Asuka of the Scarlet Sky Novel

Kashiwagi Yuuto's tedious existence ends abruptly in a devastating accident. Granted divine power by God—the ability to craft holy treasure tools—he's transported into a strange new world. There, he meets Asuka, an aspiring hero with scarlet-clad determination. As Captain of the Royal family's imperial guard, she commands the devotion of an entire kingdom. Yet this celebrated swordswoman conceals an untamed side, one drawn into secret indulgences beneath her heroic facade.
