Fics like Before it's too late -English version

In an alternate timeline, a young Giyuu Tomioka is sent to a forgotten village to eliminate a demon that has been hunting in the region. Unbeknownst to him, this demon is the same one that would later turn Shizu—Sanemi's mother— into a demon. By stopping the demon, Giyuu changes the fate of the Shinazugawa family. In gratitude, Shizu invites him into her home, unaware that this small gesture will save many lives... and leave a mark on the heart of the future Wind Pillar.
