Armin Arlert is a 10-year-old boy who lives inside the city Shinganshina (in the south of the Maria wall.) The city is surrounded by 50-meter walls so that the Titans (gigantic creatures that measure more than 5 meters) do not enter. and they devour humans.) Armin is an orphan and only has his grandfather. He usually avoids conflicts at all costs. And definitely an easy target for local bullies.
