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.
We need to find out the reason 
for Rea coming here.
