As a side note, why is Kirino imagining Manami as fucking with her glasses on? There are artistic implications to that which beg the inquirer to be told, "It's a heart-wreching porn pic. Shut the hell up and stop thinking so much."
Who hates Kirino? She's a selfish, egotistical, shallow glamour girl, who just happens to be a straight A student with a well-paying job as a model... Yet she's also a bisexual pedophile and withheld her otaku lifestyle for years.
I don't see how you can hate her, she is one of the best personified characters out of most fiction I've ever experienced, and she's not even the narrator. Not once do we hear what she's thinking, we instead can only see what she's thinking though her body language.
