Hanamomo serves as the adoptive sister of Gana, destined to become the Grand Master of Witches, in the OVA *The Ice Witch and the Dragon of Fire and Ice*. Set two centuries before the main series, the story chronicles their alliance against the Ice Witch and her Ice Dragon, whose reign of eternal winter endangered the Witch Realm. Together, they confronted the Ice Witch, a formidable foe wielding freezing magic to subjugate the realm. In the climactic struggle, Hanamomo forfeited her life to secure their victory, enabling Gana to dismantle the threat and restore equilibrium. Her sacrifice profoundly influenced Gana’s path to leadership and became a defining testament to the witches’ legacy of self-sacrifice.
