"A lone knight wanders far and wide looking for the one who can save this world"
Since time immemorial, members of Unicorn's family have served individuals considered to be the saviors of the world. When Unicorn turned 14, she was sent on a journey to find the current generation's savior—the person destined to be her master—just like her father had when he had been her age. To aid her in her efforts, she was entrusted with her family's heirloom, a diadem adorned with a single horn—Chevalier's Grace.
