Tatsunoko started to laugh out loud.
"Honestly, I hoped it would attract a proper servant... But all I got is this christian dog..." Tatsunoko said with a smug look on his face, trying to enrage his servant more.
Tatsunoko started to think, what if he just got rid of his servant, and then killed another master? Would that make him the new answer?
Tatsunoko looked back towards Roland, as he wasn't even paying attention, and he noticed he was about to strike Tatsunoko down with his blade.
Tatsunoko extended his right hand, which contained his command seals, and he exclaimed: "You filthy dog... Place your left hand on the table, and cut of your thumb with your sword!" He shouted, with an evils mile on his face, knowing he was in total control as long as he used one of those command seals.
Tatsunoko wanted to embarrass his servant in front of all the other master and servants, and wanted to showcase what happens if you don't listen to your master.
