Mary Godwin is the close sister of Shelley Godwin. Although she holds no true rank in the Kukai Foundation organization, Mary functions as Jr.'s second-in-command on board Durandal as well as the Chief of the Kukai Foundation's Strategy Division. Everyone in the Foundation respects her and values her opinions in spite of her unofficial affiliation. Mary is also fun loving and the life of the party within the Foundation. In fact, many members of the Kukai Foundation have initiated the "Mary & Shelley Fan Club", at the suggestion of Jr. himself. Mary is quite fond of Jr., although her true affection lies with Gaignun Kukai.
