Sekai o Yaita Majou ga Warau

On that day when the witches burned the kingdom to the ground, Abel, a boy who had lived a poor but happy life, lost his family and was about to be killed himself — when Noah, a beautiful witch scorned by others as “Anonymous," saved his life. Nine years later, Abel, now nineteen, has survived with single-minded determination. As he faces mortal danger in the wilderness, Noah — still looking as youthful as she did that day— appears before him once more.
