20 years prior, Ichirou had left Japan to study cuisine in France, leaving his lover Mayako and their dream to open a restaraunt together behind. Before leaving, Mayako had finally been able to purchase the mansion she had wanted, but he felt that he was too good to open a restaraunt in the house.
Later, he returned to Japan after achieving fame, though he only looked upon Mayako's mansion, afraid to go in. After Hawk's Eye's attack, he summons up the courage to do so. He had realized that he had been selfish, and through all his years, he had never found anything better than her stew. The two lovers reconcile, and soon open up Rokuten Restaraunt.
