Dodgeball! Titan Junior High School

is the 3rd episode of the 1st season of the Attack on Titan: Junior High anime, produced by Production I.G.

Overview
Annie is unable to admit her love of cheeseburgers at lunchtime due to the derision Eren received after admitting to the same thing; due to this, she develops a grudge and vows to defeat him in the next day's dodgeball match. However, when the match rolls around, Eren is late, causing Mikasa to be unable to devote herself to the game. After multiple rounds, only two teams are left: one with Jean, Mikasa, Armin, Sasha, and Connie; the other with Annie, Reiner, Bertolt, Ymir, and Krista. At the last moment, however, Eren arrives, allowing Mikasa to give the game her all, battling to a tie with Annie while everyone else is eliminated. Annie finally admits the reason for her grudge to Eren and they make ammends, just as Connie finally figures out the rules and gets Annie out. Afterwards, Eren, Mikasa, Annie, and Armin have lunch together, and Mikasa becomes jealous when Eren and Annie start to bond over their mutual love of cheeseburgers.
