She Is from Parallel Yokohama

The title and text are tentative and may be changed. After Dazai, his partner and lover, jumped off the roof of the building, Haitang, who had long been mentally prepared for this, calmly handled the handover matters in the future under the worried eyes of his subordinates, and planned to travel around the world. By chance, Haitang connected in the future with Zhongyuan Zhongya, the carrier of the wild tyrants who had the same origin as him in the parallel world. Haitang, who has no nostalgia for this world, traveled to the parallel world where Zhongyuan Zhongya lived in the future at the cost of one sight and one foot. Osamu Dazai in the parallel world is completely different from the port Mafia BOSS in Haitang's future memory. Her Dazai will never come back, and Haitang, who realizes this, decides to stay away from superpowers in the parallel world and be an ordinary person in the future. However, I encountered a harsh reality... I finally rented a house that I was satisfied with, but there seemed to be a death student in my neighbor's house. I finally found a job serving food in the school cafeteria, but the students in the school seemed to be playing super-powered tennis and disappearing basketballs. I finally accepted the fact. No matter how strange the people around me were, it would be fine as long as I stayed away from them. However, in the middle of the night, a strange creature knocked on the window, saying that she was their new demon princess. The reason is that she has one look and one foot. Forget it, anyway, the demon princess just solves the daily chores of the demon clan who don't have enough brains. But... Why did the Holy Grail War suddenly break out? … What about the promised life of ordinary people? I have been in Japan since I can remember, and Oda Sakunosuke commented that "even in Japan, Haitang, you are an extremely evil person." I seem to be forced to save Yokohama? PS: 1.+The heroine is super strong 2. + The heroine's outlook on life was formed in a career of licking blood from a knife edge, so she may be strange occasionally, but she is not a bad person in essence. Intention: What you love is separated by mountains and seas, and mountains and seas can be leveled.
