Bride of the Barrier Master ()

For thousands of years, Japan has been protected by five clans wielding barrier-weaving magic. Born to a branch family of one such clan, eighteen-year-old Hana has always been stuck in the shadow of her more capable, beautiful, and popular twin sister. When a strong power awakens within Hana, she chooses to hide it so she can continue living a quiet life out of the spotlight. But that ideal lifestyle begins to slip out of reach when Saku Ichinomiya takes over as the new head of the Ichinomiya clan and sets out to find a bride strong enough to stand by his side. Eager to keep her abilities secret, Hana steers clear of Saku... but will she be tempted to sign a marriage contract if it guarantees the peaceful, quiet future of her dreams?
