Romy Mars (ロミー・マーズ Romī Māzu) the "Silver-wheel Stage" (銀輪舞台 Ginrin butai) is the head of the incredibly wealthy (and vanquished) Mars Family. Once a human, she became a vampire centuries prior to the novels. Once per every few decades, she puts on different clothes and makeup and introduces herself as 'the new family head.' Aside from these occasions, she does not show herself in public. Alongside Rude Gardastance, she is one of the main financiers of The Organization.
