Tsuzumi still remembers the beating he had one time from his superior - not Hitomi, thankfully - for sleeping on duty. He gulps a bit and looks at the wall, ignoring the fact that she was circling around him. He started to sweat however, but he ignores this as well.
"I start losing in the game, madam." He tries to cope with that very neutrally, as nothing like this happened before. His voice becomes more confident, right after he takes a deep breath. "I became a bit hot-headed, Sakuma-sama; losing my money and... That is all I believe."
He is aware of the voices around, but he is already ignoring them, being able to focus onto his superior - a thing that he have learnt some time ago to improve his close-combat skills. And learning, of course.
