And with that, Jean's goal is doomed. He plans to cover up everything until Eren comes. Over the corner, Keith Sadies overhears the case of Eren's absence. Terrifying, not until Mikasa breaks the terror-stricken beings by reasoning out that Eren went to the bathroom and the commotion is caused by Sasha's fart. Keith tells Sasha she should learn to control herself, as Sasha churns Mikasa demanding for a reason. Mikasa just shoves a bread into her mouth, much to Sasha's delight.

The group complies as Annie watches them from afar.

Hannes throws the ball into the air as Marco and an opponent tries to snatch it away. Unluckily for Marco, the opposite team got the attack first.

As everyone continues on with the match, Armin spots Sasha, slurping from a bowl of ramen. Sasha reasons out that it is better to eat it or else it will get cold and turns into a complete waste. The argument continues up until Armin warns Sasha of an incoming attack. The ball advances to her, but Sasha flawlessly avoids it, with the ramen still on hand. As she consequently dodges the incoming attacks, Armin acknowledges Sasha's focus when it comes to eating. All the while, Jean grumbles about having anyone decent to play in the team and then Mikasa comes to mind. The opponent launches the ball at Mikasa as Jean boasts that it does not have any chances on landing on her. The ball hits her and Mikasa is down. Armin reasons out to a dumbfounded Jean that whenever Mikasa is away from Eren in a specific long time, her stats decreases to 30% of her full capabilities. Surrounded by a gloomy aura, Mikasa turns into a state of despair, saying lines of how cruel the world is. Jean goes into confusion as to what kind of students this school embody. Throughout the struggles of the first match, Jean and his team manages to win. Mikasa curls herself up in Armin's futon, muttering words about the world's cruelty, again.

Before Annie takes to notice, her teammates are passing their Mozuku lunches to her. Much to her irritation, she orders them to eat it. In the meantime, Jean is prepared to be a Titan's meal else said, surrendering. Hastily, Armin thinks of a plan. Veiled with a wig, Jean pretends to be Eren.

Mikasa reappears with the ball in hand, asking Annie if she could teach her, too. Jean and the others start to bet food on whoever wins. Mikasa storms her way to Annie. She charges the ball and Annie prepares for a smash, out of nowhere, Eren gets up. With a single strike, he is sandwiched between the ball and Annie's foot, too much force sends Eren flying into the air; only to land on his back.

The students applaud as to what it seems a forming friendship between the rivals has set. But then out of nowhere, the ball lands on Annie's head much to everybody's confusion. It appears from the corner that Conny finally understands the rules of dodgeball. Annie is out and the game ends.
