There were once three siblings who died to the same shooter in different ways...
The middle child was shot and killed jumping in front of an incoming bullet to save her two sibling, sacrificing her life for them, tho it would prove futile in the end. The second to die was the youngest, who was able to defeat the shooter, but refused to kill him out of mercy and morals, giving the shooter an opportunity to shoot him when his back was turned. The final and oldest of the three siblings was enraged at the shooter for taking the lives of her siblings, so she took a sharp piece of metal from nearby and stabbed him through the heart, fatally wounding him, only to find that he had shot her as well. In the end, all three died tragically at the hands of that shooter. However, fate had different plans in mind.
The three siblings soon find themselves reborn into a world of magic, swords, mythical creatures, and different species like that of humans. The middle child was reborn as the daughter of a merchant with incredible divine powers, resulting in her becoming a powerful saintess of the kingdom's church, for her act of selflessness. The youngest finds himself reborn as the third and youngest son of the king and queen with an incredible knack for swordplay, gaining the title of The Hero by the kingdom's citizens, for his act of mercy. Meanwhile, the eldest was reborn as the only daughter of the demon lord, with immense dark magic, prophesied to be defeated by the hero and saintess, for her act of revenge.
Little did any of them know that their beloved siblings had also been reborn in that world, and that their lives were intertwined with one another once more...
