Maou to Yuusha ni Dekiai Sarete, Oteage Desu!

Claire was reincarnated into a magical world where she became the demon lord Noah's secretary. Noah treats her well and she enjoys her life there. But then Claire was pulled through a magical portal to the hero Ilwert, on a mission to seal away the demon lord. Claire reluctantly follows along, hoping to return to her home at the demon lord's castle. But for some reason Ilwert is extremely sweet to her, too? Being doted on from both sides―it's too much to handle!
