Magic Maker: How to Make Magic in Another World

マジック・メイカー ～異世界魔法の作り方～

Shion, a man reborn as a child in a fantasy world, arrives devastated to find that magic does not exist here either. When he witnesses an unexplained phenomenon at a lake with his older sister Marie, he devotes himself to building a magical system from nothing — no grimoires, no inherited power, no game-like framework to follow. Marie, who narrates most of the story, watches her younger brother pour himself into research she barely understands, never knowing he carries memories of another life.
