"So why did Reiss take Historia and Eren? Does he have some specific goal?" Armin asked the question on his mind.
Armin's question left everyone silent.
"That guy probably wants Historia to inherit Eren's Power of the Titan," Ymir suddenly said from beside them.
"What do you mean, Ymir?" Hange asked.
"Didn't I tell you how I got my Power of the Titan?" Ymir reminded them.
At Ymir's reminder, Hange froze for a moment, then slapped her forehead.
"So that's it!" Realization dawned on Hange's face.
"Four-eyes, what exactly does that mean?" Levi asked curiously.
"Didn't Ymir say she used to be a Pure Titan wandering outside the walls? By chance, she ate Reiner's companion, and afterward, she turned back into a human. She also gained the Power of the Titan, which let her transform at will."
Armin's expression changed at those words. He grasped the key point and hurriedly said,
"So if a Titan eats a human who possesses the Power of the Titan, they can turn back into a human and gain that person's ability!"
"That should be how it works." Hange nodded.
"Wait... what were you just saying? Ymir used to be a Pure Titan wandering outside the walls?" Arthur interrupted the two, staring at Ymir in disbelief as he questioned her.
"You were unconscious at the time. We questioned Ymir and learned how she got her Power of the Titan. There's something else I forgot to tell you. After investigating Connie's home village, Ragako, we concluded that the Titans that appeared inside Wall Rose were very likely deliberately transformed by someone," Hange explained to Arthur.
Hearing this, Arthur felt an enormous amount of information crash into his mind.
Ymir was one thing, but he had never imagined that those man-eating Titans had been transformed from humans
