Subaru:  “…That gets right to the nature of it, though.”

Meili:  “…Oh, when did you come in, mister?” Ignoring Subaru’s comments about her naming sense, Meili cocked her head quizzically. Apparently, she was willing to let bygones be bygones and pretend nothing had happened. Subaru was perfectly happy to go along with it.

Subaru:  “? What do you mean, Meili? Why did you suddenly—?”
gpt
Meili:  “Yeah, it’s been about a month, hasn’t it?! You weren’t lonely while we were away, were you?”
human
Subaru:  “Not really? It was Petra who was lonely without you around. You’re so bad, mister… Oh, new faces?” When Subaru interrupted Emilia, who couldn’t read a room for her life, they narrowly avoided upsetting Meili again. Now mollified, the young girl was busy setting up her dolls on a shelf when she noticed Anastasia and Julius.

Anastasia:  Anastasia’s expression softened as she watched how the girl changed so quickly. "That’s fitting for a girl her age. Compared to Mimi, the way she leads people around is downright cute.”

Julius:  “…That’s certainly one way to put it. We should be grateful to Mimi.” The lady and her retainer shared a moment of odd understanding.

Julius:  Meanwhile, Julius’s yellow eyes scanned the room. “Still, I imagined a harsher environment for something called a prison… This is quite different from what I had pictured.”
human
Emilia:  Emilia’s eyes fell to the floor as she murmured regretfully. “She is a young girl, and it’s not like we want to make her suffer…but we can’t really just let her out, either, so it’s complicated.” As Julius indicated, the prison—the space where Meili was being kept—allowed her more freedom than even the most low-security jail. It had originally been a simple stone room, but the walls had been painted bright colors, and there was a simple but comfortable carpet lining the floor. There wasn’t much limiting her movements inside the room, and all the dolls Subaru had made for her were neatly lined up on a shelf. There were even books and toys to keep her entertained. In other words, it was the sort of place a shut-in could live in peace and comfort. A part of Subaru would have loved to just hole up there himself.

Julius:  “—But this unique atmosphere is emanating from her.” Julius scanned the room again, before looking at Meili specifically.

Meili:  She smiled at his observation. The sinister air that emanated from every pore of her body was the reason she was being held there.

Subaru:  “Like I mentioned in the carriage, this girl…Meili was originally an assassin of sorts who was trying to kill Emilia-tan and everyone else here. Make sense so far?”
human
Julius:  “Can’t say it does, but let’s hear the rest.”
gpt
Subaru:  “Feels like you’re thinking of something else, but whatever. Anyway, she was an assassin. As for the method she used, put simply, she can control demon beasts.”

Meili:  “Yep, I get along really good with bad animals."
