第 7 集: 居民們為金星之旅做準備，而小光與星在健檢期間爭奪二奈的關注。

The Arakawa residents decide to do a physical checkup to prepare for their trip to Venus, and Kou and Hoshi end up trying to 'outsick' each other to get Nino's attention. Later, the girls spend a week in Sister's basement, though after six days everyone drops out except Nino. When it's the boys turn, Kou tries using P-ko's logbook to strike up a conversation, with embarrassing results. (Source: Wikipedia)
