Because I, the True Saint, was Banished, that Country is Done For!
By Shikiso Utsuzawa, Mokuba Matsu and Pukyunosuke
Ever since she was a child, Eliane has been the saint and protector of the Kingdom of Belkheim, warding off monsters and ensuring bountiful harvests with her prayers. But when a pretender saint beguiles the foolish prince—to whom she is engaged—into believing she is nothing but a fraud, he calls off the marriage and banishes her from the kingdom. Homeless and penniless but free to chart her own course for the first time in her life, Eliane decides to make for the neighboring kingdom, where she hopes to blend in as a commoner and lead a quiet life…but a chance encounter on the road will totally upend her modest plans.

Despite its bad reputation, monster meat can be used in exquisite cuisine and Melphiera is determined to change the kingdom’s opinion of it! Unfortunately, since debuting in society, Melphiera has been struggling to find her perfect match…until she meets the fearless “Blood-Mad Duke” of Galbraith!
