Overview
When Eren and his friends displease the upperclassmen, they are stuck with cleaning duty. Levi decides to teach them a lesson, challenging them to a contest in the Sports Day games in which the losing grade must clean the Titan's building. The next day, Sasha begins by losing the bread eating race to Hange when the latter uses her captive Titan, Sawney, to win. Jean also loses his game despite using the Omni-directional gear to cheat. The class begins to despair their chances of winning when Mikasa proposes a way to get ahead: defeat the upperclassmen in the shoulder wars match. They almost win, but are defeated by Levi. Hange then floods the entire field with confetti. As Eren and his classmates grumble about having to clean the field, they are joined by Rico and the other upperclassmen, who agree to help them.
