Student Council (SNK/AOT/EREMIN)

Eren Jaeger is the typical (and stereotypical) teen who shows no respect to school and its people. After discovering his sister's (Mikasa Ackerman) club in a different school from his, he vows to do whatever it takes to get in. Luckily, there was no fee for joining the Survey Corps. Eren is determined to become an official instead of being known for a new recruit. The club president, Armin Arlert, discovers that's Eren's only reason to become an official is to wear the 'cool' uniforms- but mostly the name badges- they had. With a little help with Eren's grades and driving reason to have joined, Eren then vows that he will focus on defeating the Titans. Him being an official is then reconsidered. He soon falls for Armin, which was before he even got to speak to him directly, giving him more reasons to do well in school.
