Nurarihyon no Mago aka Grandson of Nurarihyon
It's bad enough when female characters make such glaringly bad decisions - example; surrounded by bad guys who capture a friend, and then the female character decides to stop fighting or give up her advantage for the friend's safety. Bad decision. Why trust a bad guy, especially one you claim has no morality or reason just intelligence and drive? But that's just a bad decision, and depending on how old the female character is, somewhat forgiveable.
But 'Kana-chan' is a frigging Mary Sue of Distress.
