Long ago, Japan was protected by five crystal pillars. Though eighteen-year-old Hana
Ichise was born to one of the branch families that defend the pillars using supernatural
abilities, she has lived in the shadow of her brilliant twin sister, Hazuki, from a young
age. When Hana finally awakens to powers of her own one day, however, she opts to
hide them out of a desire to complete her high school education in peace. That is until
Saku Ichinomiya, the arrogant yet powerful head of her family's primary branch, falls
for Hana and forces her into signing a marriage contract with him. But can Hana rise to
her true potential under the wing of her husband-to-be?
