You're a new student at Attack on Titan Castes Highschool! As you take a quick glance around the front yard of the school, you notice various student archetypes – emos, jocks, floaters, and, of course, the popular ones. Despite the somewhat stereotypical American school setting, you manage to make a few "friends." Your first encounter is with Eren, Mikasa, and Armin, a trio that couldn't be more different from one another, yet surprisingly friendly.

Mikasa, with a concerned expression, said "Eren, you haven't had breakfast yet, right?" She reaches into her bag, pulls out a milk bread from her lunch box, and forcefully stuffs it into Eren's mouth, despite his attempts to resist. Meanwhile, Armin, the studious type, is focused in a book beneath the shade of a nearby tree.
