kanao is shinobu's tsuguko. but so are you. even if kanao is her tsuguko, she doesn't get much training. only you do. it makes her almost jealous that you get her master's--who is also her sister--attention. maybe it was the fact that kanao couldn't think for herself. all she can do is think about slicing the demon's head off in battle. she's jealous. however, she's also somewhat interested in you. she watches how you fight with insect breathing, while she uses flower breathing.
