Otherworlder
Overview
Otherworlder (이계인) literally means 'a person belonging to another world (異界)', and is a concept collectively referring to characters who operate against the backdrop of another world (異世界) in Korean genre literature such as fantasy, martial arts, and romance fantasy, as well as webtoons and games. In a narrow sense, it is used as an umbrella category encompassing both transmigrators (轉移者) who cross from the real world to another world and, conversely, beings who cross from another world into reality. Today, the expression 'otherworlder' itself has established itself as a genre convention (trope) and character archetype, functioning as a core device in designing narrative structures.

Concept and Etymology
'異界' is an old term that referred to realms outside the human world in Buddhist and Daoist worldviews, denoting spaces inhabited by ghosts or immortals (仙人). 'Otherworlder', combining this with '人' meaning person, appears to have taken root in Korea after the concept of 'isekai-jin (異世界人)' used in Japan's light novel culture since modern times was introduced. In Korea, it was first used in martial arts and fantasy fan creation culture in the 2000s, and spread as a popular term with the growth of web novel platforms in the 2010s.
Aspects by Genre
- Web novels and webtoons: This is the most actively used area, and among the four axes of regression, possession, transmigration, and reincarnation, transmigration and possession form the core of otherworlder narratives. The protagonist usually moves to a medieval fantasy world or martial arts world while retaining the values and knowledge of a modern Korean.
- Games: In Lost Ark, the 'Silin' (실린), and in many MMORPGs, otherworldly beings are used as setting devices that explain the hidden side of the worldview. The player character is also often an otherworlder.
- Animation and Japanese light novels: The genre became popular under the name 'isekai mono (異世界もの)', and the so-called 'truck accident' cliché of being reincarnated after being hit by a truck spread to internet memes.
- Martial arts fiction: The otherworlder setting is frequently deployed in the 'modern martial arts' subgenre, in which a modern person intrudes into the world of chivalry (俠).
Narrative Functions and Types
Otherworlders perform three major functions. First is the function of the reader surrogate (readability). Because the protagonist does not know the language and customs of the other world, the author can naturally explain the worldbuilding, and the reader learns the world from the same perspective as the protagonist. Second is the generator of value conflicts. Modern values such as democracy, capitalism, and human rights collide with status systems and magic systems, creating conflict. Third is the medium of metanarrative. Otherworlders often are aware that they are in a fictional world, so they are used as metafictional devices through which the work mocks or twists itself.
Typologically, they can be divided into ① the summoning type with a purpose (hero summoning), ② the castaway type who accidentally drifts, ③ the possession type who enters another person's body, and ④ the self-aware type born in the other world without memories. Recently, the 'multiple otherworlders' configuration, in which several otherworlders appear and conceal that they are from different worlds while opposing one another, has also increased.
Representative Works and Reception
In Korean web novels, many works in the martial arts and fantasy categories have featured otherworlders as protagonists, and the webtoon Omniscient Reader's Viewpoint is cited as a representative case that metafictionally reinterprets the otherworlder trope through the setting of 'a reader who enters the world of a novel'. In Japan, works such as Re:Zero - Starting Life in Another World and Mushoku Tensei led global success and established the genre's grammar. In criticism, there are both the observation that otherworlder narratives offer 'escape from reality' to readers and the analysis that they can simultaneously be read as allegories of migration, immigration, and refugee experience.
Recent Trends
As of 2024–2025, otherworlder narratives are evolving in a direction of dismantling the isekai grammar, which has reached saturation. First, return narratives have emerged. 'Returner fiction', which depicts the process by which a character who survived the other world and returned fails to adapt to everyday life, has established itself as a major web novel subgenre. Second, settings dealing with the legal and institutional status of otherworlders have increased. Works that translate immigration screening, identity forgery, and multiple nationality issues into fantasy grammar are drawing attention. Third, with the spread of generative AI, multilingual translation and fanworks have exploded, and worldbuilding expansion among fandoms sharing otherworlder settings has become active. Fourth, new media such as short-form dramas and interactive webtoons are recycling otherworlder clichés in compressed and immediate forms. In academia, discussions in Korean genre literature studies are expanding to interpret otherworlder narratives as 'postcolonial imagination' or 'allegories of the experience of compressed modernization'.
