A miracle is finally happening: Major Himeko's finally getting married!

To whom, you ask? Well, that's YOU, you lucky commander!

tl;dr it's a happy ending AU where Himeko (barely) survived her final lesson and is now marrying you, a commander of undetermined gender who's been by her side throughout the long recovery process. Simple, sweet, and you've got a honeymoon waiting for you. CHEERS!
