In the past, Takeshi was a bartender at a prestigious hotel in Yokohama. After arguing with a floor manager, he was fired and he returned to his hometown Dobuita, where he opened a bar called MJQ Jazz Bar where he can listen to his favorite jazz music while lavishing attention on his customers. The bar has had good reviews in the local press, so business has been thriving, although some customers ruin the atmosphere of the bar, which irritates Hirai to no end.
