The original manga author of "旋风管家" is Kenjiro Hata, and his work has been serialized in Weekly Shonen Magazine. The story tells of a first-year student at a public high school named Ayase Ryo, who, due to his parents' lazy and wasteful nature, has to work every day to support his family. On Christmas Eve, when Ayase Ryo returns home, he finds that his parents have left him with a blank check. It turns out that his parents fled after owing 150 million yen in debt. To pay off the debt, they even attempted to sell Ayase Ryo's organs, which is utterly immoral. Being chased by the yakuza and with no way out, Ayase Ryo plans to kidnap a girl from a nearby park for ransom. Rushing over, he says to the girl, "I need you as a hostage." Of course, before he could finish these last two words, a series of misunderstandings occur, and Ayase Ryo ends up becoming the girl's savior instead. It turns out that this girl is the heiress of the Sanzenin financial empire. To repay her debt of gratitude, she hires Ayase Ryo as her butler and repays his debt. However, the kind-hearted Ayase Ryo insists on repaying this money, and thus begins his life as a butler.
