4

As Ruri and Sena's game is bashed on the internet, they decide to work harder towards making a better game. As Kyosuke prepares to go home, he receives a text from Kirino telling him to throw away her collection of eroge and anime goods. Kyosuke contacts Ayase, who reveals Kirino has not been in contact with her since she left either. Kyosuke then meets up with Ruri, who reveals her heartfelt thanks for helping her fit into school and encourages Kyosuke to fly to America to find the root of Kirino's problem, giving him a kiss on the cheek as he goes. Arriving in Los Angeles, Kyosuke meets up with Kirino at her track camp and plays eroge with her, cheering her up as she has not had time to play her collection. Kirino reveals that she had wanted to challenge herself and be more independent, saying she would not contact anyone until she managed to beat someone in a time trial, which she has not been able to do. Kyosuke tells Kirino that he is lonely without her and asks her to come back to Japan, which encourages Kirino to beat her elementary school roommate in a race and go home with him, reuniting with her friends and her anime.
