(凍空 こなゆき)
from Katanagatari
Konayuki is the last remaining member of the Itezora clan. She is immensely strong, but claims to be the weakest of her peers, and much weaker than the adults in her clan.
Katanagatari
The historical epic centers on Shichika Yasuri, the seventh generational head of the Kyotō-ryū school of martial arts in medieval Japan. He and his older sister Nanami live on an isolated island, until a military advisor named Togame tells him of the final 12 swords forged by a legendary swordsmith. At Togame's bidding, Shichika embarks on a journey to find all 12 of the swords.
