Ihara Mitsuru , who grew up in the orphanage "Tsukushien," is a cleaner at Miyazono General Foods, a prestigious company. However, Mitsuru has another side to him: he is a fighter in "Food Fight," a competitive eating gambling game hosted by the chairman of Miyazono General Foods and held in the company's basement, where only bigwigs from the political and business world can participate. Mitsuru anonymously donates the prize money he wins from Food Fight to Tsukushien, and his desire to do so allows his talent to blossom, leading him to reign as the unbeatable champion.
After growing up in an orphanage, Mitsuru Ihara started working as a custodian at a large food producer. The pleasant, kind Ihara often visits his former home, pretending to be an important business man, not the blue-collar cleaner that he really is. But there's another, bigger secret: He is the reigning champion in an underground eating competition held at the company. In it, two contestants battle to see which can pack away more food within a time limit. The noble Ihara, with nine consecutive wins, always donates the money anonymously to his orphanage. The circumstances surrounding his victories, however, are often surprising and usually unusual. --NTV
