Keep Working Hard.The Little Busters start a teamwork exercise for their morning practice. Later, Kudryavka decides to apply for the national practical exam in school, and the other members of the Little Busters agree to tutor her, especially in her weakest subject of English. Komari covers English, Mio covers math and physics and Masato covers Japanese history. When classmates Takamiya, Katsusawa and Yamazaki deride Kudryavka while in the cafeteria, Yuiko quickly scares them away. In the library, Kudryavka tells Riki, Masato and Yuiko that her grandfather raised her and took her on many travels, including a small island nation called Tebwa in Southeast Asia where she was born. Kanata comes by to give Kudryavka back her book on the many-worlds interpretation, one of many books she reads for international exams as a hobby. On the day of the national practical exam, Kudryavka accidentally fills in the wrong bubbles on her test, having to take a remedial class as a result. Kudryavka feels bad about failing after her friends helped her study so much, but the others members of the Little Busters show up in the remedial class to show her that she is not alone.
