Iris is Sakura's younger sister, and a really scary heroine. Not only she is very overprotective of Sakura, she even goes as far as to kill for her sake. She's extremely hostile towards Kyuushiro, and whenever Kyuushiro approaches Sakura, her killing intent gets stronger. Well, don't mess with the loli assassin.
