Tenrakugai -Shoujo Isekai Touhontan-

It was a common school rumor. But that story was... real. Moka, Midori, and Sayu passed through a door and arrived in another world, it was a world that reminded them of the Middle Ages, like something you'd see in a fantasy movie. The life in the other world was full of excitement that was different from everyday life, and the three enjoyed it. But one day, a sudden crack in the ground swallowed up the town, and the three were unable to return to their original world. At the bottom of the crack, in an isolated town, the three ended up living with the survivors, men who happened to be staying in the town and that called themselves adventurers, and the townspeople who originally lived in the town. These two groups of people naturally ended up living separately in the east and west of the town. As they continued to live like that, Midori was raped by the adventurers. The incident that happened caused the relationship between the three to break down, and the town eventually became completely divided into east and west. What kind of future will the three find themselves in the midst of the conflicts in the chaotic city?
