Rabian runs the Scheherazade Theater and is known for putting on plays. He's best known for hiring Team Natsu to stage a production in Onibus Town, though the job turned out to be more demanding than they expected.
His plays are notorious for being over-the-top with bizarre plot twists—"Frederick and Yanderica" being a prime example, packed with so much confusion that audiences couldn't follow it. The bad reviews and actor turnover that followed clearly took their toll on him. When Team Natsu first met him, he came across as genuinely miserable about his situation, but it didn't take long for his true nature to show. He has a tendency to go to extremes: he made the team perform the same play three times daily for a week and then refused to pay them. There's something darkly funny about how he peppers almost every sentence with "Thank you very much!" while simultaneously treating his cast terribly—he even dismissed Team Natsu as amateurs despite them bringing in huge crowds for him all week.
