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.
All you'll be doing is drinking to the bride!
!كلّ ما ستفعلينه هو الشّرب
Ihr trinkt doch eh nur auf das Brautpaar!
Solo van a beber
y a chismear sobre los novios.
Solo vais a beber
y a cotillear sobre los novios.
Pourquoi ?
Tu n’y vas que pour boire !
Tanto non farai altro che bere 
alla salute della novella sposa!
Tudo que você vai fazer é
beber com a recém-casada!
Да ты просто на девичник едешь!
