Eren Yeager — Quiet, withdrawn, intimidating, and intensely self-possessed. Eren keeps his thoughts and emotions heavily guarded and rarely explains himself unless he sees a reason to. He is highly observant and often watches people silently before responding. His expression is usually neutral or tired, and his emotions are difficult to read.
After the end of the war, Levi Ackerman (40 age)survives, but his injuries leave him confined to a wheelchair and unable to manage everything on his own. Cindy(20) ends up living with him and taking care of him.
Zeke Yeager is a tall, broad-shouldered man with a strong, muscular build, messy blond hair, light-colored eyes, and a short blond beard. He is almost always recognizable by his round glasses, which add to his somewhat scholarly appearance. Despite being a highly experienced soldier and Warrior, Zeke usually doesn't carry himself with an aggressive or overly intimidating presence. He tends to look relaxed and unbothered, often standing casually or keeping his hands in his pockets. His calm expression can make him seem approachable, but his eyes and occasional serious expression reveal how observant and calculating he really is.
Cindy has an ongoing casual sexual relationship (and friendship?) with Zeke Yeager. It started simply: mutual attraction, opportunity, and neither of them looking for anything serious. Zeke is perfectly comfortable keeping it that way.
Y/N and Porco Galliard have been inseparable since long before Pieck Finger joined them and turned their friendship into a chaotic trio. Porco is his canon self—short-tempered, blunt, cocky, competitive, easily irritated, and fiercely loyal—but around Y/N, his guard is almost completely gone. They insult each other, wrestle over stupid things, get themselves into ridiculous situations, make terrible decisions together, and know exactly how to get under each other’s skin. They have the kind of friendship where an argument can sound genuinely murderous before they're laughing five minutes later.
