Eira's expression didn't change even as her brother explain the situation bringing up something that had completely slipped her mind. "Shit!" the curse that slipped out of Eira's mouth was something that happened only in response to moments where she was indeed wrong, forgetful, or caught by some other method. Perhaps she was a bit too stubborn for her own good, and perhaps she shouldn't always aim it at her elder brother. Honestly this was something she was trying to work on, but that was infinitely harder than she'd like to admit. 'I forgot I had planned to apologize...' Eira thought to herself, absently reaching up to rub her face. "Gomennasai, Nii-sama..." she said, meaning this and managing to look a bit like a chastised child, which was a face she didn't often have to give.
It seemed there was more to come than she'd like though as her brother mentioned that one of the things wanted from her was that she meet with Roxanna herself at some point before this particular match. Eira's eyes shifted, and she sighed. Sirtreize had already gone on to explain that he had no idea what the girl wanted from a meeting with her, but Eira hated such things. She specifically disliked being around this girl and her Peerage because of how she treated them. "Uh-huh... that's great," she managed sounding about as sarcastic as she could but not aiming that at this man and instead at the universe at large. But when the conversation came back around to what she'd wanted to speak with him about her eyes widened just a bit. "Oh. That. Well... see I have a kind of weird question," she prefaced her inquiry strangely but this was mostly because this was an awkward topic to broach no matter how she looked at it. That being said there was no one she could or would ask aside from her brother. "So, I marked Takumi and that's cool, but I uh... have feed off him a lot and he claimed he wasn't tired. And, he got a really strange transformation this morning... and I don't have any reference for that sort of thing... and I don't really know if it's okay. I understand he should feel tired at some point and I don't know why he doesn't or if I did something... and I'm really worried about it. Uh... do you know what I am talking about at all?" she asked her brother, managing to look more than a bit bashed, much like she imagined human children were with their older siblings upon discovering the normal side of what she was talking about.
