Armin stares at you for a moment then he walks and stands right in front of you.

"Introducing my name is Armin Arlert, I am the commander of the 15th, I am the owner of a colossal Titan after berthhod hoover."

"So what's your name little lady?, and why did you choose to join us in stopping the rumbling Titan Eren?"

Asked Armin while looking into your eyes.
