Reincarnated as a Hero, but He Marries the World-Ending Witches Instead of Slaying Them!

What the story is about

After completing a dating-focused run of a grim fantasy game, beta tester Byron awakens in its world with his memories and a chance to approach the five world-ending witches differently. He reunites with Anne, a silver-haired witch with immense shadow magic, and uses game-like systems and his knowledge of the story to grow stronger, protect her, and pursue a path to save the witches rather than kill them.
