Ishi Kataoka lives within the cold streets of Skylight City. Not exactly a hero and not very smart either but he has a huge heart. He was trained by his masters Nana and Izusa ever since he was just a little brat in martial arts and street fights. Where he bravely fights his foes and wins the heart of a few ladies along the way. Until one day he rescued the mayor's daughter, who wants to marry and have his children! Ishi will face many challenges and many friends and foes along the way!
