Having saved the kingdom from invasion, Mitsuha suddenly finds herself elevated to the rank of viscountess. Exploiting her world-jumping ability to the fullest, she’s now busy improving things in her new domain (with a little help from Earth’s advanced knowledge and technical skills).

Between that and the arrival of unexpected visitors from a distant land, the newly-minted Viscountess Mitsuha von Yamano really has her hands full!
