Bride of the Barrier Master - S01

Long ago, Japan relied on five crystal pillars for protection. Eighteen-year-old Hana Ichise comes from one of the branch families tasked with guarding these pillars using supernatural abilities, but she has always lived in the shadow of her gifted twin sister, Hazuki. When Hana finally awakens to her own powers, she chooses to keep them hidden, hoping to finish high school without drawing attention. But her plans are upended when Saku Ichinomiya, the proud and formidable leader of her family's main branch, takes an interest in her and pressures her into a marriage contract. Now, Hana must figure out whether she can embrace her full potential under the guidance of her future husband.
