Ore no Imouto ga Konnani Kawaii Wake ga Nai.

Synopsis

While Kirino organizes things with school and friends following her return from America, Kyosuke grows concerned that she might start ignoring him again due to the way he forced her to come back. At the same time, he struggles to find the meaning behind the kiss Ruri gave him when he went to retrieve her. Later, Kirino once again calls upon Kyosuke for life consultation, having him take her to Akihabara to watch a trailer for the next Meruru season before engaging in a long-missed shopping expedition she spent the entire night planning. As thanks for his help, and to celebrate a year of life consultation, Kirino gives one of her eroge purchases to Kyosuke to play.
