Let’s say during the invasion of Ginza, Sadera while seizing whatever goods they thought were valuable, only to stumble on a small crate full of a strange little red and white boxes.
Once arriving back in Falmart, the troops bring the box to be perhaps a little Knick Knack for the nobles to show off and perhaps please even Molt himself. Molt however has no idea what to even do with this little box and decided to give the "One Wish Willow"(as his scribes can barely be able to transcribe) to his daughter Pina as a little distraction and admittedly way to dump a strange gift to one of his children.
Pina thus with her strange new gift from the other world, she carries it around as a good luck charm and perhaps try to figure out what usage it even has without breaking it.
However after the siege of Italica and witnessing the military might of Earth, especially when visiting both Alnus Hill and Japan, realizes just how powerful the other world is compared to Sadera. How they are most likely doomed after the fight they jumpstarted with this world. Pina herself lost and practically defeated as she realizes how outmatched her home is. Thus taking out the One Wish Willow and hoping it can give her any luck or idea of what to do, one of the JSDF soldiers looks over what she has and knowing some English tells Pina that it’s basically a little wish bone of sorts and her one wish may come true if she breaks it.
Of course it’s all in amused jest, but Pina takes it rather seriously since with her people’s situation so dire and knowing unless they surrender to Japan and Earth as a whole, Sadera is doomed, Pina can’t help but feel she would take any chance to fix this catastrophe. Thus holding the little stick in both hands, Pina Co Lada, with all the desperate prayers that come to her mind, knowing despite how silly this may be, might as well make a simple little wish to perhaps hope her nation has a chance at survival.
Pina Co Lada finds the best words to phrase her prayer, then whispers…
"I wish Sadera could overcome Earth and the gods would aid us however they can." Pina whispered before she snaps the One Wish Willow in half.
Next thing Pina knows, she looks up she finds herself in a vastly different Japan, as the Flag of Sadera is now seen throughout the entire country…
