Oreimo Vol. 3
Things get even weirder for Kyousuke and his vexing little sister Kirino-and all their friends! Crushes, misunderstandings, jealousy, meddling relatives, beautiful girls... looks like Kyousuke is going to have to ask for advice from his sister. She might just help him, but only if he does her a big favor in return, and if he can stop saying just the wrong thing at the wrong time!
