OK my Japanese sucks, but it sounds like "Ore no ban da na," probably 「俺の番だな」 which means something like "my turn now, right?" One of the other party members (Han IIRC, possibly one or more others) has "Watashi no ban desu ne," 「私の番ですね。」 which has basically the same literal meaning but a slightly more formal style.
What is Ore Wa? To put it simply, Ore Wa (俺は) is a Japanese pronoun used by men to refer to themselves. In other words, it’s a way for men to say “I”, which is used in casual or informal situations. Often, Ore Wa is used to express confidence, assertiveness, or a sense of dominance.
