After They Sacrificed Me, My Three Sisters Wept Bitterly Upon Olympus - Episodio 1

A person reveals that they are one of the three Fates and have volunteered their life as a sacrifice to banish a dark force threatening the world, wishing to repay their sisters. However, their presumed blood brother, Silas, arrives and coldly informs them they are an expendable outsider, unlike gods whose souls linger. As their sisters accuse them of harming Silas out of jealousy, they learn the sacrifice will erase them from existence completely. Resigned to being the only worthy offering, they accept their fate but secure three final days before vanishing forever.
