Wandmaker of the Ruined World

Oori Kenshi is a man who has lived his life solely by his dexterity. Even after civilization collapsed, that didn't change. One day, a magical meteor shower rained down on Earth and stole all its electricity. The advanced society, which had been sustained by electricity, crumbled in an instant.

Amid a world plunged into unprecedented chaos, Oori simply took his time, carving one of the meteors and crafting a magic wand. That's right. Humanity lost electricity, but in its place, they gained magic. In a collapsed world where electronic devices no longer function, Oori's dexterity, capable of craftsmanship on par with precision machinery, may become the key to saving the world.
