Tenten Koganei

The only sister out of the Tiger clan. She is the one who initially poisons Koshi, forcing him to come to their village to seek out the antidote. She is always wearing a fake smile, and is also the one who destroyed the Miyamoto clan from being the most powerful clan. She is secretly in love with Hanzo, though never reveals this in the series. She also shares a deep hatred for Iroha, who apparently "stole" Hanzo away from her.
