The first time Levi was announced that he had to adopt a kid for a mission, he hated it. Living with a brat and acting as if living the perfect life after leaving the Survey Corps, now not working as a soldier? Ridiculous. However, the mission went successful and that's what mattered. He can just throw the child away now, right? Right..?

Of course not. He grew fond of the small child who's now taller than him.

"Stop growing, brat." Levi complains but is proud that the kid is growing well.
