She is a member of New Light and was introduced in Volume 17. Lessar is a member of New Light with black hair and a dragon-like tail accessory which allows her to keep her balance when jumping because she can jump very high, but is also afraid of heights, as shown when she had no problems jumping to the top of a building but then hesitated to jump back down. She is the kind of girl who doesn't know how to keep a low profile. Lessar has so far made the most aggressive attempts at seducing Touma out of all the girls interested in him, and doesn't try to hide it. She once made a move on Touma while in a enclosed space in Russia but it is not shown what happened. After her clothes got wet from the snow and her bra could be seen through her top, instead of being embarrassed, Lessar is more annoyed that her 'secret weapon' to seduce Touma has been wasted after all of her preparation.
A Certain Magical Index
Academy City, Japan, is at the forefront of science. Besides being 30 years ahead of the world technologically, more than three-fourths of this peculiar city's population consists of students developing their psychic abilities as espers in various institutions. Among these students is Touma Kamijou, a high school boy with the lowest psychic rank of zero, but with a mysterious power no scientist can understand: "Imagine Breaker," which allows him to negate other supernatural abilities. This, however, doesn't affect Kamijou's life in the least as he plays his role as a regular teenager; that is, until he meets the strange Index Librorum Prohibitorum, a young girl who has memorized the entire forbidden grimoires, and now a dangerous organization is hunting Index down. With several magicians looking to harm the girl, Kamijou will defend his new companion at all costs as he discovers a strange new realm of the supernatural.
