Yume ni Aruku is a four-part series which is set in a universe similar to that of Innocence Seekers. It follows three different groups of girls as they wander into a world named Kariuba, which had isolated itself from Earth and the rest of the galaxy in the aftermath of a massive war between the two worlds.
The first three parts will each follow a different group of girls, and their stories will be largely separate. However, there will be some overlap between the stories, especially since all of the girls go to the same school. The fourth and final part will bring the groups of girls together.
More will be posted at a later date.
