This is a world where Kiritsugu failed to find his salvation in Shirou. A world where Shirou became the Black Mud. A world where Shirou met the sisters of Sky Blue. (Shirou adopted by Aozaki sisters, Demi-Angra Mainyu Shirou, Dark Kiritsugu with Avalon)
Rewrite of Twice Inheritor. A boy with a dream meets a Wizard Marshal with a plan... and with swords that are not his, strength that is not his, and borrowed ideals, he will smite evil…knowing his broken hands do not deserve to hold anyone. It's a shame that the many girls he ends up saving disagree with him. Izuku x harem! Rated M for Blood, Gore, and eventual Citrus.
After the defeat of Goetia and his death at the hands of Chaldea, a few members of the Demon God Pillars escaped the crumbling Singularity and began planning their revenge. One, Vapula, ended in in Japan during the 1980s, in the small Misaki Town, starting a plan to get payback for their defeat.
