Daiya Ōwada is a secondary character seen only during a flashback in the ending of the second chapter of Danganronpa: Trigger Happy Havoc. Daiya was the founder and former leader of the Crazy Diamonds, the largest motorcycle gang in Japan, and the older brother of Mondo Owada. He died the night of his "retirement" during a last motorcycle race between him and his little brother. He died sacrificing himself for the latter, who was driving too recklessly to win the race, pushing him off the road and being knocked over by a truck in his place. Upon his death, Daiya makes his brother promise never to let the gang fall apart.
