Yuu-kun, Onee-chan to Aso Ba Nai??

*Vol.1:* Yuu spent several years wishing he had an older sibling, and he thought he got his wish when his mother married a man with a daughter. Dreams don’t always come true, though. His sister Nagisa is an absolute terror, and he starts to believe that’s just how older girls are. Nagisa’s friends are about to change his mind, though! --- *Vol.2:* Yuu has just had a wild time with his stepsister Nagisa’s two best friends, but Nagisa is upset that he thinks they’re nicer than her just because they had sex with him. She’s going to prove that she can be every bit as nice if she chooses to be.
