Sasha Izumi with her husband Mark Silverton, the father of Skye, Sara, Max and Kira Izumi, the reason Mark inherited the Izumi name instead of Sasha inheriting the Silverton when they got married, is because Sasha was heir/princess of the Izumi clan, so any man who wanted to marry her had to agree by Clan law to take the Izumi name if they wanted to marry her and she wants to marry them, Mark agreed to it and became Mark Izumi when he married Sasha.
