A Certain Scientific Railgun S

Mikoto Misaka returns to the ever-restless Academy City alongside her friends, following a string of unsettling rumors. What begins as routine investigation turns grim when Mikoto uncovers a clandestine project built on brutal experimentation—one that has already claimed the lives of thousands of espers. The victims aren’t strangers, either: they’re clones created from Mikoto herself.

Haunted by the idea that her own powers and identity are tied to the atrocities, Mikoto takes it upon herself to stop the operation. But the deeper she pushes into Academy City’s hidden machinery, the more formidable the opposition becomes, drawing her into a fight against espers whose strength rivals the city’s most dangerous secrets.
