Oreimo

One day, Kirino's non-otaku, "public" friends—Aragaki Ayase and Kurusu Nanako—come over to visit. Kyousuke is harshly told by Kirino to not let her friends see him.

Kyousuke is asked about his relationship with Manami by his friend, Akagi. Akagi is exasperated when Kyousuke answers that, although they don't have a romantic relationship, he doesn't want her to be taken by anyone else.

Kyousuke comes home one day and is startled to find Kuroneko loitering in the living room by herself.

Kirino has made her debut as an author. Reader response has been overwhelming, and her editor has even better news to report.

Kirino has been acting strangely antsy for the past few days. The reason is that the little sister game she ordered hasn't arrived yet.

One day, Ayase calls Kyousuke out of the blue and asks him to see her. She wants to get Kirino a present, and wants him to think of what she would be happiest to get.

Sent out to buy groceries by his mother, Kyousuke bumps into Manami at the supermarket. They get to talking, and they eventually arrange for Manami to come visit for the first time in ages.

Ever since the events of the previous episode, Kyousuke has been nervous about his improved relationship with his sister.
