It took close to two weeks for Erich and Ayumi to return to Teutonia after stepping through the warp gate, which took them from the world of Alfheim to the world of Germania. It was only after the couple were at the doors of their home did they feel relieved.
And yet there was still a deep sense of anxiety in Erich's gut, because the day was quickly approaching that he would have to give Lunaria an answer. He had been thinking about how he was going to resolve this issue during every free moment he had up until this point. And there was only one conclusion he could land upon. He would have to accept his fate and agree to Lunaria's demands.
After all, it was only after he had time to think that Erich realized the odds of him escaping from the Alfheim Empress's clutches with his life intact were virtually zero. Especially now that she had set her sights upon him. He doubted there was anything in this galaxy more terrifying than that woman when she felt scorned.
