In truth, contact between Eren and Historia could awaken their memories, but Chen Si worried that Eren might awaken even more memories and turn dark ahead of time.
Chen Si recalled the dream he had when he first arrived in this world. A woman was being devoured by a Titan-that was Mikasa's mother. And the girl swallowed by artillery fire was... Mikasa...
What did that dream really mean? Could my presence put their lives in danger too? The first dream came true. What about the second... Chen Si still wasn't mentally prepared.
What am I afraid of... I'm so strong. How could anything happen to Mikasa?
"Older Brother..." Mikasa noticed the worry in Chen Si's eyes and took his hand, her voice full of concern.
"Mikasa, I'll make sure you live your whole life freely, just as you please," Chen Si said solemnly, tightening his grip on her hand.
"Mm." Mikasa's face flushed crimson, and she lowered her head, unable to meet his eyes.
"Tch." Levi spoiled the mood with a scoff.
"Levi, don't be jealous of him. No girls like you, but he's got plenty," Hange teased, patting Levi on the back.
"Shut your mouth, four-eyes."
"Historia, I can restore your memories. Do you... want to know the truth? Honestly, I think it would be better if you didn't remember..." Chen Si asked Historia.
"I want to know! I don't want to spend my whole life in the dark. I'll be fine," Historia declared firmly, without a moment's hesitation.
"All right."
Chen Si slowly closed his eyes. His Divine Sense penetrated Historia's brain, where he discovered a small patch shrouded in mist. He held her head in both hands, and arcs of electricity began winding around them, converging above Historia's head.
"Whoa! What's this?" Hange watched with shining eyes.
