Isekai — Otherworld fantasy centered on a protagonist’s second chance
Isekai refers to a narrative genre of fantasy whose central principle is based on the passage of a protagonist into another world. This transition can take various forms—transportation, summoning, reincarnation, or a more ambiguous shift—but it always implies a rupture with the original world and entry into a universe governed by its own rules. The term isekai literally means “other world” in Japanese and refers to this idea of a radical change in setting and trajectory.
In an isekai narrative, the protagonist generally retains a consciousness, memory, or identity from their previous world. This continuity plays a central role: it creates a contrast between the individual and the new universe in which they now exist, and serves as a narrative anchor for exploring new systems, hierarchies, and possibilities. Isekai is therefore not limited to a simple change of scenery; it stages a confrontation between two distinct world logics.
The genre is frequently associated with the notion of a second chance. While not systematic, this idea runs through many narratives: the transition to another world allows the protagonist to rebuild themselves, correct past failures, or redefine their place within a different framework. This dimension gives isekai both a narrative and symbolic scope, where personal progression is closely tied to the discovery of the new world.
Isekai developed primarily within the realms of fantasy and the light novel, before branching into numerous forms, sometimes hybrid in nature. Whether it emphasizes action, reflection, progression, or exploration, the genre consistently relies on the relationship between a displaced protagonist and an otherworldly setting whose rules, limits, and stakes must be understood.
