Brad and Walburga Begin a Dangerous Journey
The story follows Brad Lester, once known as the strongest mage. After losing his young daughter, he disappears from society and scrapes by as a day laborer. His life shatters again when his wife is killed by an organization that claims to push “world peace.”
Brad sets out for revenge, but the person he finds is the group’s leader, Walburga, now trapped in the body of a little girl. She has lost her memories and has nowhere to go. Instead of ending it quickly, Brad makes a choice that changes the entire tone of the journey: he decides to restore her memory first.
From ancient magic research sites to strange towns and snowbound villages, the pair travels across the world together. The hook is sharp and easy to love: a lethal mage becomes an unwilling guardian, and the road keeps challenging what “enemy” really means.
Four-Week Release Kickoff and Reading Links
The comic is illustrated by Kazuhiro Hara（ハラカズヒロ）with the original story by Manimani Ononata（斧名田マニマニ）and composition by Yu Yagami（矢上 裕）. If you want the simplest way to follow the series, the best move is to keep the series page saved and check it whenever a new episode lands.
