Out of all the Oreimo girls I like Kousaka Kirino the best, Shes my favourite.
Ive always been firmly entrenched in the Kousaka Kirino camp from the get go.
Quite a lot of people on the interwebz seem to like talking smack about Kirino for some reason (Which ive listened to but never agreed with) Saying shes a 'bad girl' and worse... Some people are very nasty towards Kirino but I can really sympathise with her!
I just really like her character and think that shes a good girl. I would definately like to be her Aniki. (I have a sister IRL and can tell that Kirinos a nice sister too) :)
I like Kuroneko too TBH, In fact all the girls in Oreimo are nice but Kirino just has that X factor, That special something that shoots an arrow through my heart.
