El Rey

During summer vacation, Gash and his friends go to Mount Fuji for a picnic. There, they meet a girl named Kotoha who carries a white magical book. The book contains a message revealing that Gash’s mother is hidden in a nearby forest cave. When they reach the cave, they find a blond young man named Wiseman already inside. To save him, Gash and the others venture deeper into the cave and accidentally enter another world. Soon after, the Black Knight-the strongest warrior-appears, believing Gash stole the 101st magical book. The Black Knight attacks them, forcing Gash and Kiyomaro to uncover the true culprit within 24 hours, or they’ll be trapped in this strange world forever.
