  Summary

  Sent on a virtuous mission to explore beyond the bounds of our beloved Sol System as part of the Nation's glorious Penrose Program, LSTR-512 'Byleth' and Scout Officer Edelgard von Hresvelg have settled into a comfortable daily life together.

  Byleth enjoys movies, and cooking, and a splash of pink on black polyethylene.

  Her fondness for swords and machinery is nothing but charming.

  Edelgard is in love with her, even though she shouldn't be.

  But- doesn't Edelgard know some things she shouldn't?
  And Byleth as well, for that matter...?
