An ancient prophecy has been foretold in the Kingdom of Silica. The prophecy states that in a time of great need, four heroes will arise. When Baingana-Kerejya begins ramping up hostility, the fate of village girl, Euthalia, and the demi-human knight, Elias, become intertwined in the fulfillment of this prophecy.
Started as a Tate no Yuusha (Rising of the Shield Hero) derivative work but has morphed into an original work heavily inspired by TnY.
