Bride of the Barrier Master - S01

Long ago, Japan was protected by five crystal pillars. Eighteen-year-old Hana Ichise was born into one of the branch families that defend the pillars with supernatural abilities, but she has lived in the shadow of her brilliant twin sister, Hazuki, since childhood. When Hana finally awakens to powers of her own one day, she chooses to hide them because she wants to finish high school in peace. That is until Saku Ichinomiya, the arrogant yet powerful head of her family's primary branch, falls for Hana and forces her to sign a marriage contract with him. But can Hana reach her true potential under the wing of her husband-to-be?
