Zetsuran is the daughter of the Dragon King and is originally from Coulomb Island, a stronghold of the Dragon Tribe. She has the power to show people memories. When she was little, she trained with Twilight for a year, always competing with him in various tasks. Zetsuran is jealous that Princess Suya is treated lavishly, as Zetsuran herself had been taken hostage before by humans but treated poorly, and had to break out on her own after waiting in vain for Twilight to help her. She later discovers that it's because Twilight assumed Zetsuran was a man, and was unaware that she was the one who'd been kidnapped.
