She has even bitten him out of anger for trivial things that he has not even done, due to her tendency to jump to conclusions. It is a recurring gag for Index to bite Touma whenever he has inadvertently annoyed or irritated her in some way, occurring even in serious situations or in front of important persons, or out of anger for putting himself in serious danger and making her worry. He is often bitten by Index as punishment.
Index can be easily irritated especially when it comes to Touma, who usually ends up angering her in some way as a consequence of his own bad luck. She is a very cheerful and optimistic young girl, even after many years of having her memories erased annually. She is slightly ignorant and curious of modern technology, not knowing what a touchscreen was or how it worked until Hyouka Kazakiri showed her. She is noted by Touma to be a "gaikokujin" (foreigner), and it is likely that her nationality is English.ĭo I want beef or fish? Do I want beef or fish? Do I want beef or fish? Do I want beef or fish?ĭue to being raised in a church and having no memories of her life up until a year before she met Touma, Index is quite innocent and naive, often being elated by things that an adult or even people her age would find mundane. She still wears it, though safety pins are now needed to hold it together. It is an accurate replica of the Holy Shroud of Turin and offered Index ultimate protection from most attacks, however, it was destroyed by Touma's right hand. She is also often seen wearing her Walking Church, a white, modified nun's habit with gold highlights. She has thigh-length, silvery-white hair, and large green eyes. Although she looks like a little girl (and is even called one by Touma), she is actually 14 or 15 years old, making her as old as the 200cm (6 foot 7 ) tall Stiyl, and only one year younger than Touma. Index is small in stature, has a petite build, and, much to her chagrin, a flat chest.
