One day before Nobuyuki and Rea's wedding, the women-only "Masaki Ladies' Assembly" gets together.
With her wedding to Nobuyuki, Rea will finally be able to become an official member.

Right after swearing her oath to the assembly, Rea's immediately asked about how her relationship with Nobuyuki began.
Meanwhile in space, left behind by everyone, Airi worked all night to finish her work and tries to get to earth,
but the transportation gate doesn't work and only spits out a recorded message from Washu.
Back when Nobuyuki-san 
was about to marry Kiyone,
،آنذاك عندما أوشك نوبويوكي-سان على الزّواج من كيوني
quand Nobuyuki s’est marié
avec Kiyone,
Quando Nobuyuki-san stava per sposare Kiyone,
Quando o Nobuyuki ia
se casar com a Kiyone,
Когда Нобуюки собирался
жениться на Киёнэ,
