Kai blinked afew times and slowly looked back to make sure nothing was there, sighing in relief after seeing nothing, yet still had an odd feeling on him as he followed her to the steps and fought off the instinct to run out of the building, even though apart of his brain was screaming it at him, having to shake his head before focusing on the stairs. Focus! You're a Kamen Rider! He nodded to himself as he followed up the stairs, though having to hold onto the railing halfway up. He just about jumped when he heard a step crack, nodding some at Grace as he followed. He was glad to be on some solid ground again as they got to the second floor, looking down the hall and rubbed his hands some out of nervousness. "Uh...well..um..." He looked at each door before snorting, giving a determined nod. "Lets let fate decide!" With that, he closed his eyes, put his hand out and stormed to the first door on the left, going to nudge it open.
