At some point, he'll be found by familiar faces. At some point, a lot will be explained to him. And very likely he'll end up dragged down under the sea to the house they were all already staying in. All of those sorts of things. After all that though, at some point while he's touring the house, or getting food, or anything else he feels he needs to do to get settled in, he may notice... eyes.

Eyes and a forehead to be precise, peering over at him from just over the top of the couch.

Shy as a stray cat, Futaba watches the newcomer nervously. Like on one hand she knows, she knows she knows she knows this guy is Kanji and Naoto's friend. From Naoto's email she knows that he is to them what Ren is to them all. But. But. There's still a stranger in her house. And there was no easing into it, like there had been with Naoto and Kanji, nor was it washed out with the general discomfort of everything being new, like there had been with that Minako girl.

So she's just going to watch, warily, to the point of staring. Letting him make the actual first move though.
