Hana no Kishi

Ran Kurono has committed herself to becoming the First Knight of the next Ohtori family head, a role her family has held for generations, after her brother died protecting Sei Ohtori. To achieve this, she hides her gender. Eleven other knights, each with their own ambitions, also seek the position. Meanwhile, Sei is undergoing evaluation to determine his suitability as the family's new leader. Both face challenges at Saint Locks Academy, where Sei's disheveled and unpolished fiancé, Ibara Tennou, offers them support.
