Akemi's head was cocked ever so slightly to the right while she looked at the man that had approached the table, requesting permission to sit. Not that he technically needed it; the seat was open, unclaimed, and nothing she was doing (nor anything her brother was doing) was actively barring him from making use of it. Perhaps this was an example of social dynamics? Unwritten rules demanding a certain explicit permission due to proximity? These were the difficult questions. Still, after a slight pause, she gestured permissively at the chair in question with one hand while taking a bite of her food with the other.

"It's open." She said simply, casting a sidelong look to her brother as if inquiring as to his opinion. "We arrived recently. Unfamiliarity is not surprising."
