Index (Toaru Majutsu No Index) Rule 34

Index Librorum Prohibitorum is the central heroine of the Toaru Majutsu no Index series, a nun belonging to the magical organization Necessarius. She carries within her memory a vast library of forbidden grimoires, a burden that defines much of her role in the story. She is recognizable by her thigh-length light grey hair, green eyes, and her white nun's habit known as the Walking Church, a garment now held together with safety pins after being damaged. In personality she is cheerful, direct, and often hungry, with a strong attachment to Kamijou Touma. Fan artists frequently depict her in her signature white outfit, sometimes with the damaged details, and often place her alongside Touma or the cat Sphinx. Her long hair and expressive face are common focal points, and her close relationship with Touma makes her a popular subject for romantic or comedic fan works.
