Don Wei

Eva's father and owner of Wei Racing, a successful Earth corporation that manufactures vehicles and sponsors races. Uptight and arrogant with an openly hostile view towards female pilots, he often hides his true feelings through formalities, as well as pride. When his daughter finds him, not only does he not recognize her — he even mistakes her for a boy at first. The death of his wife and the following separation from his daughter shaped him into the uptight man he seems to be. Due to several events while on Ōban, he finally discovers that Molly is his daughter.

Afterwards, he becomes very concerned for Molly's safety due to the increasing danger of the grand finals — even attempting to withdraw the team from the competition to prevent her from racing. Near the end of the series, he reveals to her that he knows she's his daughter, and didn't want what happened to his wife to happen to her.
