With the concept of escapism at its core, the Isekai genre has become increasingly popular over the years as new series with distinct storylines populate this category. A common trope in anime, an "isekai" refers to a story where a character, usually from the mundane modern world, finds themselves in a world that is fantastical, bizarre, or otherwise drastically different from the one they know. Some such stories follow the protagonist embarking on a journey in their new life. Others heroes find themselves desperately looking for ways to return home. In between these two classifications is another type: one where characters can freely go back and forth between the alternate dimensions.
