Kagero

陽炎

Kagero is the sole female warrior of the Koga Ninja sent to investigate the mysterious deaths in Shimota village caused by an even more mysterious plague. Her primary duty is serving as a "poison taster" for her master's food. It turns out that she is completely immune to poison because her blood itself is a deadly toxin. Merely touching her could be fatal.
Because of this, throughout her existence she has been thoroughly abused both mentally and physically by everyone except Hanza and a few other Koga Ninja. Tessai's attack upon her is just one of the degrading events of her life.
Due to the fact that she is a female warrior and her blood is poison, she has never been treated with any respect... merely as an expendable warrior. Because of this, she views herself as having no worth and is on a crusade to prove her value, while proclaiming her readiness (and sometimes willingness) to die.
Fortunately, Jubei treats her the way she deserves to be treated, as an invaluable friend, warrior, and a beautiful woman. As shown by her facial expression, his seemingly cold words opened her eyes to a world she had never seen before.
" I hate those who think so little of their own worth..."
This insight into Jubei's feelings is mutually reciprocated as Kagero falls for Jubei in a big way, and they are locked into a doomed love. For the first time in her life, she truly meant something to someone.
