A kid whose right hand erases every supernatural force on Earth finds a girl with 100,000 banned magic books downloaded into her brain, and neither of them can save the other the way it matters. The first arc is genuinely magnetic, the premise clicks, the world expands faster than you can process it, the character introductions land. After episode ten, the momentum collapses into filler-adjacent arcs that feel disconnected from what made you care in the first place.

Academy City runs on scientific advancement and superhuman abilities, but the wider world is one where magic is also real. Touma Kamijou is a high school student ranked at the lowest psychic level, yet his right hand holds the Imagine Breaker, a power that cancels any magical, psychic or divine ability, though it does nothing for his constant bad luck. One day he finds a young girl named Index hanging from his balcony railing. She is a nun from the Church of England whose mind holds every magical text the Church has pulled from circulation. A dangerous organization is hunting her, and Touma vows to defend her as he is drawn into a hidden world where science and magic collide, attracting the attention of powerful magicians and espers alike.
