"Corentine, stop acting quiet, we already know that..." Takahisa sighed and looked to his side to look at Corentine, but saw that she somehow managed to slip away unnoticed,"...oh, she left."
"Oh, Kaika, is this your little brother?" Umiya came downstairs to see them, not caring that she wasn't really that well known to Kuro in the first place.
"Kaika, who's that?....and why is her hair blue?" Kuro asked, a little confused, and before Kaika could answer, Umiya had woven up a great lie already.
"Apologies, I'm Umiya Narue, the person that owns this household. Since Kaika, Peyton, and Eren are transfer students here, I was the one to offer a place for them to stay," she said almost immediately, and then added,"Also, I use hair dye for certain, it's a way of self-expression."
