Fate x Konosuba:
Shirou died during his fight with Angelica, but he managed to save Miyu. Thus, he died satisfied, but then he opened his eye and in front of him stand a girl with blue hair claiming to be a Goddess who will reincarnate him into a new world.
She even claims that upon defeating the Demon King she will grant him one wish.
"Now! Hurry, and chose your Cheat, and be a hero that defeats the Demon King."
"Hero, huh. I no longer have the right to call myself that. I just do it to meet my precious family once more."
Setting:
I prefer the world is before Kazuma comes, but if you want to you can also choose after Kazuma takes Aqua away. As for Shirou cheat, you can give him whatever you see fit.
