50 free A Certain Magical Index trivia questions with answers — trivia quiz, new questions added Oct 2026.
A Certain Magical Index began as a light novel series in 2004 and grew into one of anime's largest shared worlds, with three television seasons, a film and a shelf of spin-offs. Its hook is a collision: a city of students trained to develop psychic powers, and a hidden world of churches and sorcerers who work by very different rules. This quiz covers both sides of that world. Expect questions on Toma Kamijo and his unlucky right hand, the nun Index, Mikoto Misaka and the other top-ranked espers, the villains and allies of the major story arcs, and the people who made the novels and the anime, from the studio to the voice cast and theme songs. It is written for fans of the anime and readers of the novels alike. The opening questions suit anyone who has watched the first season, later ones reach into the third season, the film and the Railgun spin-off, and every answer comes with a short explanation.
