If I marry a Japanese woman, this is how I would like to name our daughters. Fubuki for the oldest, Ayanami for the second oldest and Akatsuki for the youngest. If any of them has twin sisters I'd name them after the girls in the same subclass, i.e. if Ayanami has a twin the twin's name would be Shikinami and if Akatsuki is part of a quad I'd name her sisters after the 6th DesDiv.
