Weapon Story
"Poverty won't beat us. We'll finish this together."

Though not related by blood, they swore on the relationship as only an older brother and little sister could.

All they had was a single flintlock pistol.

Even in times of starvation, their pride prevented them from pawning off their most prized possession.

The pair slowly withered away until they finally collapsed. They had used up all of their strength, and just when it seemed they would keep their promise to each other, they realized the barrel was empty.

Though completely in vain, the older brother held his younger sister close as she pulled back on the trigger.

In that instant, the gun, seemingly acknowledging these prideful spirits, exploded with a brilliant light.
