Isekai is a subgenre of fantasy anime that typically involves the main characters of the story being whisked away to another realm. While the characters struggle to adapt to their new circumstances, these tales explore concepts such as friendship, magic, and adventuring. Though some shows involve characters traveling fantastical worlds, there are several examples of isekai anime that take place in a single city.
The characters' daily lives in the city and the challenges they confront adjusting to their new surroundings are the primary subjects of these tales. Characters in these anime are adapting to life in a new place, making new friends, and figuring out how to stay alive in their new surroundings. Although the stories and characters in each of these anime are distinct, they all tackle the challenges of adjusting to unfamiliar surroundings and the search for a community in which one may feel at home.
In most cases, the upcoming anime have occasional arcs set outside the main city, but the characters are based within a specific location.
