Who is the disguise/pragmatic character? Explain his/her identity

In my opinion, Bluntschli is the most pragmatic character in the play. He is unconcerned with romantic ideas about heroism or conduct in war; he is concerned with professional conduct, efficiency and survival. Yet Bluntschli has a romantic heart and returns to see Raina, whom he has become taken with. During his visit he learns of his father's death, resulting in his inheritance of a large sum of money. Eventually Bluntschli overcomes Raina's posturing and asks for her hand in marriage, using his newly inherited wealth to win Major Petkoff's approval.
