Season 0 · Episode 23 — My Little Sister Can't Be This Cute
Kyosuke and Manami graduate from high school. After the graduation ceremony, Kirino arrives to pick Kyosuke up following the end of her middle school graduation, and both head out to meet Manami. In a park, Manami scolds them about their relationship. Manami and Kirino then get into a fist fight. Manami scolds them some more and then confesses her love for Kyosuke. Manami then punches Kyosuke and accepts his rejection. Later on, Kirino and Kyosuke have a pseudo-marriage at the church. They kiss, and then Kirino gives Kyosuke back the ring she was given before. It's revealed that Kirino's idea for their relationship was to be a couple until graduation and then go back to being normal siblings. In the epilogue Kyosuke and Kirino head to Akihabara for a meet-up with Saori and a new member. Kyosuke casually kisses Kirino on her cheek, much to her disgust.
