Glen Mackenzie

Glen Mackenzie (グレン・マッケンジー, ?) and Martha Mackenzie (マーサ・マッケンジー, ?) are an elderly Canadian couple who live in Japan. Glen is a 72 year old man, originally from Australia. Their son, daughter-in-law, and grandson were unable to adapt to Japan and have returned to Canada.
They provide lodgings for Waver Velvet (who has made them believe he is their grandson) and Rider.
Though near the end, despite Waver's spell being under his effect, Glen was able to figure out that Waver was not his grandson, by asking him a question that contradicted with the memories he had of his actual grandson, but was still happy to have him around and didn't mind if Waver continued to do so. After the Fourth Heaven's Feel , Glen and Martha gave Waver permission to stay in Japan with them for a while, it is implied that Glen is aware of Rider's death since Waver mentioned how both he and Rider were involved with a life threatening situation when both Glen and Waver were alone on the roof.
