Mioka's sister, nagisa, is in the middle of a conversation with the other girls in the dance club. She tells them that her little sister, nami, was tricked into taking a dangerous drug and sold herself to get more money to buy the drug. Mioka tells her that she can't find mio among the girls, but she does know that he's on his way back to school. She wants to know what's going on with saki and touma, but Mioka doesn't know where to look for him. She says that she's addicted to saki, and that she joined the sex club to get revenge on mio. She's happy now, and Mioka promises to be her pet.
