit's crew on the Marietta who can be talkative.
He likes to dote on Kennit and is one of the few men among the crew who aren't known to routinely embroider their own adventures. For this reason, Kennit takes him along with him to the Other's Island.
His uncle (the husband of his aunt) once went to the island to get his fortune told. That uncle is very religious and gives a lot of his money as well as two children to the order of Sa.
