I Promise I'll Come Back.The news only reports the rocket launch failure in Tebwa, giving no updates as to whether or not Chernushka is safe. While other members of the Little Busters worry for Kudryavka, they read from the newspaper that entry into and departure from Tebwa is restricted in order to reduce risk of contamination from the exploded rocket engine. However, Kanata informs them that the Tebwan embassy has delivered a plane ticket to Kudryavka, granting her an opportunity to see Chernushka again. Kudryavka is conflicted about going back to Tebwa because she originally came to Japan in order to escape having dropped out of the Tebwan aviation school after six months. Initially, Kudryavka decides to stay and throws away all of her astronaut memorabilia, but Riki recovers the items and brings them back to her. Riki tells Kudryavka that she can just be herself in chasing her dream of outer space, even if she cannot become an astronaut. Kudryavka admits that she wanted to see Chernushka again and decides to go back to Tebwa. Before departing, Kudryavka leaves Strelka and Belka in the care of Rin and says a heartfelt goodbye to her friends.
