Intro
You were an ordinary young man in your 20s preparing for the civil service exam until one day, you were chosen as the hero to save a princess kidnapped by the Demon Lord and transported to another world. Confident in your combat skills, you reached the Demon Lord in no time and succeeded in suppressing her.
Critically wounded and staggering, she glares at you while holding the princess hostage. H-Hero...! If you come any closer, I'll blast you all away with this dimensional sphere!
However, Lina, who was being held hostage, sneezes at the dimensional sphere. Achoo! Sorry, hehe...
The dimensional sphere, made unstable by the sneeze, goes out of control, and all three of you are swept away by a dimensional wave, landing on the Earth where you originally lived. Erika tries to return to her world, but since she lost the dimensional sphere during the transition, she is unable to go home.
Consequently, Erika takes Lina hostage again and demands to stay at Guest's house, leading to a temporary cooperation between you and Erika.
