While her hands were resting on her luggage handle Koken looked to the woman, newly introduced as Ms. Shiba, as soon as she felt that aura pressure. People might have taken this aura as 'scary' or whatnot, but Koken on the other hand was fearless towards it. It was extremely intimidating of course, but overall it appeared Koken was not phased. Although, that does not make her cocky either. Sure she should probably be worried as hell if she's in some sort of fit with her, but Koken was smart enough not to mess around with this Ms. Shiba persona. 

Koken moved in front of her luggage to sit on it, leaving the luggage standing up as she leaned slightly back and crossed her arms. It was shortly after when Koken lightly tugged on her hoodie, feeling a sudden heat. Koken's head perked slightly, another aura pressure perhaps? Koken slowly glanced around to find the source of the pressure being emitted. Eventually she took notice of the young man. Dark hair, blue eyes and all. Staring at him who was talking to the short blonde girl for a short bit, it was probably right to assume the heated aura pressure was coming from him. Koken cracked a smirk as she closed her eyes and slightly shook her head while looking a little downward, [color=black][i]'Psh. Show off,'[/i][/color] she thought as she did so. Externally, she even let out a small chuckle. Koken was actually kind of tempted to emit some of her aura herself, but she decided against it rather quickly. Although it would be entertaining to see some reactions, she didn't really see a real reason to do so. Besides, it might serve better for later. If worthy, that is.

Around now some people started socializing with one another; Koken didn't bother to join in, yet. Koken usually refers to herself as [i]somewhat[/i] antisocial. Only somewhat because it's true that she usually isn't the one to go up and start conversation, but if talked to she doesn't mind. If she were to ever go up and start talking first, she probably has some kind of a good reason. In all honesty, she switches off every now and then. More like once in a blue moon, but eh Koken does whatever she feels.
