Synopsis
A girl who became a demon lord at the end of her journey, and a saint girl bearing down on her with crushing emotions

Yurina, a girl who’d been accompanying the saint Teresia on her world-saving journey, hears Teresia’s anguished cry and realizes she’s been reincarnated into the world of a fantasy game.
The “ordinary” self she thought she was had awakened as the demon lord, fated to be struck down by the saint’s own hand.
But really, there’s no need to trouble the saint with that, is there?
And so she takes the demon sword in her own hands and drives it into her chest… but——?
