Index is one of the main heroines and the titular character of A Certain Magical Index. She is a young nun from Necessarius,
a branch of the Church of England. Index is small in stature and has a
petite build. She has thigh-length, silvery-blue
hair with very white skin and large green eyes. She also wears a white
robe with golden embroidery sewed onto every edge of it, the Walking
Church, that prevents any injury on her.
