The man looks at his... No, whoever this woman happens to be? They are not his former enemy. He'd bow to her for a moment before looking up again, eyes still wary, but aimed around them rather than at her.
"I see then... One moment I was in the ruins of Tokyo, and the next I find myself here staring at someone wearing a suit of armor I'd thought was gone forever. In spite of looking like, someone, I once fought against, you are quite clearly not her."
He'd look over towards the doors and Sayaka kicking at them... What on the name of Masakado is that girl doing? Regardless, might as well introduce himself before talking more.
"At any rate, my manners seem to have escaped me for a moment. I am Flynn, Samurai of Mikado, and some might say Hero of Tokyo, regardless of that, however..."
He turns back to The Black Samurai look alike, quite curious upon hearing her claims of the person in charge here wanting to take over the world.
"If your claims hold true, then I've no choice but to raise my blade against this person myself, I'll need to see more of the situation before making any judgment calls final. But for now... I suppose you may consider me an ally."
His voice is rather loud upon stating his name and intent to aid them, no sense having to say this twice after all. Finally, Flynn turns over to Sayaka and shakes his head at her rather foolish attempts to use brute force.
"And may I ask, why exactly do you think that simply smashing through things is going to work here... Miss with blue hair? I somehow doubt that a human can tear it down, even one with obvious supernatural strength such as yourself."
