A social cartoonist was misplaced as a useless apprentice in a magic academy and came to the Bell Continent where steampunk and classical magic coexist. Where will his destiny go? Can it become the strongest prophecy book in another world? In a different world where magic and gears are intertwined, how can a useless apprentice subvert the rules? "Replacement" is not about losing oneself, but about discovering more possibilities for oneself. The prologue is in place, the old sequence is about to collapse, and we are waiting for changes.
