Biology Club (Junior High Anime)

The Biology Club is an activity club at the Attack Junior High School.

Story
Hange boldly enters the Attack Junior High Scout Regiment Club showing off Titan fingernail clippings she found in the trash. Again, Eren asks for Levi, so Hange instructs him to throw a plastic bottle in the paper waste bin. He does so, and Levi rushes in with Armin's futon, smacking Eren in the head with his paper fan. He returns Armin's futon and repairs the hole. Levi then asks for verification if they would still like to join the club. Everyone backs each other up, aware of the risks they are taking. Levi approves all of them in, with a few who reluctantly admit that they are in other clubs already. Later she approaches Levi and tries to extort money out of them for lunch. When they ask her why she cannot afford her own, she shows them the two Titans she is keeping captive, forcing her to use up the biology club's budget as well as her allowance to feed them. Levi takes pity on her and gives her a bag of dog food to feed the Titans, which she then eats herself.

During the school's 104th festival, Hange has her two captured Titans in the room and begins her experiment by repeatedly tickling Sawney all over, and it tries to bite her as she comes closer to it. She continues tickling her Titans. Laughing at the face Beane is making, she tells Moblit to sketch its face.
