In a world where magic and science intertwine, Rayotte Steinberg, a solitary 'tactical sorcerist,' battles monstrous foes who were once human. These creatures transformed after abusing the forbidden power of 'magic.' Clad in a restrictive 'mold' to retain his humanity, Rayotte wields a destructive 'staff' that obliterates all in its path. Each spell he casts inches him closer to becoming a monster, yet abstaining means certain death. Amid relentless conflicts, he confronts a dark sin from his own history.
